LASCO Activity Report for
November 26, 2004 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 2004/11/08 @ 22:15 UT. While in Submode 5,
half resolution EIT 195 CME watch (512x512).
2004/11/24 (Wednesday)
03:26 UT S East Kind of 'reconexion' event (blob-like front going out
and another one falling down). Difficult to give an
exact starting time. Separation point: ~ 4 solar radii
at PA ~ 110 deg. More infalling material to N.
03:50 UT N West Faint loop front developing toward WNW. It fades
throughout C2. An elongated and narrow feature
develops by the time at roughly the PA of the northern
leg of the loop front. This feature can be followed
in C3 only close to the inner edge.
04:26 UT S West Faint elongated and expanding loop-like feature
developing slowly. Difficult to give an exact time
of first appearance.
08:26 UT E Limb Diffuse ragged loop front that fades throughout C2. It
seems to be preceded at 07:27 UT by a a very diffuse and
narrower front right above the E Limb. Couple of
slightly brighter fronts follow (also narrower than
the first one mentioned) starting at 09:50 and 12:06 UT.
12:50 UT N East Initially bright loop front develops along streamer. It is
followed by another loop front developing similarly, not as
bright, at 17:06 UT. Another one at 20:06 UT.
18:06 UT E Limb Narrow ragged loop front. Couple more a little bit to N by
19:50 UT and 20:54 UT. The development of the last two ones
show very faint loop-like extensions to N, that seems to
connect with the corresponding loop fronts developing along
the streamer at 17:06 and 20:06 UT (see entry at 12:50 UT).
19:50 UT WS West Very faint and small front developing toward W that quickly
fades.
22:06 UT E Limb Faint and diffuse loop front preceding at 23:26 UT on NE
(at roughly the PA of its northern leg) a ragged looop front
along the streamer, and a narrow ragged loop front on E at
00:26 UT on next day. As in previous case, this narrow loop
front on E would seem to be connected by faint extensions to
the loop along streamer.
2004/11/25 (Thursday)
02:26 UT E Limb Narrow ragged loop fronts continue developing. Another ones
at 04:50 UT and 06:26 UT.
05:50 UT S West Very faint loop front is seen to start development at couple
of solar radii above the limb.
11:26 UT N east Bright loop front with some twisted trailing material.
