Güneş Aktif Bölgeleri ve parlama

Solar flaring activity was low over the past 24 hours, with only C-class flares identified. A total of 6 numbered sunspot groups were identified on the disk over the past 24 hours. SIDC Sunspot Group 693 (NOAA Active Region 4284) (Beta magnetic configuration) was the most active region over the past 24 hours, but only producing C-class flaring. The largest flare was a C9.9 flare (SIDC Flare 6135) peaking on November 19 at 09:53 UTC was from behind the east limb. Solar flaring activity is expected to be low over the next 24 hours, with C-class flares very likely and a small chance for M-class flares.

Koronal Kütle Atılımı

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

Koronal delikler

SIDC Coronal Hole 137 (mid-latitude coronal hole with a negative polarity) has finished it’s crossing of the central meridian. The influence of the associated high speed stream is expected to impact Earth during Nov 21 2025.

Güneş rüzgarı

Slow solar wind conditions were recorded over the past 24 hours. The interplanetary magnetic field was around 8 nT, with the Bz reaching a minimum value of +1nT. The solar wind velocity were around 400 km/s. Solar wind conditions may become slightly enhanced in the next 24 hours, in case of the arrival of the High speed stream associated with the SIDC coronal hole 136.

Jeomanyetizma

Geomagnetic activity was globally and locally quiet to unsettled over the past 24 hours. Geomagnetic conditions are expected to remain quiet to unsettled in the next 24h.

Proton akı seviyeleri

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

Jeostatik yörüngedeki elektron akıları

The greater than 2 MeV electron flux measured by GOES 18 and GOES 19 remained below the 1000 pfu threshold. Electron flux levels are expected to remain below the 1000 pfu threshold over the next 24 hours. The 24-hour electron fluence remains at normal levels and is expected to remain at normal levels over the next 24 hours.
