LASCO Activity Report for
April 5, 2005 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
- SOHO is in telemetry Submode 5 (since 2005/03/11 @ 15:00 UT).
- EIT 195 CME watch at half-res (512x512).
- Venus entered the C2 FOV from the right on 2005/03/24
(by around 16:00 UT). Now on the bottom left quadrant.
- Venus entered the C3 FOV from the right on 2005/02/26
(by the end of the day). Still visible.
2005/04/04 (Monday)
07:50 UT EN East Faint and elongated front. It fades troughout C3.
11:06 UT S Pole Diffuse loop front preceding a couple of bright
ragged loop fronts. Small ragged front on SE by
15:50 UT.
16:26 UT N West Kind-of "half" loop front. Another one starts to be
visible by 20:06 UT.
2005/04/05 (Tuesday)
06:50 UT W Limb Diffuse front that quickly fades.
09:26 UT N West Very faint and diffuse loop front. By 11:26 UT a
faint and expanding loop front starts to be
discernible at ~3.35 solar radii (PA ~315). A jet-
like front develops by 14:50 UT at a PA that matches
the PA of the northern leg.
12:50 UT S East Diffuse front preceding the development of a bright
loop front with apparently twisted interior. Gusty
outflow in the form of small ragged fronts precede the
whole event.
