LASCO Activity Report for
January 23, 2006 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
Mercury can be seen now in the C3 FOV, in the southern hemisphere, moving
from right to left. It is expected to be in the C3 FOV until around Feb 2.

S East Strong gusty outflow continues jointly with some small
ragged fronts. Also by the beginning of the day the
slow development of a system of faint loops starts to
be distinguished superposed in the LOS with the gusty
outflow.
09:30 UT W Limb Faint jet-like front that quickly fades.
16:54 UT S East While the outermost front of the slow system of faint
loops gets to the outer edge of the C2 FOV, a very
faint and diffuse expanding front starts to be guessed,
spanning up to past the S Pole by midnight (difficult
to give an exact time of first appearance). By around
02:30 UT on next day, one leg of the front reaches the
W Limb while the other seems to remain anchored on SE
(very asymmetric shape).

S East Gusty outflow continues. Some small (blob-like) ragged
fronts at: 08:06, 10:56, 18:54, and 23:06 UT.
18:30 UT W Limb Extremely faint loop front. It fades throughout C3.
2006/01/22 (Sunday)
04:30 UT S East Small (blob-like) ragged front.
13:54 UT WS West Faint ragged front starts to be discernible. It fades
throughout C3.
23:06 UT WS West Couple of small and extremely faint fronts start to be
discernible.
2006/01/23 (Monday)
04:30 UT S West Very faint and elongated loop-like front.
10:54 UT WN West Ragged loop front.
Last C2 image available by the time of writing: 11:06 UT.
