Aktywne obszary słoneczne i rozbłyski

Solar flaring activity was low over the past 24 hours, with several C-class flares recorded. The largest flare was a C2.2 flare (SIDC Flare 6199), peaking on November 26 at 03:00 UTC, associated with SIDC Sunspot Group 705 (NOAA Active Region 4290; magnetic type alpha). There are currently five numbered active regions on the visible solar disk. SIDC Sunspot Group 706 (NOAA Active Region 4291; magnetic type beta-gamma-delta) is the largest and most complex active region but produced only low-level C-class flares. Low flaring activity was also produced by SIDC Sunspot Group 703 (NOAA Active Region 4288; magnetic type alpha) and SIDC Sunspot Group 707 (NOAA Active Region 4292; magnetic type beta). Solar flaring activity is expected to be low 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 identified in the available coronagraph imagery over the past 24 hours.

Wiatr słoneczny

Over the past 24 hours, solar wind parameters (ACE and DSCOVR) reflected the waning influence of a high-speed stream (HSS). The solar wind speed gradually decreased from about 830 km/s to 700 km/s. The interplanetary magnetic field remained weak, below 7 nT, and its southward component fluctuated between -6 nT and 6 nT. The magnetic field orientation was predominantly in the positive sector (field directed away from the Sun). Solar wind conditions are expected to remain slightly elevated over the next days under the continued influence of the high-speed stream.

Geomagnetyzm

Geomagnetic conditions were unsettled to active both globally and locally over Belgium (NOAA Kp = 3 to 4+; K-Bel = 3 to 4). Mostly unsettled to active geomagnetic conditions are expected over the next 24 hours.

Poziomy przepływu protonów

Over the past 24 hours the greater than 10 MeV GOES proton flux has been at nominal levels and is expected to remain at nominal levels over the next days.

Strumienie elektronów na orbicie geostacjonarnej

The greater than 2 MeV electron flux, as measured by GOES-18 and GOES-19, exceeded the 1000 pfu threshold over the past 24 hours. The electron flux is expected to continue exceeding this threshold over the next day. The 24-hour electron fluence was at normal to moderate levels and is expected to remain at moderate levels over the next day.
