Güneş Aktif Bölgeleri ve parlama

Solar flaring activity was low over the past 24 hours, with several C-class flares recorded. The largest flare was a C2.5 flare (SIDC Flare 6189), peaking on November 24 at 06:18 UTC, associated with SIDC Sunspot Group 705 (NOAA Active Region 4290; magnetic type beta). There are currently seven numbered active regions on the visible solar disk. SIDC Sunspot Group 705 was the main driver of the flaring activity observed over the past 24 hours. A new region rotated on the disk from behind the east limb and was numbered SIDC Sunspot Group 708 (NOAA Active Region 4293; magnetic type beta), but it remained quiet. The remaining active regions did not produce any significant flaring activity. Solar flaring activity is expected to be low over the next 24 hours, with C-class flares very likely and a chance for M-class flares.

Koronal Kütle Atılımı

No Earth-directed coronal mass ejections (CMEs) have been identified in the available coronagraph imagery over the past 24 hours.

Güneş rüzgarı

Over the past 24 hours, the solar wind parameters (ACE and DSCOVR) became slightly disturbed, possibly due to arrival of a high-speed stream from a positive polarity coronal hole (SIDC Coronal Hole 128). The interplanetary magnetic field reaching values up to 15 nT. The solar wind speed increased from 430 to 710 km/s. The southward component of the interplanetary magnetic field fluctuated between -15 nT and 11 nT. Solar wind conditions are expected to remain slightly elevated over the next days under the influence of a high-speed stream (HSS).

Jeomanyetizma

Geomagnetic conditions reached active levels globally (NOAA Kp 4-), between 15:00 and 18:00 UTC on November 23. Locally over Belgium quiet to unsettled conditions were observed (K-Bel: 1 to 3). Mostly unsettled to active geomagnetic conditions are expected over the next 24 hours, with a chance of isolated minor or moderate storm periods due to the ongoing high-speed stream influence.

Proton akı seviyeleri

Over the past 24 hours the greater than 10 MeV GOES proton flux has been at nominal levels and is expected to remain at nominal levels over the next days.

Jeostatik yörüngedeki elektron akıları

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