Halo CME Mail

Subject: Full Halo CME on 2003/11/06, backsided

Status: O

LASCO observed a full halo CME on 2003/11/06. A bright
full halo CME was first visible in C2 images at 17:30 UT;
a bright loop front was visible in in the S and E in C3 
images at 17:42 UT and had developed to a full halo CME 
by 18:18 UT.

EIT running difference images clearly show a major 
backsided eruption from 17:12 UT, with peak activity 
at 17:24 UT. This event has therefore been determined 

Note that the slight eastward asymmetry of this CME in
the C3 images is consistent with the likely position
of old AR 0484.

Best wishes,
	Gareth Lawrence.
