Aktywne obszary słoneczne i rozbłyski

A total of 9 numbered sunspot groups were identified on the disk over the past 24 hours. Solar flaring activity was moderate over the past 24 hours, with 1 M-class flares identified. This flare was a M2.69 flare peaking on November 27 at 08:10 UTC, which was produced by a region over the east limb in the northern hemisphere of the Sun. SIDC Sunspot Group 383 (NOAA Active Region 3971) is the most magnetically complex region on disk with a beta-gamma configuration. SIDC Sunspot Group 346 (NOAA Active Region 3961) has rotated over the west limb out of view. Solar flaring activity is expected to be moderate over the next 24 hours, with M-class flares very likely and a small chance for X-class flares.

Koronalny wyrzut masy

No Earth-directed Coronal Mass Ejections (CMEs) have been detected in the available coronagraph images.

Wiatr słoneczny

Over the past 24 hours the Earth was under the slow solar wind regime. The solar wind speed ranged from 270 km/s to 380 km/s and the total interplanetary magnetic field ranged from 1 nT to 7 nT, with the Bz component reaching a minimum of -3 nT. The phi-angle was mainly in the negative sector (directed towards the Sun). Similar slow solar wind conditions are expected for the next 24 hours.

Geomagnetyzm

The geomagnetic conditions over the past 24 hours have been quiet locally and globally (K BEL 1–2 and Kp 1–2). Quiet conditions are expected for the next 24 hours.

Poziomy przepływu protonów

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

Strumienie elektronów na orbicie geostacjonarnej

The greater than 2 MeV electron flux, as measured by the GOES-16 satellite, was below the 1000 pfu threshold level over the past 24 hours. However, greater than 2 MeV electron flux, as measured by the GOES-18 satellite, was slightly above the threshold level from 18:45 UTC to 22:40 UTC on Jan 26. The electron flux is expected to remain below the threshold in the coming 24 hours, though crossing the threshold level cannot be excluded. The 24h electron fluence is presently at normal level, and it is expected to remain so in the next 24 hours.
