Solar Active Regions and flaring

There are seven visible active regions on the solar disk. Only C-class flaring has been observed in the last 24 hours, from NOAA ARs 3319, 3323 and a new active region rotating into view over the east limb. The strongest flare was a C8.9 from NOAA AR 3323, peaking at 03:49 UTC. In the next 24 hours, more C-class flares will be observed and M-class flares are possible.

Coronal mass ejections

No Earth-directed coronal mass ejections (CMEs) were detected in the past 24 hours.

Solar wind

In the last 24 hours the solar wind speed has been low, it is now around 320 km/s with an interplanetary magnetic field of about 7nT. Similar conditions can be expected for the next 24 hours.

Geomagnetism

The geomagnetic conditions over the past 24 hours have been quiet to moderate (K_Belgium and Kp up to 3). Similar conditions can be expected for the next 24 hours.

Proton flux levels

Over the past 24 hours the greater than 10 MeV GOES proton flux was at nominal levels and is expected to remain so in the next 24 hours.

Electron fluxes at geostationary orbit

The greater than 2 MeV electron flux was below the 1000 pfu threshold over the past 24 hours and is expected to remain so in the next 24 hours. The 24h electron fluence was at normal levels and is expected to remain at normal levels over the next 24 hours.

Today's estimated international sunspot number (ISN): 134, based on 12 stations.
