太陽活動區和耀斑

Solar flaring activity was moderat over past 24 hours with an M-class flare and several C-class flares. The M2.3-class flares was produced by the bipolar active region NOAA 3513 with a peak time at 22:01. This egion also produced several C-class flares. The currently most complex region, NOAA 3511, with a beta-gamma magnetic class, was stable producing several C-class flares. The other region, NOAA 3507, also produced C-class flares. C-class flares are expected in the next 24 hours with some chances of M-class flare from NOAA 3513 and possibly NOAA 3511.

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

A new mid-latitude south coronal hole has now reach the central median.

太陽風

The Solar Wind (SW) conditions near Earth remained affected by the High-Speed Stream (HSS) from the large equatorial coronal hole that crossed the central meridian on Saturday 2 of December. The SW speed decreased from 628 km/s and 478 km/s, the total interplanetary magnetic field (Bt) was below 5.0 nT. The North-South magnetic component (Bz) ranged between -3.6 and 3.5 nT. The interplanetary magnetic field phi angle was negative (directed towards the Sun) during the past 24 hours. The SW conditions are expected to returned to a slow solar wind regime in the next 24 hours.

地磁

Geomagnetic conditions were mainly quiet to unsettle both globally and locally (NOAA-Kp and K-BEL 1 to 3) during the last 24 hours. We expect mainly quiet conditions in the next 24 hours in response to the return of 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, went above the the 1000 pfu alert threshold during the last 24 hours due to the ongoing fast solar wind condition. It is expected to remain close to 1000 pfu during the next 24 hours. The 24h electron fluence was at low levels during the past 24 hours and is expected to remain at these levels for the following 24 hours with also some increases due to the ongoing solar wind conditions.
