Points Of Interest
2007/04/27 (Friday)
12:06 UT NN West Diffuse and very faint jet-like front.
2007/04/28 (Saturday)
WN West Some 'pair formation' events along the day.
03:34 UT S Pole Jet-like front developing toward SSW.
06:26 UT W Limb Elongated and bright thin loop-like front, followed at
09:06 UT (a little bit to S) by a fan-like front
(which quickly fades). It fades throughout C3, close
to its inner edge.
10:06 UT W Limb Initially bright ragged (elongated) loo front,
followed at 11:50 UT by a slightly wider ragged loop
front with diffuse and very faint extensions to N and
S. It fades throughout C3, also close to its inner
edge.
23:50 UT NN East Jet-like front.
2007/04/29 (Sunday)
01:27 UT NN West Jet-like front.
01:27 UT S East Very thin and elongated fan-like front preceding
an elongated loop-like front.
01:50 UT WN West 'Pair formation' (blob-like front coming out and
counterpart falling down).
14:26 UT WN West Diffuse ragged front. It fades in C3, close to its
inner edge.
17:06 UT WN West Small ragged front with faint and diffuse expanding
extensions around that seem to extend up to SW. They
fade throughout C3.
21:26 UT SS West System of faint expanding loop fronts. Difficult to
give an exact time of first appearance. Barely
discernible in C3.
