# FAST WARNING 'PRESTO' MESSAGE  from the SIDC (RWC-Belgium)         #
#--------------------------------------------------------------------#
A series of CMEs were launched of which at least two were related to a prominence eruption starting at the southwest limb. SDO/AIA and PROBA2/SWAP data indicate that solar material starts to lift late September 29/early morning September 30 and part of it falls back south and another part falls to the north. The southern part produces a CME starting at 10:00 UT and shortly after that the NW part produces a CME as well. These two CMEs visually merge later on. The CMEs mainly propagate to the West with a speed of 330 km/s (CACTus estimate), but it is not excluded that a glancing arrives at Earth late October 4. 
The CME activity did cause a rise in the proton flux (at >10MeV) to about 1pfu, though the flux values have not reached the event threshold.

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.
