LASCO Activity Report for
June 10, 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
* 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
* SOHO Maneuvers: 2005/06/17
* During the KEYHOLE, LASCO will be in synoptic improved program (12 min
cadence C2, 30 min cadence C3), 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.

02:00 UT S West Extremely faint and diffuse front develops as a faint
and diffuse loop front. It fades throughout C2.
04:00 UT S Pole Diffuse jet-like front developing slightly toward SSE.
05:12 UT WN West Very faint and diffuse front. Difficult to establish
its association (if any) with next two following events.
It fades throughout C2.
05:12 UT ES East Very faint ragged front that fades throughout C2.
06:00 UT S East Fainter (than previous event) expanding loop-like front.
It also fades throughout C2.
14:24 UT EN East Faint expanding loop front [1].
. By that time, a very diffuse front develops above
the W Limb [2].
. By 15:48 UT, an expanding ragged front can be seen
developing above the N Pole.
. By 16:24 UT, another expanding and ragged loop front
starts to be discernible above the E Limb [3].
C3 shows:
. a diffuse loop front on WSW [2] (first seen at 15:18
UT) that quickly fades,
. a diffuse and expanding front on NE [1] (first seen at
15:42 UT), and
. another expanding front on NE first seen at 19:42 UT
[3] (note that there is a C3 data gap betwen 16:42 -
19:42 UT).
GOES reported:
. a C1.5 X-ray flare on NOAA AR 10775 (N07E13) between
13:28 - 14:23 UT with peak emission at 13:34 UT,
. a C1.0 X-ray flare on NOAA AR 10776 (S07E18) between
16:28 - 16:34 UT with peak emission at 16:31 UT, and
. a B8.7 X-ray flare on NOAA AR 10776 (S06E18) between
16:54 - 17:01 UT with peak emission at 16:58 UT.

03:24 - 13:00 UT Temporary DSN Data Gap.
S West Gusty outflow after data gap.
Time of the Last C2 Image analyzed: 15:04 UT.
