LASCO Activity Report for
January 18, 2007 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
2007/01/17 (Wednesday)
04:54 UT WS West 'Pair formation' (very faint) well above the C2
occulting disk. Difficult to give an exact time.
13:40 - 18:00 UT NO LASCO CME watch program due to special
C2 observation program (polar coronal hole/
plumes study in the SOUTH: orange filter at
100 sec exposure with a 5 minute cadence of
the upper paret of the FOV -1024x416-).
18:06 UT ES East Faint elongated loop-like front already under
development. It fades throughout C3.
20:30 UT EN East Diffuse and ragged loop-like front that fades
throughout C3, close to its inner edge. Some gusty
outflow.
2007/01/18 (Thursday)
00:54 UT NN East Very faint (apparently expanding) loop front. Not
discernible in C3.
01:31 UT WS West Initially bright and elongated feature that fades
throughout C3.
03:06 UT S Pole Faint loop front that fades throughout C3.
09:54 UT W Limb Ragged front.
Last C2 image available by the time of writing: 12:00 UT.
12:00 - 18:00 UT NO LASCO CME watch program due to special
C2 observation program (polar coronal hole/
plumes study in the SOUTH: orange filter at
