LASCO Activity Report for
June 7, 2005 SOHO Science Daily Meeting
Planner: K. Schenk, G. Stenborg
Event times are first frame seen in C2 camera unless otherwise noted.
These are preliminary observations for the daily SOHO science discussions.
Final analysis is reported on the Lasco CME list.
An archive of these reports is available.
Points Of Interest
- Couple of Kreutz comets on C2 since late on 2005/06/06 moving from the
South toward the Sun. The fainter one vanishes on 06/07 by ~ 03:48 UT,
and the other one by ~ 05:12 UT. The bigger one (the one to the right)
was first detected in C3 at about 04:00 UT on 06/06.
* Telemetry KEYHOLE (SOHO will stay in TM Submode 5 during the Keyhole):
2005/06/05 - 2005/06/25: 26 m
2005/06/09 - 2005/06/20: 34 m
* During the KEYHOLE, LASCO will be in synoptic program at the usual
cadences, with little loss of telemetry throughout due to the advanced
recorder setup.
* 2005/05/06 - 2005/06/24: EIT Bakeout (==> No EIT CME Watch).
EIT performed the long pre-bake calset (06/06 15:58-21:45 UT) and went
to heaters on at 21:52 UT. EIT will be in bake till June 24 @ 10:00 UT
and should resume imaging by (06/24) 20:00 UT.
2005/06/06 (Monday)
05:06 UT E Limb Initially bright and ragged loop front that fades very
close to the inner edge of the C3 FOV. Kind of
reconexion event occurs in its trailing material.
Afterward, by around 08:06 UT, a ragged blob-like front
starts to move out (it fades throughout C3).
11:06 UT E Limb Very faint ragged loop fronts developing slightly
toward ENE. Gusty outflow.
16:26 UT SS East Very faint elongated loop front rotating toward SSW as
it develops. Extremely faint in C3.
2005/06/07 (Tuesday)
02:00 UT EN East Ragged front along streamer.
02:36 UT E Limb Diffuse and ragged elongated loop front.
05:12 - 12:48 UT Temporary DSN data Gap.
12:48 UT N East Bright loop front followed by nice prominence material
(brighter than the loop front) already under development
after data gap.
Time of the last C2 image analyzed: 14:12 UT.
