LASCO Activity Report for
May 13, 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
SOHO Telemetry Submode changed to Submode 5 on 2004/04/13 at 16:00 UT
(SUMER began observing on 2004/04/14). SUMER campaign runs until 2004/06/17.
In other words, LASCO synoptic observation plan cadence remains the same
but the EIT CME watch images will be reduced to half-resolution (512x512)
during that period.
2004/05/12 (Wednesday)
00:06 UT W Limb Bright spray-like front brighter to S. It fades
throughout C3. It is followed by a couple of fainter
fan/spray-like fronts at: 02:26, 04:06, 05:26 UT.
06:26 UT ES East Very narrow ragged front. It fades throughout C2.
16:26 UT E Limb Diffuse front preceding a brighter structure at
~17:50 UT. Apparently twisted structure. It fades
throughout C3.
21:26 UT S West Blob-like front starting at around 3.5 solar radii.
Difficult to give an exact time of first appearance.
It fades throughout C3.
2004/05/13 (Thursday)
02:06 UT W Limb Faint elongated and diffuse front that fades throughout
C2.
02:26 UT ES East Very narrow ragged front that fades throughout C2.
05:50 UT E Limb Bright loop front preceded by a faint and diffuse front.
It is followed by another loop structure and twisted
trailing material. Faint signature of material being
swept away to N.
13:55 - 18:20 UT Temporary DSN Data Gap.
