The first of two events today, 2000/09/15.
Faint full HALO CME event. Observed in both
EIT and LASCO instruments.

LASCO and EIT observed two (2) full halo CMEs today, 2000/09/15. Using
the NOAA coding there will be two separate alert messages.
The first event was visible in C2 at 11:50 UT as a faint loop front with
material at all position angles. The speeds through the C2 and C3 fields
averaged to 377 km/second, measured at PA 209 degrees.
EIT observed a flare at 11:00-11:24 UT near disk center at location [N14;
E2.2]. GOES shows a C9.5 X-ray flare at 10:51 UT from AR9165. 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:
