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 at around 330 km/s in the past 24 hours. The periods of high speed observed yesterday by DSCOVR were not real, there was a problem with the data. The Interplanetary Magnetic Field is at about 5 nT.

Quiet to unsettled geomagnetic conditions were observed locally (K Dourbes between 0 and 3) and Kp ranged between 0 and 2 in the past 24 hours. Unsettled to active periods could occur in the coming 24 hours, due to high speed solar wind effects, although the faint/patchy nature of the coronal hole at the Sun may indicate that there will be no observable effect at the Earth.

Today's estimated international sunspot number (ISN): 000, based on 17 stations.
