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 380 km/s with interplanetary magnetic field magnitude of 3 nT. Quiet geomagnetic conditions were observed in the past 24 h. Disturbed geomagnetic conditions (up to minor storm levels) are expected when the high speed solar wind from a positive polarity equatorial coronal reaches the Earth in August 5.

Today's estimated international sunspot number (ISN): 000, based on 14 stations.
