LASCO Activity Report for
April 4, 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).
- Venus entered the C3 FOV from the right on 2005/02/26
(by the end of the day). Still visible, by the time just
below the C3 occulting disk.
2005/04/01 (Friday)
07:50 UT W Limb Very faint and diffuse narrow loop front. It fades
throughout C2.
15:50 UT N East Faint and diffuse elongated loop front. It fades
throughout C2.
20:50 UT E Limb Another faint and elongated loop-like feature that
fades throughout C2.
2005/04/02 (Saturday)
00:06 UT N Pole Diffuse an elongated loop-like feature developing
toward NNW.
00:50 UT W Limb Diffuse and faint elongated loop-like feature followed
by a very faint ragged front that starts to be
visible at ~ 4 solar radii (PA ~ 250, @ 02:50 UT).
12:06 UT S West Ragged and elongated loop front with structured
interior. System of loop fronts in the trailing
material.
2005/04/03 (Sunday)
00:26 UT N East Jet-like front that quickly fades.
00:50 UT N Pole Faint and diffuse front developing toward NNW. It
quickly fades.
00:50 UT S West Very narrow and elongated loop-like feature. By 01:50
UT, a diffuse and narrow loop-like front develops to
N. They both fade throughout C2.
2005/04/04 (Monday)
07:50 UT EN East Faint and elongated front.
11:06 UT S Pole Diffuse loop front preceding a couple of bright
ragged loop fronts.
Last C2 image analyzed: 13:27 UT.
