Bulletin

Flaring activity remains at a low level. NOAA AR 2137 was numbered yesterday and shows flux emergence. This region, and NOAA AR 2135, produced flares at the high B-level in the past 24 hours. A C-class flare is possible from both regions. No earth-directed CMEs were observed since our last bulletin. We expect the current quiet geomagnetic conditions to persist in the coming days, with the chance for an isolated unsettled period (K=3). Unsettled to at most active geomagnetic conditions are possible starting August 13, under the influence of a small coronal hole that is currently passing the central meridian.

Today's estimated international sunspot number (ISN): 051, based on 07 stations.
