# FAST WARNING 'PRESTO' MESSAGE  from the SIDC (RWC-Belgium)         #
#--------------------------------------------------------------------#
The partial halo CME, first seen in the SOHO LASCO C2 field of view at 14:48 UT on August 12, was associated with the long duration B7.0 flare and the filament eruption from the south-west quadrant. The CME had the angular width of about 210 degrees and the projected plane of the sky speed of about 500 km/s (as reported by CACTUS software package).  
The glancing blow from the CME-driven shock wave, associated with the partial halo CME, might be expected to arrive at the Earth in the early morning of April 16.

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.

If you are looking for the official U.S. Government forecast for space weather, please go to NOAA's Space Weather Prediction Center (https://swpc.noaa.gov). This "Experimental Research Information" consists of preliminary NASA research products and should be interpreted and used accordingly.
