large filament eruption across the central meridian

[Heiko]

A large filament eruption across the central meridian and stretching from the equator until almost halfway towards the north pole was observed beginning at about 06:30 UTC. An associated full halo CME was observed with the leading part seen above the northwest limb at 10:06 UTC in LASCO C2 images. The CME will likely impact Earth sometime between 15h UTC on February 1 and 09h UTC on February 2.

Lascofilm laeuft allerdings nicht recht.

Gibt's darueber noch mehr Info's ?

Subject: Full Halo CME on 2003/01/30, frontsided

LASCO and EIT observed a full halo CME on 2003/01/30. The
event was first observed in C2 at 09:39 UT as a ragged loop
front over the NW limb; by 10:06 UT separate bright loop
fronts were visible in the N, NW and S and by 11:39 it was
evident that they were all associated with the same event
and that emission could be seen around the entire C2
occulting disk, albeit faint in the E. The front first
appeared in C3 at 11:54 UT with full coverage of the C3
occultor by 12:54 UT. The mean plane-of-sky speed for this
event was 567 km/s at PA 355, with evidence for moderate
acceleration. Please note that as a result of the special
campaign to observe comet C/2002 X5 (Kudo-Fujikawa) the
start times are somewhat inaccurate.

The CME was probably most associated with an eruptive filament
observed by EIT between 06:13 - 09:33 UT, centered around N12W02
but exteding from ~N40E33 to ~S02W14 and possibly slightly more.
Neither an EIT wave nor dimming was observed in association with
this event. Note that the EIT cadence is slightly reduced from
normal around this time due to LASCO's comet observations.

Hallo,

hab mal flink 'ne Anim vom gestrigen CME erstellt. Die Sequenz (9 Bilder) erstreckt sich von etwa 11.00UT bis 19.30UT.
Komisch, dass das STD dazu noch nichts geschrieben hat. Sind die Bilder erst mit Verspätung online verfügbar gewesen?
Hab mir noch nicht die entsprechenden EIT oder H-alpha Bilder dazu angeschaut, aber wenn das Lasco-Team meint das Ding sehr wahrscheinlich erdgerichtet sei, dann wird das ja wohl hoffentlich auch stimmen.

Grüße
Peter
