LASCO Activity Report for
July 01, 2004 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
SATURN entered the C3 FOV (from the left) on 2004/06/29 (Tuesday).
SOHO is now in a telemetry keyhole (2004/06/16 - 2004/07/03). LASCO data
will consist of typically two (occasionally three) continuous periods of
real-time data per day.
EIT 195 CME watch was interrupted on 2004/06/15 (Tuesday) at 15:00 UT
for EIT CCD bakeout calibrations. EIT CCD bakeout started on 2004/06/15
at ~ 20:00 UT. EIT CCD bakeout until 2004/07/04 (Sunday).
LASCO C2 and C3 will be in high cadence during the rest of the week:
C2 at a 12 minute cadence, C3 at the 30 minute cadence.
2004/06/30 (Wednesday)
02:24 - 05:24 UT Telemetry Data Gap.
06:00 UT W Limb Small ragged loop front.
07:36 - 11:12 UT Telemetry Data Gap.
11:48 UT W Limb Bright ragged loop front that fades close to the inner
edge of C3 FOV. It is preceded by a small ragged front.
17:24 UT N East Diffuse and faint loop front followed at 20:36 UT
(already under development after data gap) by a similar
front slightly to N. The second front moves apparently
faster than the first one in the C3 FOV and seems to
surpass the first front before fading.
18:48 - 20:36 UT Telemetry Data Gap.
20:57 UT N West Fairly faint ragged loop front already under development
after data gap. It fades throughout C2.
22:36 UT S West Ragged loop front that fades close to the inner edge
of C3 FOV.
2004/07/01 (Thursday)
01:24 UT E Limb Loop front with apparently twisted inner structure
preceded (surrounded) by a fainter and diffuse front
slightly ahead and to N moving faster. Both features
fade in C3.
05:48 UT W Limb Bright loop front with structured interior.
