NOTE:
----
Multiple B-class X-ray activity was reported by GOES all along the day. In 
addition, NOAA AR 10960 produced three M-class flares: an M1.0 peaking at 
06:51 UT, an M2.8 at 14:59 UT (S08E78), and an M2.1 at 21:52 UT (S09E82). 
It also produced a C2.9 x-ray flare at 22:22 UT.

07:30 UT  E Limb	Diffuse ragged front superposed with a ragged loop 
			front (wider), which apparently moves more slowly 
			and fades throughout C2. The diffuse front fades
 			throughout C3.

22:30 UT  N West	Faint and difffuse front expanding toward N. Very faint
			in C3. 

23:54 UT  ES East	Bright elongated loop front. WIDTH in C3 at 04:18 UT
			(next day): ~ 25 deg. 

2007/06/02 (Saturday)

NOTE:
----
Multiple B-class X-ray activity continues all along the day. In addition,
NOAA AR 10960 produced a couple of M-class X-ray flares: an M2.5 peaking at
06:11 UT, and an M1.0 at 10:35 UT.

03:54 UT  W Limb	Bright concave feature. By 04:30 UT, an elongated
			ragged front can be discerned in WNW moving apparently
			faster. Difficult to disentangle the series of events
 			(see also event reported to start at 22:30 UT on
 			previous day).

17:30 UT  N West	System of expanding loop fronts, well into next day.
 			Also on WNW, an elongated loop-like front (slightly
 			brighter). Both features fade throughout C3.

NOTE:
----
Multiple B-class and C-class X-ray activity continues all along the day. In
addition,NOAA AR 10960 produced three M-class X-ray flares: an M2.4 peaking 
at 01:59 UT (S10E68), an M7.0 at 02:12 UT (S08E70), and an M4.5 at 06:41 UT
(S06E63).

06:54 UT  E Limb	Diffuse loop front that quickly fades.

09:54 UT  E Limb	Initially bright loop front. WIDTH in C3 at 12:18 UT:
			~ 25 deg.
