Final analysis is reported on the Lasco CME list.
An archive of these reports is available.
Points Of Interest
2008/01/04 (Friday)
EN East Pseudo-continuous outflow.
09:30 UT EN East Very ragged (not-well-defined) front. Faint
expanding extensions toward N by 10:30 UT
(past the N Pole by 13:54 UT; by that time
the expanding extension meets the northern
leg of a system of loops developing since
earlier on NNW -difficult to give an exact
time of first appearance-).
2008/01/05 (Saturday)
EN East Some pseudo-continuous outflow along the
day.
2008/01/06 (Sunday)
03:30 UT S East Very narrow and elongated spray-like front
immediately followed (03:54 UT) by a very
narrow and elongated loop (jet-like) front.
04:30 UT N Pole Very narrow and elongated loop (jet-like)
front.
05:30 UT NN West Diffuse fan-like front that quickly fades.
Note:
----
EIT 195 images show a wave with origin on NOAA AR 10981 (N27, past
the central meridian), propagating toward NW, N, W between - 16:00 -
17:24 UT (first EIT wave of the new solar cycle). There are no
visible signatures of the event in the LASCO coronagraphs.
2008/01/07 (Monday)
02:54 UT S East Jet-like front.
03:30 UT NN West Faint and diffuse expanding loop front
preceding the development of an elongated
loop front.
Last C2 image available by the time of writing: 14:30 UT
