Solaraktive Regionen und Flares

Solar flaring activity was moderate over the past 24 hours, with 1 M-class flare identified. The largest flare was a M1.6 flare (SIDC Flare 6647) peaking on January 14 at 20:33 UTC, which was produced by SIDC Sunspot Group 740 (NOAA Active Regions 4321, 4341). A total of 5 numbered sunspot groups currently identified on the disk. SIDC Sunspot Group 740 (NOAA Active Region 4341) and SIDC Sunspot Group 760 (NOAA Active Region 4340) have currently Beta-Gamma magnetic configuration. SIDC Sunspot Group 763 (NOAA Active Region 4343) currently located at S10E15 has a Beta magnetic configuration and was growing over the past 24 hours. 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.

Koronaler Massenauswurf

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

Sonnenwind

Solar wind conditions have transited to fast solar wind conditions over the past 24 hours. The solar wind velocity gradually reaches 640 km/s, potentially linked to HSS from SIDC CH 137. The interplanetary magnetic field was around 5 nT, with the Bz reaching a minimum value of -6 nT. Solar wind conditions are expected to remain enhanced over the next 24 hours.

Geomagnetismus

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

Protonenflusswerte

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

Elektronenflüsse im geostationären 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 day. The 24h electron fluence was at moderate level and is expected to remain so in the next day.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 097, basierend auf 06 Stationen.
