Bulletin

There is no active region on the visible Sun. No B or brighter flares in the past 24 hours, none expected.

No Earth-directed Coronal Mass Ejections (CMEs) were observed in available coronagraphic imagery.

The greater than 10 MeV proton flux was at nominal levels in the past 24 hours, and is expected to stay at nominal levels in the next 24 hours.

Solar wind speed near Earth has remained around 310 km/s in the past 24 hours. The Interplanetary Magnetic Field ranged between 1 and 6 nT.

Quiet geomagnetic conditions were observed (K Dourbes and Kp between 1 and 2) in the past 24 hours. Quiet conditions expected for the next 48 hours.

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