Solar Active Regions and flaring

Solar flaring activity was low over the past 24 hours, with only C-class flares identified. The largest flare was a C9.6 flare peaking on January 14 at 03:50 UTC, originated from SIDC Sunspot Group 761. A total of 3 numbered sunspot groups are currently on the disk. SIDC Sunspot Group 761 (Alpha magnetic configuration) just turned on disk from the east limb and is responsible of the majority of the C-class flaring. Solar flaring activity is expected to be moderate over the next 24 hours, with C-class flares expected and M-class flares likely.

Coronal mass ejections

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

Solar wind

Solar wind conditions are transitioning to slow solar wind conditions over the past 24 hours. The solar wind velocity gradually decreased from 590 to 470 km/s. The interplanetary magnetic field was around 6nT, with the Bz reaching a minimum value of -4 nT. Solar wind conditions are expected to remain slow over the next 24 hours.

Geomagnetism

Geomagnetic conditions were quiet to unsettled globally and locally (Kp 3-, K bel 2) over the past 24 hours. Quiet to unsetled geomagnetic conditions are expected over the next day.

Proton flux levels

The greater than 10 MeV proton flux remained below the 10 pfu threshold and is expected to remain so over the next days.

Electron fluxes at geostationary orbit

The greater than 2 MeV electron flux was above the 1000 pfu threshold for the past 24 hours and is expected to remain so in the upcoming days. The 24h electron fluence was at moderate level and is expected to remain so in the next days.

Today's estimated international sunspot number (ISN): 063, based on 07 stations.
