LASCO Activity Report for
December 15, 2004 SOHO Science Daily Meeting

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 # 7: 2004/12/13 - 2004/12/29

- EIT pre-bake cals taken on Saturday 2004/12/11 between 15:24-18:30 UT. The 
  CCD bakeout started at 18:47 UT. The end of the bakeout will be on 2004/12/28
  at 10:00 UT. Therefore, no EIT images during that period.

- During the Keyhole, LASCO will observe with DSN gap recording availability
  thanks to the FOT and the SOCs hard work. C2 and C3 will observe at a 
  standard synoptic plan of C2 at 10 minute cadence and C3 at the 30 minute
  cadence with the daily pB and flat field images.

SOHO Telemetry Submode is in Submode 5.

00:48 UT  N East	Bright loop front with twisted trailing material.

02:48 UT  S West	Pair formation. Separation point at ~ 3.7 solar radii
			(PA ~ 233). Please note that by about 00:12 UT (though
			difficult to give an exact time) a very faint loop 
			front begins to be discerned preceeding the pair. The 
			loop can be seen in C3 almost until the data gap.
