LASCO Activity Report for
February 16, 2005 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
2005/02/15 (Tuesday)
S East Some ragged and not-well-defined loop fronts all along
the day.
04:06 UT W Limb Faint ragged front. Infalling material. Difficult to
give an exact time of first appearance. It fades
throughout C3.
05:06 UT E Limb Extremely faint jet-like front followed at 07:54 UT by
a very narrow spray-like front. Both features develop
slightly toward ENE. By 08:30 UT, a faint ragged front
can be discerned to S, in the aftermath of the gradual
event reported on previous day.
10:54 UT WS West A small blob-like front start to be discerned already
half way to the end of the C2 FOV, fading throughout
C3.
20:30 UT E Limb Jet-like front developing slightly toward ENE.
20:30 UT W Limb Very faint and diffuse wide loop front extending all
the way to SW. By 20:58 UT, a diffuse loop front
develops above the S Pole. They both are barely
visible in C3. GOES reported a C1.1 X-ray flare on
NOAA AR 10734 (practically at the center of the disk)
between 19:28 - 20:05 UT with peak emission at 19:48 UT.
2005/02/16 (Wednesday)
04:30 UT E Limb Elongated and diffuse faint loop-like structure. It is
followed at 06:54 and 08:06 UT by a couple of similar
fronts, all of them developing slightly toward ENE.
They all fade very close to the inner edge of C3.
06:54 UT S West System of faint and diffuse expanding loop fronts.
Time of last C2 image analyzed: 13:31 UT.
