LASCO Activity Report for
January 20, 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.
2006/01/19 (Thursday)
00:30 UT WS West Big and bright loop front (brighter to N) with inner
core.
01:31 UT ES East Elongated fan-like front that fades close to the inner
edge of C3.
09:30 UT N East Diffuse brightening develops as an elongated loop front.
Pseudo-continuous loop fronts developing afterward
rotating toward the N Pole and up to NNW by the
beginning of next day.
09:30 UT S East Brightening along streamer immediately followed by a
bright loop front, which starts to be seen at around
10:06 UT. Very bright and big core follows slightly
shifted to S (prominence material). The event starts
to be seen in C3 at 11:18 UT developing as a ragged
loop front with a bright inner core. Some faint
extensions can be seen to N, extending up to almost NE.
Gusty outflow follows well into next day. EIT 195
images show the lift-off of a very large prominence
between 09:36 - 11:36 UT, which appears to originate
well behind the limb.

S East Strong gusty outflow continues. 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.
Last C2 image available by the time of writing: 15:06 UT.
