Bulletin

Solar activity is low. NOAA AR 2390, which is rotating over the west limb, produced a C1.5 flare peaking at 20:05 UT on August 1. No large flares expected. The Earth is still under the influence of a fast speed solar wind stream emanating from a coronal hole. Solar wind speeds are around 600 km/s with interplanetary magnetic field magnitudes of 5 nT. Active conditions were observed overnight and more active periods can be expected in the next 24 hours.

Today's estimated international sunspot number (ISN): 054, based on 19 stations.
