Points Of Interest
2005/02/04 (Friday)
03:08 UT ES East Diffuse front that quickly fades. Afterward, slow
development of a system of loops. By 06:30 UT, another
diffuse front can be seen developing superposed in the
LOS (not discernible in C3). Connection to event
reported to start at 07:31 UT on NE ???
07:31 UT N East Diffuse and ragged loop front expanding toward N. It
fades throughout C3. Some outflow afterward.
21:30 UT N West Faint, diffuse, and not-well-defined front that
quickly fades.
2005/02/05 (Saturday)
00:54 UT EN East Small blob-like front along streamer.
01:31 UT S East Faint loop front that fades close to the inner edge
of C3.
07:31 UT E Limb Faint, diffuse, and not-well-defined front partly
superposed in the LOS with the slow development of
a system of loops started on previous day at ~
06:30 UT). It is later apparently surpassed by
following event.
13:31 UT ES East Bright and big loop front. Trailing material. Gusty
outflow well into next day.
18:30 UT E Limb Bright and elongated ragged loop front. Some
infalling material in the tail. By 20:58 UT, the
development of a faint loop front toward ESE can be
discerned in the trailing material of event reported
to start at 13:31 UT.
2005/02/06 (Sunday)
05:30 UT N West Extremaly faint though relatively big expanding loop
front. Barely visible in C3.
09:54 UT E Limb Faint and small front that fades throughout C2.
15:06 UT S East Elongated and ragged structure. By 16:30 UT, a ragged
loop front can be discerned superposed in the LOS
developing a little bit more slowly.
19:31 UT WS west Elongated and ragged loop front.
2005/02/07 (Monday)
03:30 UT WS West Ragged front followed at 08:30 UT by a spray-like
front.
