太陽活動區和耀斑

Solar flaring activity was moderate over past 24 hours with two M-class flares and several C-class flares. The two M1.0 and M2.3 class flares were produced by the complex region, NOAA 3511, with a beta-gamma magnetic class. The flares peak time were at 13:19 UTC on December 09, and at 03:53 UTC on December 10 respectively. This region also produced several C-class flares. The other region, NOAA 3510 and NOAA 3513 also produced several C-class flares. C-class flares are expected in the next 24 hours with some chances of M-class flare from the two beta-gamma magnetic class regions: NOAA 3511 and NOAA 3513.

日冕物質拋射

No Earth directed coronal mass ejection was identified in the currently available SOHO/LASCO-C2 coronographe images.

日冕洞

The mid-latitude south coronal hole with a positive magnetic polarity has crossed the central median. A new equatorial coronal holes with positive magnetic polarity is on the East side of the solar disc facing Earth.

太陽風

The Solar Wind (SW) conditions near Earth continue to show a slow solar wind regime. The SW speed ranged between 370 km/s and 460 km/s, the total interplanetary magnetic field (Bt) was below 5.0 nT. The North- South magnetic component (Bz) ranged between -4.2 nT and 3.5 nT. The interplanetary magnetic field phi angle was negative (directed towards the Sun) during the past 24 hours. The mid-latitude south coronal hole with a positive magnetic polarity that has crossed the central median on December 07 may slightly affect the SW conditions in the next days. Globally we do expect that the SW conditions remain mostly in a slow solar wind regime in the next 24 hours.

地磁

Geomagnetic conditions were quiet both globally and locally (NOAA-Kp and K-BEL 1 to 2) during the last 24 hours. We expect mainly quiet conditions in the next 24 hours in response to the slow solar wind conditions.

質子通量水平

The greater than 10 MeV proton flux was at nominal levels over the past 24 hours and is expected to remain so for the next 24 hours.

地球靜止軌道上的電子通量

The greater than 2 MeV electron flux, as measured by the GOES-16 satellite, was ranging around the 1000 pfu alert threshold during the last 24 hours due to the past fast solar wind conditions. It is expected to remain close to 1000 pfu during the next 24 hours. The 24h electron fluence was at moderate levels during the past 24 hours and is expected to remain at these levels for the following 24 hours.
