# FAST WARNING 'PRESTO' MESSAGE  from the SIDC (RWC-Belgium)         #
#--------------------------------------------------------------------#
A partial halo CME was detected by SOHO/LASCO on June 19, first appearing in the LASCO C2 field of view at 19:24 UT (first frame after a long data gap). The CME had the angular width of around 190 degrees and projected plane-of-the-sky speed of around 400 km/s. The CME was produced by the eruption of a filament to the north of the Catania sunspot groups 89 and 90 (together constituting the NOAA AR 2093), starting around 14:25 UT as seen by SDO/AIA. The eruption was also accompanied by coronal dimmings and a post-erution arcade. It was followed by a perhaps related C4.0 flare peaking at 19:24 UT in the Catania sunspot group 90. This flare was, in turn, accompanied by a narrow CME first appearing in the LASCO C2 field of view at 19:48 UT. This narrow CME is not expected to arrive at the Earth. An interplanetary disturbance associated with the partial halo CME is expected to arrive at the Earth late on June 23 or early on June 24, most probably only with a glancing blow. It may!
 result in active to perhaps minor storm geomagnetic conditions. The partial halo CME was a far side event from the perspective of Venus, so it will not arrive at Venus.

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.
