Bulletin

Solar activity was quiet, featuring no C-class flares in the past 24 hours. AR NOAA 11835 has grown more complex and can produce C-class flares. Solar wind speed increased to around 450 km/s which is generated by a coronal hole connected to Earth on August 23d to August 25th. It was associated with a current sheet crossing. The interplanetary magnetic field Bz component reached values of around -10 nT which caused the geomagnetic conditions to reach minor storm levels. Currently the geomagnetic conditions are quiet and are expected to remain so for the next 48 hours. On the end of day 3 (August 30th) active conditions are expected due to a new coronal hole currently connected to Earth.

Today's estimated international sunspot number (ISN): 034, based on 13 stations.
