00:54 UT N West Bright asymmetric front with cavity and small
bright core. Some arcades and cross-hatching
04:30 UT N West Prominence material (seen in EIT) barely
discernible from above event's outflow
08:30 UT E Limb Fairly fast bright loop front with cavity
and some arcades
11:54 UT N West Loops begin to brighten and rise along streamer
over an ~18 hr period. Plentiful arcades and
cross-hatching by end of day
15:30 UT E Limb Faint nebulous front with cavity
15:54 UT W Limb Faint loop fron quickly overtaken by
16:30 UT W Limb Wide bright multiple-loop front with cavity and
helical core. Much gusty outflow including some
small disconnection features
16:54 UT N East Bright loop front fills most of quadrant.
Cavity and arcades follow, streamer to N
disrupted. Some gusty outflow
17:30 UT S Pole Sequence of fairly bright loop fronts eventually
followed by small dimmer core and cross-hatching

00:30 UT N West Bright loop fronts emerge along streamer. Further
S than 11:54 event from 6/4. Cavity, arcades and
cross-hatching all follow. Streamer begins to
brighten ~3 hrs earlier
04:30 - 10:30 UT Temporary data gap
