LASCO Activity Report for
December 01, 2004 SOHO Science Daily Meeting

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

After the EIT Shutterles Campaign and while in Submode 6, EIT 195 CME 
watch at full resolution (1024x1024).

SOHO Telemetry Submode changed to Submode 6 at 14:00 UT on 2004/11/30 
(EIT Shutterless Campaign between 17:00 - 19:40 UT). It will be back 
to Submode 5 on 2004/12/01 at 19:00 UT.

SOHO is in Telemetry Submode 5 since 2004/11/08 @ 22:15 UT. While in 
Submode 5, half resolution EIT 195 CME watch (512x512).

2004/11/30 (Tuesday)

07:27 UT  N East	Bright ragged loop front. By 07:50 UT, a narrow and 
			asymmetric ragged feature can be discerned on ENE (at
			roughly the PA of the southern leg of the big loop
			front). GOES reported a C4.8 X-ray flare from NOAA AR
			10708 (N09E33) between 06:32 - 07:22 UT with peak
			emission at 06:58 UT. By 11:26 UT a faint ragged loop
			front can be discerned developing toward NNE in the 
			trailing material of the event (fading throughout C3).
			Also by that time, on ENE, a faint an asymmetric
			expanding loop front seems to develop. Please note that
			GOES also reported a C1.8 X-ray flare from NOAA AR 10707
			(S13W05) between 10:54 - 11:06 UT with peak emission at
			11:02 UT, though it is difficult to establish any
			association to the C2 events described above.

	16:51 - 20:01 UT	LASCO Data Gap 
				(EIT Shutterless Campaign 17:00 - 19:40 UT)

20:01 UT  NN West	Faint loop front followed by what looks like a system of
			thin loops apparently extending all above the western
			hemisphere.
		
22:33 UT  N East	Small jet-like front that quickly fades.

2004/12/01 (Wednesday)

02:29 UT  S West	Faint asymmetric front.

04:53 UT  NN East	Jet-like front.

07:53 UT  NN East	Bright ragged front immediately followed by a ragged 
			loop front that extends up to above the N Pole. GOES
			reported an M1.2 X-ray flare from NOAA AR 10708 (N07E20)
			between 06:53 - 07:55 UT with peak emission at 07:20 UT.
			EIT 195 images show a strong brightening at 07:13 UT
			above the aforementioned AR followed by a rather circular
			intensity disturbance with epicenter in the AR.

	14:50 - 18:50 UT	Temporary DSN Data Gap.
