03:30 UT  S East	Brightening just appearing in SE developes as a wide
			(faint) ragged loop front toward ESE. It is followed 
			by a brighter ragged loop front on ESE at 05:54 UT 
			(with faint extensions spanning up to the S Pole). GOES 
			recorded an A6.5 X-ray flare on S08E18 between 02:45 -
			03:45 UT with peak emission at 03:05 UT. 

Note:
----
An impulsive C2.0 X-ray flare follows on NOAA AR 10969 -S06E41- (between 
07:49 - 07:58 UT with peak emission at 07:54 UT).

00:30 UT  EN East	Very diffuse loop front. 

05:54 UT  WN West	Brightening just appearing develops as an elongated 
			loop front with a fan-like top.

19:54 UT  SS West	Extremely faint asymmetric loop front.
