LASCO and EIT observed two (2) full halo CMEs today, 2000/09/15. Using
the NOAA, ISES CME coding there will be two separate alert messages.

The second event was visible in C2 at 15:06 UT as a faint loop front with
material at all position angles.  The speeds through the C2 and C3 fields
averaged to 467 km/second, measured at PA 220 degrees.

EIT observed a flare at 14:36-15:00 UT near disk center in AR 9165 at
location [N14;  E2.2]. GOES shows a M2 X-ray flare at 14:29 UT from AR
9165. This flare is probably associated to the HALO CME event seen in
LASCO.

Images and Movies are available of both events today for your enjoyment at
the LASCO ftp server:
