N West Much gusty outflow all along the day starting after the backsided 'full' halo CME on previous day. 00:30 UT S East Very narrow ragged loop front. 00:54 UT S West Faint asymmetric loop front extending up to above W limb, immediately after the narrow ragged loop front reported to start at 23:30 UT on previous day. It fades throughout C3. 09:54 UT S West Ragged (spray-like) loop front. Gusty outflow well into next day. 11:06 UT E Limb Ragged front (spray like). It fades in C3. It is followed at 14:30 UT by a very narrow ragged loop front (to S) and at 15:54 UT by a faint spray-like front, both fading very close to the inner edge of C3 FOV. 12:54 UT N East Faint asymmetric loop front. It fades in C3. 20:06 UT N West Ragged front preceding the slow development of structured feature (*). 21:30 UT E Limb Ragged loop front developing slightly toward SE, fading in C3.
00:30 UT N West (*) Slow development of structured (twisted) feature. Difficult to give an exact time of first appearance. 05:54 UT N East Bright loop front. 10:54 UT S East Ragged loop front. 11:30 UT S West Ragged front.
