Solar Active Regions and flaring

A total of 8 numbered sunspot groups were identified on the disk over the past 24 hours. Solar flaring activity was low over the past 24 hours, with only C-class flares recorded. The largest flare was a C3.4 flare peaking on November 27 at 16:44 UTC, which was produced by SIDC Sunspot Group 388 (NOAA Active Region 3976). SIDC Sunspot Group 383 (NOAA Active Region 3971) is the most magnetically complex region on disk with a beta-gamma configuration and has started to rotate over the west limb out of view. Solar flaring activity is expected to be moderate over the next 24 hours, with C-class flares expected and M-class flares likely.

Krooniaine massiline väljavool

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

Krooniauk

Returning SIDC Coronal Hole 82 (equatorial coronal hole with a positive polarity) and returning SIDC Coronal Hole 60 (mid-latitude coronal hole with a positive polarity) both began to cross central meridian on January 28.

Päikesetuul

Over the past 24 hours the Earth was under the slow solar wind regime. The solar wind speed ranged from 270 km/s to 330 km/s and the total interplanetary magnetic field ranged from 4 nT to 9 nT, with the Bz component reaching a minimum of -7 nT. The phi-angle was mainly in the negative sector (directed towards the Sun) with periods in the positive sector. The solar wind conditions can become disturbed in the next 24 hours due to the arrival of a CME that left the Sun on January 25th.

Geomagnetism

The geomagnetic conditions over the past 24 hours have been quiet to unsettled globally (Kp 1 - 3) and reached active conditions locally (K Bel 4). Active to minor storm conditions are expected for the next 24 hours.

Proton flux levels

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.

Electron fluxes at geostationary orbit

The greater than 2 MeV electron flux, as measured by the GOES-16 satellite, was above the threshold level from 14:10 UTC to 16:20 UTC on Jan 27. The electron flux is expected to remain below the threshold in the coming 24 hours. The 24h electron fluence is presently at normal level, and it is expected to remain so in the next 24 hours.

Today's estimated international sunspot number (ISN): 075, based on 04 stations.
