LASCO Activity Report for
May 13, 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

May 12-14: IPS Measurements. During the IPS study, EIT will have regular
synoptics along with half resolution 195 CME watch.

On 2005/05/03 @ 19:06 UT SOHO Telemetry Submode changed to Submode 6.
It will be in Submode 6 until 2005/05/16 @ 12:00 UT. During that time,
EIT 195 CME watch at full resolution (1024x1024).


2005/05/12 (Thursday)

03:52 UT  E Limb	Jet-like front.

04:52 UT  WN West	Diffuse and ragged front that fades throughout C2.

	06:22 - 11:22 UT	NO LASCO C2 Data due to IPS "C3 only" 
				timeframe.

14:22 UT  S West	Diffuse loop front that fades throughout C2.

17:52 UT  NN West	Expanding diffuse loop front. It fades throughout C3.

21:52 UT  N Pole	Jet-like front developing slightly toward NNW.

23:22 UT  E Limb	Wide and diffuse fan-like front.

23:22 UT  NN West	Diffuse loop front developing like pushed toward S. 

2005/05/13 (Friday)

	04:52 - 09:52 UT	NO LASCO C2 Data due to IPS "C3 only" 
				timeframe.

17:22 UT  All around	Nice and bright Full Halo CME. GOES reported a long
			duration X-ray event (M8.0) from NOAA AR 10759 
			(N12E11) between 16:13 - 17:28 UT with peak emission 
			at 16:57 UT. EIT images show the presence of an EIT
			wave and dimming. A proton event follows.

	17:50 - 22:50 UT	Non-recoverable LASCO Data Gap (C2 times)
				due to LEB (LASCO Electronic Box) crash.
