E Limb Gusty outflow all along the day.
02:30 UT E Limb Ragged front in the trail of event reported to start
at 18:53 UT on previous day.
04:30 UT E Limb Another ragged front (brighter than the previous one).
12:50 UT N East Ragged blob-like front starts to be discernible in
the gusty outflow.
18:30 UT E Limb Wide ragged loop front. Not-well-defined leading edge
by the time the event reaches the end of the C2 FOV.
By 20:30 UT, extremely faint and diffuse extensions can
be guessed above the N Pole. The event is barely
discernible in the C3 FOV (and only close to its
inner edge). GOES reported a C2.9 X-ray flare on
NOAA AR 10956 (N01E35) between 17:19 - 17:53 UT with
peak emission at 17:41 UT.
