# FAST WARNING 'PRESTO' MESSAGE  from the SIDC (RWC-Belgium)         #
#--------------------------------------------------------------------#
The Cactus halo CME alert sent out on November 8 01:49 UT concerns the CME related to the X flare from region 2205 with peak at 17:25 UT, November 7.
In SOHO/LASCO C2 coronagraph images it is first clearly visible around 18:08 UT, but the actual onset is missed due to a 30 minute data gap just before. It is a partial halo CME directed to the north-east with angular width of at least 180 degrees. Cactus, however, wrongly included high speed components in the south-western direction and hence reported as full halo. Projected speeds are around 600 km/s. The event is also captured in STEREO A/COR 2 images.
The bulk of the mass is expelled in north-eastern direction (off the Sun-Earth line) but a possible glancing blow may be expected late November 10, though the effects are not expected to be strong.

CCMC Rules of the Road: CCMC requests that users notify the CCMC, CME model/technique developers and submitting forecasters/researchers before performing event and validation studies with data from the CME Arrival Time Scoreboard. It is recommended that such studies be performed with the knowledge and collaboration of developers and submitting forecasters/researchers.
