Points Of Interest

LASCO images severely degraded following the 
X18 proton flare from AR 0486 2003/10/28.
Proton levels now dropping but contamination
is still serious. 

LASCO images are at irregular times and cadences
due to the impact of the proton levels on the
instrument's telemetry buffer

02:30 UT  N West	Narrow spray

06:30 UT  N West	Fairly faint spray-like front

06:54 UT  S East	Narrow spray-like front, very faint

10:54 UT  HALO		The 'mother of all halos', bright loop front 
			in SE is extremely bright full halo CME by
			11:30 with much prolonged gusty outflow around
			most of occultor. X17.2 X-ray proton flare
			AR 0486 S20E10. Subsequent LASCO images
			severely degraded by ongoing proton storm
