LASCO Activity Report for
November 24, 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.)
2006/11/22 (Wednesday)
E Limb Gusty outflow in the form of small ragged blob-like
fronts (in particular at 00:30, 04:54, and 07:31 UT).
They can be seen since previous day, after the CME
reported to start at 05:30 UT.
03:30 UT S West Ragged elongated loop front. Diffuse extensions toward
N. It fades throughout C3.
08:30 UT S West Bright and elongated ragged loop front. It fades
throughout C3.
11:06 UT S West Bright ragged loop front. Gusty outflow all across
the W limb.
17:54 UT S West Initially bright ragged front that fades close to
the inner edge of C3.
19:54 UT S West Diffuse loop-like front a little bit to S of previous
event. It fades throughout C3.
23:06 UT S West Initially bright ragged front. It fades very close
to the inner edge of c3.
23:54 UT W Limb Faint loop-like front developing slower than previous
event. It fades throughout C3.
2006/11/23 (Thursday)
04:06 UT W Limb Diffuse loop-like front. It fades throughout C3.
09:54 UT S West Diffuse ragged front that fades throughout C2.
13:31 UT S West Bright loop front. Trailing material.
17:54 UT S West Small and elongated loop front in the trailing
material of previous event. Diffuse loop-like
extensions on W.
18:54 UT N Pole Diffuse jet-like front.
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.
Last C2 image available by the time of writing: 11:06 UT.
