Bulletin

NOAA AR 2790 is the only visible active region on the solar disc, it did not produce any C-class flares or larger in the past 24 hours. A new region is rotating into view from the east limb. C-class flares are possible.

No Earth directed CMEs were detected in the past 24 hours.

The greater than 10 MeV proton flux is at background levels and is expected to remain at background levels. The greater than 2MeV electron flux did not exceed the 1000 pfu alert threshold, it is expected to remain so in the next 24 hours. The 24h electron fluence was at moderate levels, it is expected to remain so in the next 24 hours

The solar wind speed ranged from 450 km/s to 500 km/s with interplanetary magnetic field magnitude around 5 nT, in the past 24 hours. Bz was never below -5 nT. The fast solar wind from an equatorial patchy coronal hole may still affect the Earth in the next 24 hours.

Geomagnetic conditions were quiet to unsettled (local K Dourbes 0-3 and NOAA Kp 0-3). Geomagnetic conditions could increase in the next 24 hours, due to the arrival of high speed solar wind, otherwise quiet conditions are expected.

Today's estimated international sunspot number (ISN): 011, based on 05 stations.
