UCMEO 93001 31118 2000/ 31118 60806 91242 0001/ 360// 223// 41175 31118 60736 90900 11803 10501 1112/ 99999 PLAIN BT LASCO and EIT observed a 'full' halo CME on 2003/11/18. A wide faint loop front was seen in C2 at 08:06 UT filling the SE quadrant but brightest in the S; at 08:26 UT this front had faint extensions up to the N pole. At 08:50 UT a second, much brighter, front appeared spanning ~160 deg from the SE to NW and with fainter extensions to the N pole. Thus between the two sets of fronts there was full coverage of the C2 occultor by 08:50 UT, albeit rather faint in the NE. The bright front first appeared in C3 images in the S at 08:42 UT and had developed to a full halo CME by 09:18 UT. The mean plane-of-sky speed was 1175 km/s, measured at PA 177 with possible evidence for slight acceleration. The CME was probably associated with complex activity in and around AR 0501 between 07:36 - 09:00 UT. EIT observed two flares between 07:36 - 08:00 UT and 08:12 - 09:00 UT. The first flare was centered at N03E18 and the second a little to the S and W. Additionally, a filament channel to the S and W of the active region was activated following the first flare and subsequently erupted. SEC records two flares, classed as M3.2 and M3.9, between 07:16 - 08:06 UT and 08:12 - 08:59 UT respectively, from AR 0498 located N00E18. Both an EIT wave and dimming were observed in association with this event. This event has therefore been determined frontsided. Images and movies will shortly be made available at ftp://ares.nrl.navy.mil/pub/lasco/halo/20031118 Best wishes, Gareth Lawrence. +----------PLEASE NOTE NEW EMAIL ADDRESS-----------+ Gareth Lawrence, grl@grace.nascom.nasa.gov SOHO-LASCO Operations Scientist, CUA, MC 682.3, Bldg 26, Rm 001, F: +1-301-286-0264 NASA Goddard Space Flight Center, Greenbelt, MD 20771.
