Bulletin

Flaring activity has been very low, no C-class flares in past 24 h. The situation is not expected to change in the coming hours (the Sun is spotless).

Unsettled to active geomagnetic conditions were recorded on July 25, due to long lasting periods of negative Bz. Solar wind speed is currently at 360 km/s with interplanetary magnetic field magnitude of 4 nT. The arrival of a high speed stream from a northern coronal hole is possible in the coming 24 hours. In about 48 hours, other (equatorial) coronal hole will affect Earth. Active conditions expected.

Today's estimated international sunspot number (ISN): 000, based on 28 stations.
