La Palma Report for 2-June-2000

date:		2-June-2000, Thursday
observers:	Shine, Bush
weather (6:10): wind from NW (320), 19.9 km/s, T = 14.1C, H = 3%, some clouds
		in the morning (weather from INT this time, which is closer
		to us than NOT)

Target:         AR 9017, leader spot, trailer not in fov

Summary:

We got a long run in today on AR 9017 beginning at 8 UT to 18:43 with only a
few interuptions for technical problems and a quick look at AR 9026. Seeing
was variable in the good/fair range for most of the time with some very good
frames in the mid-afternoon. The wind finally changed this AM and is coming
from the "good" direction. There were clouds and haze in the early morning
delaying our start.

Program/setup:

Imaging Table with SVST AO system installed

1. SOUP Tunable filter
      Kodak Megaplus 4.2 camera VIII, gain = 12
      (gain changed to 20 at 12:46, yesterday it was
      also 12, not 20 as reported)
      Royac 12, m42c control program
      H alpha at -700, -350, 0, 350, 700 mA offsets
      6302 blue wing magnetograms

 2. G-band camera
      New Andover 4305A filter (PN ANDV6773)
      Kodak Megaplus 4.2 camera VII, gain = -6 dB
      (yesterday the gain was also -6, not 20 as reported)
      Royac 14, m42b control program
      20s frame selection interval, ~20ms exposures

 3. K-line camera
      3993A filter 3A fwhm
      Kodak Megaplus 4.2 lumogen camera IX, gain=+20dB
      Royac 11, m42a control program
      20s frame selection interval, ~ 80-100ms exposures

Technicalnotes:

The black hole has returned to the tunable filter. There is a dark spot
near the center with attentuation of about 20%.

There are some problems with the frame selection and probably not all of the
best frames are being saved. We have a possible solution for tomorrow.

The AO system worked well.

The gain on the TF camera was increased to 20 allowing a factor of 2 decrease
in exposure time with no noticable difference in quality.

No TF observations on 5576 yet though I took a quick look.

Plans for tomorrow:

We intend to start observing AR 9026 all day tomorrow. Our small fov will be
focused on the leader spot unless we find TRACE pointing elsewhere.

La Palma Report for 3-June-2000

date:		3-June-2000, Thursday
observers:	Shine, Bush
weather (6:40): wind from NW (320), 19.9 km/s, T = 14.1C, H = 3%, some clouds
		in the morning (weather from INT this time, which is closer
		to us than NOT)

Target:         AR 9026, entire region most of the time, coordinated with TRACE

Summary:

The seeing was not as good as yesterday and we stopped observing for some
spells in the afternoon. G band and K line recording began at 7:45 UT and
the TF system lagged until 8:06 UT. Observing continued continuously until
15:33 UT and then sporadically thereafter. The target AR 9026 had several
small flares and other activity. Seeing in the morning was in the fair/good
range with some nice frames. It was more variable in the afternoon with
some good seeing occasionally but mostly fair to poor. Some 5576 Dopplergram
test runs were made.

Flares caught include an M2 at 8:28 and a C7 at 14:18. These events looked
compact in H alpha invloving a filament structure wrapped around/within the
leader sunspot. There was an M6 flare at 19:16 somewhere (not located in the
NOAA report yet) just after we shut down.


Program/setup:

Imaging Table with SVST AO system installed

1. SOUP Tunable filter
      Kodak Megaplus 4.2 camera VIII, gain = 20
      Royac 12, m42c control program
      H alpha at -700, -350, 0, 350, 700 mA offsets
      6302 blue wing magnetograms
      some 5576 Dopplergrams

 2. G-band camera
      New Andover 4305A filter (PN ANDV6773)
      Kodak Megaplus 4.2 camera VII, gain = -6 dB
      Royac 14, m42b control program
      20s frame selection interval, ~20-30ms exposures

 3. K-line camera
      3993A filter 3A fwhm
      Kodak Megaplus 4.2 lumogen camera IX, gain=+20dB
      Royac 11, m42a control program
      20s frame selection interval, ~ 80-100ms exposures

Technicalnotes:

The new megaplus program (megaplus_pete) seems to have solved the frame
selection problem noticed yesterday. It has a bug in the flat field mode
when displaying the images but they are recorded correctly. The frame
selection does not seem to work as well on the H alpha images as before
unless we put the box on bright structures.

The AO system worked well when the seeing was OK.

No green flash yet.

Plans for tomorrow:

We intend to observe AR 9026 all day tomorrow in coordination with TRACE. The
TF observations will include 5576 Dopplergrams.

La Palma Report for 6-June-2000

Date:		6-June-2000, Tuesday
Observers:	Shine, Bush
Weather:	Clear with a dust layer
		Wind from E/SE at 25 m/s, 13 deg C, 44% humidity

Target:         AR 9026, entire region, coordinated with TRACE

Summary:

Highlight of the day - we observed today's X flares and hope to get
movies out in the next day or two.

The wind was too strong to setup the telescope at the beginning of the
day, and we did not get sunlight into the observing room until 9:00
UT.  Recording of the G-band, K-line and TF systems began at 9:30 UT.
The TF began with the SunspotE program and switched to the Ever2000
program at 10:40 UT.

The seeing was only fair during the day. The wind continued to come
from the East (over the caldera), and was fairly gusty. The dust was
not as heavy as the previous day. The AO was not usable except to
indicate focus adjustments.

The Tunable Filter was switched back to the SunspotE program at 11:50
UT.  All three camera systems recorded a series of flares between 13:00
and 14:30 UT: M2.7 peaking at 13:19 UT; X1.1 peaking at 13:39 UT and
M7.1 peaking at 14:01 UT. The seeing was only fair, but the flares
covered the field of view in both the K-line and H-alpha images. By the
time of the X2.3 flare that peaked at 15:25, the seeing was poor and
the tracker kept losing lock. The seeing continued to degrade and
observing was stopped at 15:45 UT.

Technical Notes:

We modified the frame selection portion of the observing program, and
ran it with all three camera systems. The frame selection worked much
more successfully than on the previous days. In addition to correcting
two indexing errors, the selection criteria was changed from the
absolute value of the differences to the square of the differences.

Plans for Tomorrow:

We intend to continue observations of AR 9026 all day tomorrow in 
coordination with TRACE. 

Setup & Observing Program:

Imaging table with SVST AO system installed.

La Palma Report for 7-June-2000

Date:		7-June-2000, Tuesday
Observers:	Shine, Bush
Weather:	Clear, 14 deg C, 4% humidity
		Wind from E/SE at 25 km/hr, 
		Extensive low marine cloud layer

Target:         AR 9026, entire region, coordinated with TRACE

Summary:

Another day another X flare: 
	we observed an X1.2 flare peaking at 15:53 UT.

The morning was clear with light winds, and we were able to begin
observing with all three cameras by 7:20 UT. The seeing was good to
moderate during the day.  The wind continued to come from the East,
and was stronger in the morning (~ 25 km/hr) than in the afternoon
(~10 km/hr).

The Tunable Filter observations began with the SunspotE program,
switched to the Ever2000 program at 8:40 UT, and back to the SunspotE
program at 9:56 UT. A new Tunable Filter program (EverFdop) which
makes 4 point doppler measurements in 5576 was run between 14:25 and
15:30 UT. The TF was switched to the Ever2000 program until 15:42 UT
when the SunspotE program was started to observing the evolving flare.

All three camera systems recorded the X1.1 flare at 15:53 UT; the
seeing was fair to moderate. The flare morphology was different than
both of the X flares on June 6: not as compact as the X2.3 and
extending over a different region that the X1.1. We stopped observing
at 18:55 UT.

Technical Notes:

We tested an intensity normalized frame selection for about 30 minutes
on the G-band camera. This normalized quality unfortunately selects
images that have much lower intensity caused by shutter anomalies. We
are considering other options to address this problem.

Plans for Tomorrow:

We intend to continue observations of AR 9026 all day tomorrow in 
coordination with TRACE and MDI. 

Setup & Observing Program:

Imaging table with SVST AO system installed.

Observers:      Shine, Bush
Weather:        Clear, 13 deg C, 3% humidity                
                Wind from S at 47 km/h

Target:         AR 9026, central region, coordinated with TRACE

Summary:

No X flares today, just a C3 about 9:42. Seeing was not good today and
only fair for a few hours in the AM. We began at about 8 UT and continued
observing with all systems until 11:05 UT when the G band camera was turned
off. All systems were stopped at 14:55 except for some testing in the clear
but fuzzy skies. The TF programs run or tested were Sunspote, Everonly, and
Ever2000. 

Technical Notes:

We ran some more frame selection tests and modified software to accomandate the
shutter variations in the G band camera and still pick the best one rather than
the brightest one. The black hole in the tunable filter has faded.

Plans for Tomorrow:

We intend to continue observations of AR 9026 all day tomorrow in 
coordination with TRACE.

La Palma Report for 9-June-2000

Date:           9-June-2000, Tuesday
Observers:      Shine, Bush, Strous
Weather:        Clear, 11 deg C, 8% humidity                
                Wind from E at 50 km/h

Target:         AR 9026, coordinated with TRACE

Summary:

Clear skies all day but seeing was generally fair (some good) in the AM
declining to poor in the early afternoon. Observations began about 7:50 UT and
continued to 14 UT with an interuption from 8:20-9:20 due to a problem with the
power. For most of the time we included the "round" spot to study MMF's and
sunspot oscillations. Part or all of the central fragmented spot was always
observed. We also ran from 15:01 - 15:30 for a small flare in AR 9026. The TF
programs run were Sunspote, Everfdop, and Ever2000. 

Technical Notes:

Louie Strous joined us yesterday. Dick Shine and Rock Bush will depart tomorrow
around noon.  The outside power dropped in voltage triggering general havoc. We
spent most of the day on the backup generator. We tried out the 1 A bandpass H
line filter for a while and recorded some umbral flashes during bad seeing. The
exposure time is about 200-300ms for reasonable images compared to 100ms for
the 3 A K line filter.

Plans for Saturday/Sunday/Monday:

We intend to continue observations of AR 9026 all weekend in  coordination with
TRACE.

La Palma Report for 10-June-2000

Date:           10-June-2000, Wednesday
Observers:      Strous, Shine, Bush
Weather:        Cloudy & Hazy, 12 deg C, 35% humidity
                Wind from E at 20 km/h

Target:         None, due to the weather.

Summary:

No data was recorded today.  The Sun was acquired late because of a
thick haze, and soon disappeared behind high clouds.  While the Sun
was visible, exposure times were long and the seeing was very bad:
granulation could be recognized only rarely in continuum images.  At
the end of the afternoon, we got some very light rain.

Technical Notes:

Dick Shine and Rock Bush left before noon.  Darrel Torgerson arrived
around 5 pm.

On the weather:

During the last few days clouds and haze have passed over the Canary
Islands in a continuous stream from the southwest.  The clouds
disappear once they get well past the Islands.  Yesterday the clouds
stayed mostly to the south and east of La Palma, but not today.  The
haze obscures the horizon and the ocean.  Each night, the humidity
drops to near-zero, but each morning it shoots back up to 25 - 35
percent.  The weather forecast for tomorrow does not look encouraging.

Plans for Sunday/Monday:

We intend to continue observations of AR 9026 all weekend in
coordination with TRACE, weather permitting.

Setup & Observing Program:

Irrelevant, due to the weather.

La Palma Report for 12-June-2000

Date:           12-June-2000, Monday
Observers:      Strous, Torgerson
Weather:        Clear, 10 deg C, 10 - 50% humidity                
                Wind from N/NE at 40 km/h

Target:         AR 9026, coordinated with TRACE

Summary:

Clear skies all day.  Observations began at 8:18 UT and lasted until
18:50 UT.  The seeing was fair at the beginning, improved to regularly
good at 9 UT, and stayed mostly good to excellent all day -- i.e., for
almost 10 hours.  Even when we had to stop, the seeing was still good.
We observed two lesser spots in AR 9026 which look like they form a
separate bipolar region that emerged perhaps yesterday.  (Due to
constant clouds, we were not able to take any observations yesterday.)
The TF ran program AR_FAST, which was modified to include H-alpha line
center and omit the 5576 continuum.

Technical Notes:

At 12:47 UT the K-line workstation (royac11) spontaneously shut down,
leading to a 10-minute break in the K-line observations.  At 18:43 UT
the K-line workstation could no longer find the directory where the
K-line observations were stored.  A manual reboot allowed it to find
its way again.  This symptom resembles the symptoms that preceded the
total failure of a hard drive last October, which led to the loss of a
day's worth of observations stored on that hard drive.  Alternative
data storage may be required during the remaining observation days.

At 13:35 UT and 18:26 UT, the TF program spontaneously quit, but was
manually restarted without any trouble.

After the regular TF observations were stopped at 18:47 UT, we
recorded a few minutes of 5576 -750 mA continuum in conjunction with
G-band observations, to calibrate the G-band observations for use as
surrogate 5576 continuum in calculating 5576 Dopplergrams.

Plans for Tuesday:

We intend to observe AR 9033 in coordination with TRACE.

Subject: La Palma sunshine

After two days of clouds, we're finally recording some good data.  We're
observing AR 9026, following the TRACE schedule.  Our field of view is
centered on four small pores arranged in the shape of a diamond, close to
the two minor sunspots in the active region; the penumbra of the main
sunspot is at the edge. 

AR 9030, a little way away, looks like a fairly young active region and is
more interesting to me, but I'm not sure it falls within the TRACE field
of view.

La Palma Report for 13-June-2000

Date:           13-June-2000, Tuesday
Observers:      Strous, Torgerson
Weather:        Clear, 10 deg C, 10 - 25% humidity                
                Wind from N at 35 km/h

Target:         AR 9037

Summary:

Clear skies all day.  Observations began at 7:54 UT and lasted until
18:39 UT.  The seeing was fair-good most of the day with stretches of
excellent seeing.  We observed AR 9037 all day.  This AR is a classic
bipolar region, and nothing very spectacular happened in it.  The TF
ran program AR_FAST, which was modified somewhat from yesterday.

Technical Notes:

It turns out our identifications of what AR we were observing
yesterday and this morning were off by about 45 degrees longitude
each, due to outdated AR position information which happened to fit
the recent locations of active regions on the disk.  Yesterday we
thought we were observing AR 9026 but were in fact observing AR 9033.
This morning we thought we were observing AR 9033 but in fact we were
observing AR 9037.  Most likely, there is no overlap between our field
of view and the field of view of TRACE yesterday and today.

We ran sequence AR_FAST, but modified it somewhat: We switched from
nominally circular polarization to nominally linear polarization for
the 6302 magnetogram observations, because R. Shine says that there is
so much additional polarization in the whole optical system that the
nominally linear states are actually closer to circular.  We also
reduced the number of wavelength positions in the 5576 line from five
to three, and increased the number of wavelength positions in H-alpha
from one to three, allowing for the construction of H-alpha
Dopplergrams while keeping the possibility of constructing 5576
Dopplergrams.

At 11:55 UT, the TF program spontaneously quit, but was manually
restarted without any trouble.

At 12:46 UT the K-line workstation (royac11) froze up and could not be
revived.  The machine was reset but would not correctly boot up again.
G. Hosinsky switched royac13 for royac11 and we could resume taking
K-line data at 13:35 UT.  G. Hosinsky later managed to boot up royac11
again, and we transferred the morning K-line observations from royac11
to royac14 (the G-band computer), just in case royac11 would fail
irrevocably later.  When royac14 started taking K-line images, there
were no other K-line images from today on its disk, so the image file
numbers started at 1 again.  This meant that for most K-line image
file numbers, there were two files: one from the morning, and one from
the afternoon.  After the observations ceased, we renumbered the
afternoon files so they form a consecutive and uninterrupted sequence
with the morning files.  We also combined the log files for the
morning and afternoon, though we didn't adjust the image numbers
there.

The time of today's royac11 failure was within one minute of the time
of yesterday's royac11 failure.  We hope this doesn't mean that the
problem is external to royac11 and that we'll see the same problem
again tomorrow with royac13.

At 15:40 UT, we noticed some some small pores that had drifted into
the field of view (with the afternoon image rotation).  We briefly
moved our field of view over there in hopes of catching some emerging
flux, but the spot tracker did not recognize the pores so we had to
return to the bigger sunspots in AR 9037.

After regular TF observations ceased, we recorded some 5576 -750 mA
continuum images and some H-alpha (6559.3 Angstrom) continuum images
together with G-band pictures, for calibration purposes.

During the afternoon, the royac14 field of view subarea that is used
to determine the image quality was stuck at the center of the field of
view and could not be changed.  At the end of the observations, the
observation computer program "test_m42a" did not want to quit and its
process had to be killed.  Restarting the program to record some flat
fields and dark current images failed.  After changing ownership of
"/tmp/m42a_pipe" from "root" to "obs", things proceeded as usual.

Plans for Wednesday:

We intend to continue to observe AR 9037, now in coordination with
TRACE.

La Palma Report for 14-June-2000

Date:           14-June-2000, Wednesday
Observers:      Strous, Torgerson
Weather:        Mostly clear, 10 - 14 deg C, 10 - 20% humidity
                Wind from N at 30 km/h

Target:         AR 9037

Summary:

Mostly clear skies all day, with some isolated high clouds around noon.
Observations began at 7:28 UT and lasted until 18:53 UT.  The seeing
started good to excellent and stayed quite good most of the day, with
increasing intervals of fair to poor seeing towards the end of the
afternoon, but usually with a decent number of good frames sprinkled
in for the frame selection to pick out.  We observed AR 9037 all day.
The two main sunspots have moved apart somewhat since yesterday.  The
TF ran program AR_FAST like yesterday.

Technical Notes:

At 10:47, 12:24, and 13:02 UT, we noticed that the TF program had
spontaneously quit, leading to perhaps a few minutes' worth of lost
data.  It would be convenient if the m42c program beeped when it lost
contact with the TF PC, so we'd notice immediately.

Observations were interrupted at 11:09 UT for ten minutes due to a
thick cloud passing in front of the Sun.

At 13:10 UT the G-band program got stuck.  Power-cycling the camera
controller fixed the problem, and at 13:23 the G-band observations
were back on track.

Plans for Thursday:

We intend to continue to observe AR 9037, in coordination with TRACE
and SOHO/CDS.

La Palma Report for 15-June-2000

Date:           15-June-2000, Thursday
Observers:      Strous, Torgerson
Weather:        Mostly clear, 12 - 17 deg C, 0 - 30% humidity
                Wind from E at 0 - 20 km/h

Target:         AR 9037

Summary:

Mostly clear skies all day, but with some clouds in the east at
sunrise, some thin high clouds all day, and a dirty haze developing.
Observations began at 8:07 UT (delayed a little because of the sunrise
clouds and because of bird droppings on the entrance lens) at very
good seeing, but quickly deteriorated to poor, until we gave up at
10:00 UT.  We observed AR 9037, which has clearly decayed since
yesterday.

Technical Notes:

None.

Plans for Friday:

We'll attempt to observe AR 9046 in the morning, in coordination with
TRACE, before Louis Strous departs for the airport to make it to the
SPD meeting.
