LASCO Activity Report for
June 10, 2003 SOHO Science Daily Meeting
Planner: K. Schenk, G. Lawrence
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
LASCO doors will close 2003/06/10 ~15 UT ahead
of spacecraft maneuvers. Re-opening expected
2003/06/13 ~15 UT. EIT runs at high cadence
in the meantime
Bright Kreutz comet presently visible in C2 images
2003/06/09
11:30 UT N West Fairly wide bright loop front with cavity
and bright structured core, follows very
slow loops along streamer. M4.7 X-ray
flare AR 0375, N11W29. Gusty outflow well
into following day including slow loop
fronts and loops leading to partial
streamer blowout
11:54 UT N East Faint amorphous front, faint loop
fronts follow
13:31 UT S East Faint ragged blob-like front, slight cavity
18:54 UT W Limb Slow loop front/loops along southern
extremity of 11:30 event, quite bright
23:06 UT N West Narrow bright loop front, within/near outflow
from 11:30 event but faster and brighter
2003/06/10
00:54 UT S Pole Narrow front fades rapidly
01:31 UT E Limb Narrow asymmetric loop front with slight
cavity, quite bright, some outflow
03:54 UT S Pole Ragged front, faster wider and brighter
than 00:54 event
05:54 UT N East Ragged loop front along streamer,
quite faint and slow
06:06 UT HALO Extremely faint ragged front in SE is full
halo CME by 06:30. Fairly fast event is
generally faint except in NE and NW in
projection with existing material. Possibly
same event as 05:54, too little data at
writing to establish either way. No clear
EIT or X-ray counterpart so probably
backsided (maybe old AR 0365?)
06:54 - ~13:30 UT Temporary DSN data gap
