# FAST WARNING 'PRESTO' MESSAGE  from the SIDC (RWC-Belgium)         #
#--------------------------------------------------------------------#
There was a very faint halo coronal mass ejection (CME) first observed in LASCO imagery at 07:12 UT yesterday (2015-Aug-22). The CME was produced from active region (AR) 2403 (Macintosh:Ekc/Type:Beta-Gamma-Delta) at roughly 06:50 UT, and was accompanied by an M1.2 class flare and dimming. Although it is difficult to estimate the speed with which the CME is travelling toward the Earth in the absence of STEREO data, it is estimated that the CME has a speed of roughly 675 km/s, and is expected to arrive at the Earth on 2015-Aug-25 at 03:14UT with an error +/- 12 hours.

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.
