太陽活動區和耀斑

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.

日冕物質拋射

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

太陽風

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.

地磁

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

質子通量水平

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

地球靜止軌道上的電子通量

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.
