Titolo: Aurora in arrivo?

Ieri (13/9/2000) c'è stata una bella CME (Coronal Mass Ejection) del
Sole con una notevole emissione di protoni.
Provate a visitare:

e

Ci sono quindi buon possibiltà di assistere nella notte tra il 14 e il
15 di un'aurora boreale anche sull'Italia.
Quindi occhi aperti
Peccato x la Luna piena.
Se non volete perdere l'aurora ed essere avvisati con SMS iscrivetevi ad

 Boh! Forse erano i panni stesi del piano di sopra?
Direi piuttosto che la colpa era del seeing. Osservavi dal balcone?

Si Si !
Comunque era una battuta per l'aurora comunque ero al balcone con il
telescopio ancora freddo diciamo così e bolliva tutto!!!!

O magari era una serata turbolenta (oops...o turbo...o lenta...come
dicevano al drive in...eheheh) di quelle che ti fanno rimpiangere di
non aver nessuno che ti metta via l'attrezzatura dopo che sei andato a
nanna...eehehhehe

         ** Major Solar Flare Associated CME is directed Earthward **
 ** Middle Latitude Auroral Activity Warning Issued for UTC day of 19 Sept
**
NOTICE:
     A major solar flare (x-ray class M5.9, optical size 2B [Brilliant in
hydrogen-alpha]) erupted from a rapidly developing sunspot region at 04:26
UTC on 16 September. This major flare was associated with a full halo
coronal
mass ejection that is directed Earthward. The Earth's magnetosphere is
expected to observe a nearly head-on collisional impact by this solar
disturbance sometime during the UTC day of 19 September. The impact of this
disturbance has the potential to produce some moderately strong levels of
auroral activity over the high and dark-sky middle latitude regions.
Although
this probably won't be a huge storm, it should be strong enough to permit
widespread observations of activity over many middle latitude regions.
     For North Americans, the time to begin watching for potential activity
will be during the early evening hours of 18 September (which coincides with
the early part of the UTC day of 19 September), and particularly during the
early morning hours of 19 September. There is a chance the arrival of this
disturbance may be too late for North American observers to spot very much
activity prior to morning twilight. If that occurs, the bulk of activity may
be observed over Russia, Europe and Australia/New Zealand. But there is a
slight chance activity may linger long enough to permit a few middle
latitude
observations during the evening hours of 19 September over North America.
     The phase of the moon on 18 and 19 September will still hamper attempts
to view the fainter details of auroral activity from the middle latitudes,
but its later rise times (near 11 pm local time) will permit the skies to
reach astronomically dark levels for about an hour or two prior to moonrise
in the evening hours of 18 and 19 September. Observations during the evening
and prior to about 1 am local time should be optimal for most regions, given
the rise-time and current phase of the moon.
     The active sunspot region which produced yesterdays major solar flare
is
beginning to show signs of decay, but may still be capable of producing an
additional major flare over the next several days.
