00:54 UT  S West	Thick wide fast bright loop front fills
			quadrant, fades through C2. Cavity, core 
			and arcades follow, prolonged gusty outflow
			including disconnection feature

08:06 UT  S East	Faint fast wide front

09:30 UT  N Pole	Narrow bright front along streamer

09:54 UT  S West	Bright blob/narrow front

13:31 UT  N East	Fairly bright ragged front

15:54 UT  W Limb	Bright wide 'spray' resolves to narrow front
			and fades in C2

05:30 UT  N West	Bright loop front emerges along bright streamer.
			CME follows around 18:30, arcades and fronts
			follow, and much gusty outflow

14:54 UT  S West	Prolonged narrow jet
