Bulletin

Solar activity is expected to be eruptive with C class flares likely from NOAA ARs 1817 and 1818. There remains a small risk for an isolated M class flare to occur in one of these two regions. A CME was associated with the M1.5 flare of Aug. 13, but coronagraphic data suggest that the bulk of the CME is essentially going southward, and that it will miss the Earth. We expect mostly quiet geomagnetic conditions for the next 24 hours, and then unsettled to active conditions by the end of Aug. 14, due to a coronal hole becoming geoeffective.

Today's estimated international sunspot number (ISN): 077, based on 13 stations.
