Aktywne obszary słoneczne i rozbłyski

The solar flaring activity remained at low levels in the past 24 hours with rather low C-class flaring. The strongest activity was a C1.5 flare, peak time 03:17 UTC on Dec 27th, produced by the new simple unnumbered region near the south-east limb. The largest active region on the visible disc, NOAA AR 3529 (beta), has remained stable and quiet. NOAA AR 3528 (alpha) is now rotating behind the west limb and produced an isolated low C-class flaring, together with NOAA AR 3526 (beta). NOAA AR 3531 (beta) has shown slight reconfiguration, but remained quiet. The remaining regions have been stable and inactive. The solar flaring activity is expected to be at low levels over the coming days with probable C-class flares and low chances for M-class flaring.

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) were indicative of mildly enhanced slow solar wind conditions. The solar wind velocity smoothly varied in the range of 424 km/s to 540 km/s. The interplanetary magnetic field reached 7.2 nT with a minimum Bz of -5.3 nT. The B field was predominantly in the positive sector (directed away from the Sun). The solar wind conditions are expected to get elevated later on Dec 27th with possible glancing blow arrivals of two CMEs from Dec 24th.

Geomagnetyzm

The geomagnetic conditions over the past 24 hours were globally quiet and quiet to unsettled locally over Belgium with a single unsettled period at noon on Dec 27th. Quiet to active geomagnetic conditions are expected in the next 48 hours with small chances for isolated minor storms. Mostly quiet conditions are expected on Dec 29th.

Poziomy przepływu protonów

Over the past 24 hours the greater than 10 MeV GOES proton flux was at background levels and is expected to continue so over the next days.

Strumienie elektronów na orbicie geostacjonarnej

The greater than 2 MeV GOES 16 electron flux was below the 1000 pfu threshold and is expected to remain so in the upcoming days.The 24h electron fluence was at nominal level and is expected to remain so in the next days.
