Points Of Interest

2004/04/05

01:31 UT  W Limb	Spray-like front followed at 03:54 UT by another
			spray-like front.

02:54 UT  S East	Ragged loop front slightly to N of previous events. At 
			~04:06 UT it is followed by a brighter loop front at PA
			that matches that of its southern leg. At ~01:13 UT a
			CME is seen in EIT Fe XII running difference images 
			coming out from just behind the SE limb, while at
			~04:00 UT a fine prominence close to the SE limb is 
			seen to partially erupt.

06:06 UT  S East	Bright loop front, strong cavity, and trailing material.
			It surpasses previous event by the end of C2 FOV (07:31).
			By that time, faint extensions (shock signatures) can be
			seen to NE and SW giving the appearance of a partial 
			halo CME. Mean plane-of-sky speed at PA 145: 573 km/s
			based on C2 and C3 data. NOAA AR 0588 (located S18E35)
			produced an M1.7 X-ray flare starting at ~05:37 UT with
			peak emission at 05:55 UT. The flare is most likely
			related to the event.

19:31 UT  N West	Faint ragged blob-like front along streamer.	

21:08 UT  S East	Narrow ragged loop front in the trailing material of 
			event reported to start at 06:06 UT

2004/04/06

00:30 UT  W Limb	Spray-like front developing slightly toward SW, followed
			by a couple of ragged fronts (e.g., 04:54 UT, 09:30 UT).
			They all fade throughout C3.

06:06 UT  S Pole	Fairly faint and small spray-like front developing
			slightly toward SW. It fades throughout C2.

08:30 UT  S Pole 	Fairly faint and small spray-like front developing
			slightly toward SE. It fades throughout C2.
