2001/09/19

02:54 UT  N East	Initially narrow blob-like feature widens
			to a faint front through C2. 

03:54 UT  N East	Well-defined loop fronts fill large part 
			of quadrant, fairly bright. Arcades follow
			towards N extremeity by 07:31. Slower loops
			follow. All S of previous event

07:31 UT  S West	Fast wide bright front spans ~140 deg by 
			08:30. Cavity, core in S West, then numerous 
			prolonged arcades. Probably backsided,
			maybe from AR9608?

08:30 UT  N Pole	Very faint front

15:30 UT  S East	Bright ragged front along streamer, disrupts
			nearby streamer

19:31 UT  E Limb	Wide fairly faint front, brightest in S East.
			Possibly residual from or connected to previous
			event 

2001/09/20

00:30 UT  N East	Bright loop front fills quadrant. Spans ~150 deg
			by 03:30


05:30 UT  E Limb	Bright streamer disrupted, slow front leads
			slow loops and bright core over E limb. 
			Slightly faster faint loop front extends 
			down over E limb. Prolonged outflow

	05:30 - 08:30 UT	Data gap - unrecoverable

08:30 UT  N East	Bright front along streamer, already in
			progress. Prolonged outflow including 
			arcades
