03:30 UT E Limb Ragged loop front fades rapidly
04:30 UT W Limb Narrow loop front along streamer, fades,
some gusty outflow follows
10:34 UT W Limb Similar to previous event but wider
11:54 UT N East Wide bright ragged loop front with cavity and core
and much trailing material.
16:30 UT N West Slow ragged loop front, fairly narrow
20:06 UT N West Wider, faster well-defined loop front from
same/nearby region, breaks up through C2.
Some core-like material follows
20:06 UT Partial Wide bright fast front in SE is ~160 deg partial
Halo halo CME by 21:06. X3.4 flare in new AR (9767)
over SE limb, so backsided. 2170 km/s.

09:54 UT N West Fairly wide bright loop front with cavity and core
and some continued outflow
17:54 UT S West Small slow blob
18:30 UT N West Faster front with core follows and overtakes
slow loops. All fairly narrow
20:30 UT W Limb Wide bright loop front with cavity and core, much
gusty outflow follows. Streamers disrupted to N and S

02:30 UT S West Narrow ragged front along streamer
04:06 UT E Limb Very faint ragged front, fairly wide
15:06 UT S West Narrow ragged front breaks up through C2
22:30 UT S West Fairly wide bright fan develops into ragged
loop front. Soon obscured by
23:30 UT HALO Bright loop front in SW is full halo CME by
00:30. EIT backsided event, probably an
eruptive prominence
