Aktywne obszary słoneczne i rozbłyski

Solar flaring activity was moderate over past 24 hours with two M-class flares and several C-class flares. The two M5.4 and M1.5 class flares were produced by the most complex region, NOAA 3511, with a beta-gamma magnetic class. The flares peak time were at 23:07 UTC on December 08, and at 09:55 UTC on December 09 respectively. This region also produced several C-class flares. The other region, NOAA 3510 and NOAA 35011 also produced several C-class flares. C-class flares are expected in the next 24 hours with some chances of M-class flare from NOAA 3511 and possibly also from NOAA 3513.

Koronalny wyrzut masy

Several coronal mass ejections associated with filament eruptions were observed in the available SOHO/LASCO-C2 coronographe. However, those coronal mass ejections are expected to miss Earth. The large halo coronal mass ejection detected by the SIDC/CACTus tool in SOHO/LASCO-C2 coronographe images at 16:24 UTC on December 08 was determined to be back sided. Another halo coronal mass ejection associated to a large filament eruption was observed at 03:56 UTC on December 09. The analysis is ongoing, however, no Earth-directed component has been identified so far.

The mid-latitude south coronal hole with a positive polarity has crossed the central median.

Wiatr słoneczny

The Solar Wind (SW) conditions near Earth show a slow solar wind regime. The SW speed ranged between 404 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 -3.7 nT and 4.4 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.

Geomagnetyzm

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 slow solar wind conditions.

Poziomy przepływu protonów

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.

Strumienie elektronów na orbicie geostacjonarnej

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 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.
