Solar Active Regions and flaring

Solar flaring activity was low over the past 24 hours, with only C-class flares identified. The largest flare was a C2.1 flare (SIDC Flare 3798) peaking on March 10 at 20:32 UTC, which was produced by SIDC Sunspot Group 428 (NOAA Active Region 4019). A total of 5 numbered sunspot groups were identified on the disk over the past 24 hours. SIDC Sunspot Group 428 (NOAA Active Region 4019) is the most complex active region (Beta-Gamma-Delta). Solar flaring activity is expected to be low over the next 24 hours, with C-class flares very likely and a chance for M-class flares.

Krooniaine massiline väljavool

No new Earth-directed Coronal Mass Ejections (CMEs) have been detected in the available coronagraph images.

Päikesetuul

Slow solar wind conditions were recorded over the past 24 hours. The interplanetary magnetic field was between 4 and 6 nT, with the Bz reaching a minimum value of -5 nT. Slow solar wind conditions are expected in the next 24 hours.

Geomagnetism

Geomagnetic conditions were globally and locally quiet to unsettled (Kp 3 and K Bel 3). Quiet conditions are expected in the next 24 hours.

Proton flux levels

The greater than 10 MeV proton flux remained below the 10 pfu threshold and is expected to remain so over the next days.

Electron fluxes at geostationary orbit

The greater than 2 MeV electron flux was above the 1000 pfu threshold and is expected to remain close to that thresholds in the upcoming days. The 24h electron fluence was at nominal level and is expected to remain so in the next days.

Today's estimated international sunspot number (ISN): 132, based on 07 stations.
