Aktywne obszary słoneczne i rozbłyski

Solar flaring activity was at low levels, with several C-class flares recorded in the past 24 hours. The largest flare was a C5.5 flare (SIDC Flare 2772) peaking at 16:22 UTC on December 01, associated with SIDC Sunspot Group 323 (NOAA Active Region 3906; beta- gamma). There are currently five numbered active regions on the visible disk. SIDC Sunspot Group 323 (NOAA Active Region 3906) was the main driver of the flaring activity observed over the past 24 hours. Low flaring activity was also produced by SIDC Sunspot Group 305 (NOAA Active Region 3912; beta-gamma). Other regions on the disc have simple configuration of their photospheric magnetic field (alpha and beta) and did not show any significant flaring activity. The solar flaring activity is expected to be at low levels over the next 24 hours, with C-class flares very likely and a chance for M-class flares.

Koronalny wyrzut masy

No Earth-directed coronal mass ejections (CMEs) have been detected in the available coronagraph imagery over the past 24 hours.

Wiatr słoneczny

Over the past 24 hours, the solar wind parameters (ACE and DSCOVR) reflected near-slow solar wind conditions. The solar wind speed ranged between 410 km/s and 470 km/s. The interplanetary magnetic field remained below 9 nT. The southward component of the interplanetary magnetic field fluctuated between -5 nT and 6 nT. The interplanetary magnetic field orientation was predominantly in the positive sector (field directed away from the Sun). Slow solar wind conditions are expected to prevail during the next days, with a chance of a weak enhancement on Dec 02 due to possible arrival of a high-speed stream from a positive polarity coronal hole, that started to cross the central meridian on Nov 28.

Geomagnetyzm

Geomagnetic conditions over the past 24 hours were quiet to unsettled both globally and locally over Belgium (NOAA Kp: 1 to 3, K-Bel: 1 to 3). Quiet to unsettled geomagnetic conditions are expected over the next 24 hours.

Poziomy przepływu protonów

The greater than 10 MeV GOES proton was below the 10 pfu threshold over the past 24 hours. It is expected to remain below the threshold level over the next 24 hours.

Strumienie elektronów na orbicie geostacjonarnej

The greater than 2 MeV electron flux, as measured by the GOES-16 satellite, remained below the 1000 pfu alert threshold, and it is expected to remain below the threshold during the next 24 hours. The 24h electron fluence was at normal levels and is expected to remain at these levels.
