Data badly degraded due to ongoing proton storm

17:30 UT S West Ragged front along streamer followed by slow loops and some arcades2001/09/22
06:06 UT W Limb Initially narrow bright front widens through C2. Numerous arcades follow 10:34 UT N West Fairly wide bright front with fainter extension over N Pole. Some gusty outflow in N West 18:30 UT W Limb Bright front, part of residual outflow from 06:06 event? Similar speed2001/09/23
12:06 UT N East Bright ragged front along streamer follows slow loops 13:30 UT S East Sequence of faint loop fronts, also narrow loops to N 14:30 UT E Limb Bright loop front, quite fast, with small bright kotted core 17:06 UT S Pole Faint loop front over S Pole. These last four events create impression of a wide slow partial halo but some are backsided 20:30 UT HALO Bright front over W Limb had fainter extensions around disk and is a full halo event by 21:30 and possibly at 20:30, hard to tell amongst earlier outflow. Fastest in N and much faster than earlier events. Most probably backsided 21:54 UT S East Fairly wide bright front maybe extends up to NE and SW. Hard to tell with all other outflow. Most probably backsided2001/09/24
02:54 UT W Limb Faint loop front, another at 08:30 04:54 UT N Pole Very faint blob/narrow front 10:30 UT HALO Thick wide bright very fast front in S East is full halo CME by 10:54. Core-like material and some arcades follow in S East. Probably associated with CME and subsequent X2.6 flare in AR9632 at S18E27 C2 ratio movie C3 ratio movie 18:00 - 23:59 UT Data too badly degraded to identify any activity or events2001/09/25
00:00 - 10:30 UT Data too badly degraded to identify any activity or events 10:39 UT - present Temporary data gap
