Bulletin

Solar activity has been low with no C-class flares in the past 24 hours. There is a very small chance for a C-class flare from AR NOAA 11835. Solar wind speed is at around 340 km/s and the interplanetary magnetic field Bz component increased to around -7 nT. Geomagnetic conditions where quiet and are expected to remain so for the next 48 hours. A new coronal hole is connected to Earth with possibly a fast solar wind stream and this will result in a current sheet crossing. The estimated arrival time of this high speed stream is around August 30th and might result in active geomagnetic conditions.

Today's estimated international sunspot number (ISN): 040, based on 15 stations.
