# FAST WARNING 'PRESTO' MESSAGE  from the SIDC (RWC-Belgium)         #
#--------------------------------------------------------------------#
A partial halo CME was observed by LASCO/C2 (CACTUS) starting at 07:12UT (30 July). It had a speed of about 600 km/s and an angular width of at least 180 degrees. This CME was related to the filament eruption in the northeast quadrant that took place earlier today (30 July, between 04:30-05:30UT). The LASCO imagery confirmed earlier findings from STEREO-images that the bulk of this CME is directed to the north and away from Earth. However, due to the angular width, a glancing blow from this CME can not entirely be ruled out. Hence, this CME may affect the geomagnetic environment around noon on 2 August. Currently, at most active geomagnetic conditions are expected.

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.
