LASCO Activity Report for
November 27, 2006 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
KEYHOLE (#15) Operations:
-------------------------
* 2006/11/24 - 2006/12/11: 26 m keyhole
* 2006/11/27 - 2006/12/08: 34 m keyhole
* 2006/11/25 - 2006/12/12: EIT Bakeout
* The TLM Keyhole #15 will have short daily passes and therefore limited
LASCO recorded data. Outside the periods of contact LASCO will go idle via
the on-board program.
* LASCO will observe in improved mode during TLM Keyhole #15 (C2 12 min
cadence, C3 30 min cadence with daily orange/blue pairs and pB if possible.)
2006/11/24 (Friday)
02:06 UT S West Fan-like front. By 04:06 UT, a very faint leg of
an apparently big expanding loop front starts to be
discernible on N West, reaching the N Pole by
~ 05:06 UT (barely discernible in C3).
06:30 UT N West Ragged front that fades throughout C2.
08:30 UT W Limb Diffuse ragged loop-like front. It fades close to the
inner edge of C3.
08:30 Ut ES East Diffuse front that quickly fades.
11:30 UT W Limb Diffuse ragged front developing slightly toward WNW.
12:30 UT W Limb Ragged loop front. It fades throughout C3.
19:31 UT S West Small front that quickly fades.
23:06 UT S West Small front with fainter extensions toward N. It
fades.
2006/11/25 (Saturday)
00:30 UT EN East Bright ragged front. It fades close to the inner edge
of C3.
00:30 UT N West Faint and diffuse asymmetric ragged front. Difficult
to give an exact time of first appearance.
03:54 UT W Limb Slow development of a system of faint ragged loop
fronts. Difficult to give an exact time of first
appearance. Pseudo-continuous outflow superposeed in
the LOS.
12:06 UT S Pole Faint and wide loop-like front. It fades throughout
C3.
21:31 UT S West Bright and very elongated loop-like front. It fades
throughout C3.
2006/11/26 (Sunday)
134:24 UT S West Diffuse ragged front that quickly fades. Another one
follows at 15:48 UT.
20:36 UT EN East Elongated loop front along streamer.
2006/11/27 (Monday)
04:00 UT S West Faint and diffuse loop-like front. Faint extensions
toward N.
Last C2 image available by the time of writing: 05:36 UT.
