Bulletin

No active regions visible on the Sun. No flares observed, nor expected.

No Earth directed CMEs in past 24 h. Solar protons have remained at background levels over the past 24 hours.

The solar wind speed is at 360 km/s with interplanetary magnetic field magnitude of 3 nT. Quiet conditions have been observed in the past 24 h. Geomagnetic activity will remain quiet until the high speed solar wind from a negative polarity equatorial coronal hole arrives to the Earth on August 1 (mostly active conditions expected then).

Today's estimated international sunspot number (ISN): 000, based on 23 stations.
