STATUS OF SUN & GBOs:
-----------------

Several DBs of N32, W55-90 Filament (31 May between 1 and 14:50 UT)
NOAA prediction of low activity except for AR 8048 (S29 E)
- On Sat, 31 May, EIT has a beautiful 304-A image at 1318 UT of a
prominence eruption on the west limb. LASCO saw a slow CME from this
event once they were back on the W. limb, then saw a "sympathetic" CME
on the east limb, closer to the equator.
- EIT saw an apparent "zipper event" in 195A from about 0230-0500 UT.
The polar crown filament from central meridian to the SE showed rapid
motion and flows, with apparent interaction with loops from the AR
in the SE (NOAA AR 8048).
- LASCO C1 from 1230 UT today shows large loops above the NE, NW, SE,
and SW limbs, like four "ears", with gaps in the equatorial region.
C2 shows a couple of bright streamers on the west, and a rather diffuse
equatorial brightening on the E. limb.
- The MDI full-disk magnetogram shows lots of concentrated flux
in AR 8048.

GBOs:
----
- There has been no news yet from the Lockheed Martin solar physics
group currently at La Palma, who are observing at the Swedish Vacuum
Tower Telescope for the first half of June. They plan high-cadence,
high-resolution observations of small scale magnetic elements in a
1 arcmin square FOV. The best seeing periods are typically 0900-1200 UT.

Very good observations today for:
 - THEMIS (Halpha profiles with IPM-Italian filter) : JOP12/17
 - and Pic du Midi

CDS, SUMER and EIT: nominal



INSTRUMENT PLANS FOR JUNE 3:
----------------------------

CDS      0:00 -  6:00 : Synoptic meridian image
         6:30 -  8:10 : JOP 17 (S43, W64) with SUMER
         8:10 - 10:00 : FOV1 Filament channel (N25, W17) with EIT
        10:00 - 12:00 : FOV2 Filament channel (N25, W17)
        12:00 - 16:00 : JOP 33: Active Region study (S29 E8)
        16:00 - 19:00 : Filament Study/ with VLA (395, 112)
        19:30 - 23:30 : Stray-Light study


EIT      Supports JOP 17  (304)  and VLA (195)


SUMER
        0:00 - 6:30 : High Velocity Events
        6:30 - 9:00 : JOP 17 (S43, W64)
        9:00- 12:00: JOP 12 Prominence Study (742, -602) (S35, W)

        13:00- 16:00: Spectral Atlas of Active Region SW
        16:00- 24:00:  Off limb High Velocity Events


UVCS, LASCO, and MDI: nominal

UVCS: In addition to usual synoptic program, today will make polar scans 
at N. pole from 1.5 to 1.8 R_Sun. Tomorrow: will make scans at 1.5, 2.0, 
2.3 R_Sun.

LASCO: In addition to synoptic program, will take high-cadence (@20 mins)
C2 images in the equatorial band through at least Thursday. In this mode,
they have been seeing lots of interesting behavior, such as streamer 
twisting.

MDI: Continues continuous dynamics program of full-disk dopplergrams
and intensity filtergrams every minute, with 96-minute cadence full-disk
magnetograms.
