Bulletin
Solar activity was very low with flaring restricted to B-class flares. All regions have a simple configuration (alpha or beta). NOAA active region 2396 showed some fast growth. A backsided filament eruption was followed by a slow, small CME with first measurement in LASCO-C2 at 13:25 UT. No Earth-directed CMEs were observed. Chances for strong flares remain low.
The solar wind speed has gradually decreased to 440 km/s. Geomagnetic conditions were mainly quiet and are expected to remain so.
Today's estimated international sunspot number (ISN): 082, based on 17 stations.Solar indices for 03 Aug 2015
