LASCO Activity Report for
October 14, 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



2004/10/13 (Wednesday)

00:30 UT  N Pole	Very faint and diffuse elongated front developing
slightly toward ENE.  

00:30 UT N West Extremely faint elongated and ragged loop front.

03:54 UT N East Big loop front followed at 11:06 UT by a jet-like
front that quickly fades.

08:06 UT W Limb Thin spray-like front.

15:30 UT W Limb Very faint elongated loop front. Difficult to give
exact time of first appearance.  

20:30 UT E Limb Very slow development of a twisted (rather cicular)
structure. It is very difficult to give an exact
time of first appearance duu to its slow development.
  
21:55 UT N West Kind of 'explosive' ragged front. Expanding loop-like
structures following, well into next day. Bright
elongated feature on S West (followed by a faint,
diffuse, and apparently twisted elongated structure).
Very faint halo extensions above the N Pole and
Eastern hemisphere by 22:30 - 23:30 UT. The extensions
fade throughout C2.
Please note that GOES reported by the time a couple
of X-ray flares on NOAA AR 0682 (not likely related
to the event on NW):
- a B2.2 X-ray flare (S17E61) between 21:08 - 21:17 UT
with peak emission at 21:14 UT, and
- a C1.0 X-ray flare (S16E63) between 21:20 - 22:20 UT
with peak emission at 22:06 UT.

2004/10/14 (Thursday)

00:30 UT  ES East	Small and bright ragged loop front, most likely related
  two the 2 flares mentioned in previous paragraph (in
event at 21:55 UT on previous day). Some trailing
material. Gusty outflow to N. The event develops
superposed in the LOS with the circular twisted
structure reported at 20:30 UT (previous day), moving
much faster. By 06:54 UT the circular structure is
close to the end of C2 FOV.

Last image analyzed taken at 11:06 UT.
