Aktywne obszary słoneczne i rozbłyski

Solar flaring activity was moderate during the past 24 hours with an M1 flare from NOAA Active Region (AR) 3500 (magnetic configuration Beta-Gamma, Catania group 65) detected yesterday at 21:20 UTC. Most of the frequent C-class flaring activity was emitted from NOAA AR 3500 and NOAA AR 3492 (magnetic type Beta, Catania group 58). C-class flaring activity is highly expected in the next 24 hours. Isolated M-class flares are possible and there is a small chance of an X-class flare.

Koronalny wyrzut masy

A partial halo Coronal Mass Ejection (CME) can be seen in LASCO-C2/SOHO images starting from yesterday 22:12 UTC. It is likely to be geo-effective and arrive at the first half of 5 Dec. A partial halo CME that can also been seen in LASCO-C2/SOHO images as lunched yesterday 03:12 UTC is associated with a flare on the west solar limb and is not expected to be geo-effective.

Wiatr słoneczny

The Solar Wind (SW) conditions are in the process of returning to a typical slow SW regime. The SW speed gradually dropped from 540 km/s to 450 km/s during the last 24 hours. The total interplanetary magnetic field (Bt) dropped from 27 nT during the height of the disturbance to 5 nT. The North-South magnetic component (Bz) varied between -19 and 27 nT during the Coronal Mass Ejection (CME) arrival, but it has lately stabilised to around 5 nT. The interplanetary magnetic field phi angle was predominantly directed towards the Sun during the past 24 hours. The SW conditions are expected to be affected by another CME arrival in the next 24 hours.

Geomagnetyzm

Geomagnetic conditions dropped from moderate storm conditions (NOAA Kp and K BEL 6) yesterday at 12:00-15:00 UTC to quiet conditions (NOAA Kp 2, K BEL 1) today at 09:00-12:00 UTC. They are expected to increase again to active or minor storm conditions in the next 24 hours as a result of the expected arrival of another Coronal Mass Ejection (CME).

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, was below the 1000 pfu alert threshold during the last 24 hours and is expected to to remain below this threshold 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.
