Points Of Interest

2004/01/29

04:54 UT  E Limb	Fast narrow ragged loop front brightest to N that
			surpasses a slow rising loop front. Barely visible
			in C3.

05:54 UT  S East	Fairly faint twisted (elongated) material.

05:54 UT  S West 	Extremely faint ragged spray front. It fades throughout
			C2.

16:06 UT  N East 	Slow rising loops' system ('helmet-like') along 
			streamer.

17:54 UT  E Limb	Bright 'jet-like' feature, though following a slightly
			curved path. It fades throughout C2. Gusty outflow.

23:54 UT  S East	Ragged loop front.

23:54 UT  N East	Very faint ragged and elongated loop front to S of
			streamer already at 5.6 solar radii.

00:06 UT  S West	Bright loop front with cavity and core preceded by 
			a very faint asymmetric ragged front. The LE of the
			loop front has a mean plane-of-sky speed of about 
			~450 km/sec (based on C3 data, at PA ~ 248). For more
			accuracy, the HT plot shows slight acceleration 
			(speed of ~350 km/s close to the inner edge, 
			~ 500 km/sec at  ~ 22 solar radii). Filament eruption
			observed on the SW quadrant of EIT/Fe XII images 
			starting at ~ 22:36 UT on previous day.
 
04:30 UT  S West	Another bright loop front with cavity and twisted core
			at PA coincident with that of southern leg of previous
			event. Prominence eruption seen in EIT Fe XII above SW
			limb starting ~ 02:12 UT.

06:06 UT  E Limb	Fairly faint loop front. It fades throughout C2.
