Solar flaring activity was quiet over past 24 hours with several C-class flares. The larger flare was a C8.2-class flare and was produced by the bipolar active region NOAA 3513 with a peak time at 21:01 on December 07. This region also produced several other C-class flares. The currently most complex region, NOAA 3511, with a beta-gamma magnetic class, was stable producing several C-class flares. C-class flares are expected in the next 24 hours with possible M-class flare from NOAA 3513 and possibly NOAA 3511.
No Earth directed coronal mass ejection was identified in the currently available SOHO/LASCO-C2 coronographe images.
A new mid-latitude south coronal hole has now reach the central median.
The Solar Wind (SW) conditions near Earth has returned to slow the solar wind regime. The SW speed ranged between 433 km/s and 526 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 remain in a slow solar wind regime in the next 24 hours.
Geomagnetic conditions were quiet with few short periods to unsettle conditions 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.
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.
The greater than 2 MeV electron flux, as measured by the GOES-16 satellite, went above 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.
Today's estimated international sunspot number (ISN): 115, based on 08 stations.
