Points Of Interest
Kreutz sungrazing comet SOHO 299(TBC) (discoverer: M. Boschat) in C2
field of view, prior to data gap. It can be seen at ~6.6 Rs at PA 126

17:06 UT Halo Thin front initially bright fades in C2, over N Pole
from PA 350 to 50. Fainter extensions to ~PA160 and
very faint over S and W. Plane-of-sky speed to
~18 Rs about 638 km/s with significant deceleration.
C9 flare in AR 9394 peaks around 17:00

00:26 UT W Limb Slow bright ragged front along narrow faint
streamer. Prolonged outflow includes cross-hatching
05:50 UT N East Faint ragged front/fan followed by flux ropes
12:50 UT W Limb Faint loop(s)
13:50 UT E Limb Highly irregular blob resolves to Y-type
disconnection feature in C2. Brightest feature
on faint loop front, cavity follows
15:26 UT N East Wide jet/ragged front along streamer
20:50 - 23:50 Temporary data gap
23:50 UT N East Similar to 15:26 event but wider and brighter.
Gusty outflow follows
