Güneş Aktif Bölgeleri ve parlama

Solar flaring activity was low over the past 24 hours, with only C-class flares identified. A total of 5 numbered sunspot groups were identified on the disk over the past 24 hours. SIDC Sunspot Group 693 (NOAA Active Region 4284) currently located at S07W10 has a Beta-Gamma magnetic configuration and was the most complex and active region over the past 24 hours. The largest flare was a C7.5 flare (SIDC Flare 6112) peaking on November 17 at 01:30 UTC, which was produced by SIDC Sunspot Group 693 (NOAA Active Regions 4280, 4284). 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 136 (small mid-latitude coronal hole with a negative polarity) just started crossing the central meridian. The influence of the associated high speed stream is expected to impact earth during Nov 20 2025.

Güneş rüzgarı

The solar wind conditions at Earth are gradually returning to slower solar wind conditions over the past 24h. The solar wind speed decreased from 628 to 546 km/s and interplanetary magnetic field around 7 nT with the Bz reaching a minimum value of -3 nT. Over the next 24 hours the solar wind conditions may be enhanced following the potential arrival of the high speed stream (HSS) from coronal hole 126.

Jeomanyetizma

Geomagnetic activity was active globally and unsettled locally over the past 24 hours. Geomagnetic conditions are expected to be unsettled to active in the next 24h due to a potential high-speed stream arrival.

Proton akı seviyeleri

The greater than 10 MeV proton flux was 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.
