01:54 UT NN East Diffuse jet-like front developing toward NE.
15:30 UT WS West Bright ragged loop front. It fades throughout C3.
GOES reported a C2.1 X-ray flare on NOAA AR 10930
(S07W89) - with a rather impulsive initial ascending
flank - between 14:47 - 18:37 UT with peak emission
at 17:11 UT (see event reported to start at 16:06 UT).
16:06 UT WS West Bright loop front with apparently structured
interior. Difficult to give an exact time of first
appearance due to the superposition in the LOS with
previous event.

03:30 UT N West Diffuse jet-like front.
