LASCO Activity Report for
July 15, 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
SATURN is still in the C3 FOV (Western hemisphere) after reappearing from
behind the C3 occultor on 2004/07/10 (Saturday) at ~ 05:42 UT.
2004/07/14 (Wednesday)
03:30 UT N East Kind of thick jet-like front followed by a diffuse
and asymmetric ragged loop front whose northern leg
matches the apparent PA of the jet. They quickly fade.
05:06 UT N East Initially bright front develops as a ragged faint
structure with faint extensions to S. It fades in C2.
06:30 UT W Limb Apparently twisted elongated structure, preceded by a
kind of spray to N. It fades throughout C3. Couple
of veru faint and diffuse fronts follow at ~08:30 and
~11:30 UT.
12:54 UT N West Kind of blob-like front.
14:30 - 15:52 UT LASCO Data Gap (due to ICAL01:
Intercalibration for EIT with CDS).
18:54 UT W Limb Faint spray.
21:30 UT WS West Faint, diffuse and elongated loop front. It fades in C3.
2004/07/15 (Thursday)
00:30 UT W Limb Faint and very narrow expanding loop front, followed
at 04:54 UT by a slightly brighter spray developing
slightly toward WSW.
02:30 UT S East Initially bright and narrow front along streamer
accompanied by a faint and diffuse loop front to S.
Very faint extensions also above the E Limb. The event
fades quickly in C2 and is barely visible in C3
(toward SW). GOES recorded and X1.8 X-ray flare from
NOAA AR 0649 (S09E51) between 01:30 - 01:48 UT with
peak emission at 01:41 UT.
11:30 UT S West Diffuse jet front just starting.
