10:32 UT W Limb Fairly fast ragged asymmetric front with cavity,
possibly residual to earlier halo event
11:30 UT S West Narrow ragged loop front, somewhat to S and slower
than previous event
12:55 - 17:54 UT Temporary data gap
23:54 UT N East Ragged front along diffuse streamer, gusty
outflow follows
