Points Of Interest
2007/06/15 (Friday)
00:30 UT S East A faint blob-like front starts to be discernible,
fading throughout C3. Another one at 04:06 UT.
06:06 UT S Pole Diffuse jet-like front toward SSW.
2007/06/16 (Saturday)
00:30 UT N West Blob-like front starts to be discernible ('pair
formation').
13:31 UT NN West Jet-like front that quickly fades.
20:30 UT S West Diffuse and relatively wide ragged loop front. WIDTH
in C3 at 01:42 UT (next day): ~ 45 deg. It fades
throughout C3.
2007/06/17 (Sunday)
06:30 UT W Limb Diffuse and wide ragged loop front with extremely
faint halo-like extensions that fade throughout C2.
The loop front is followed at 08:06 UT by a wider
expanding loop front that spans from NW up to almost
the S Pole (clockwise) by around 10:34 UT. The complex
event (in particular the second front) is too faint in
C3, where it fades already below 12 solar radii. X-ray
activity below A level, all along the day.
