Güneş Aktif Bölgeleri ve parlama

Solar flaring activity was low over the past 24 hours, with only C-class flares identified. The largest flare was a C4.4 flare (SIDC Flare 3284) peaking on January 16 at 07:26 UTC. There are currently 7 numbered active regions on the visible disk. SIDC Sunspot group 342 (NOAA AR 3959) and SIDC Sunspot Group 346 (NOAA Active Region 3961) are the most complex AR (beta-gamma-delta). The solar flaring activity is expected to be at moderate levels over the coming day with C-class flares expected and M-class flares probable and a chance of X-class flares.

Koronal Kütle Atılımı

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

Koronal delikler

The large east-west elongated negative polarity equatorial coronal hole (SIDC Coronal Hole 87) is still crossing the central meridian. A high-speed stream from this coronal hole may enhance the solar wind environment near Earth starting on Jan 16 and following days.

Güneş rüzgarı

Slow solar wind conditions are recorded over the past 24 hours. The solar wind at the Earth is slightly enhanced with speeds around 500 km/s and interplanetary magnetic field of 7nT with the Bz reaching a minimum value of -6 nT. Further enhancements of the solar wind speed are possible in the next 24h, due to the potential influence of the high-speed stream (HSS) associated with the coronal hole, which started to cross the central meridian on 11 Jan 2025.

Jeomanyetizma

Geomagnetic conditions were globally unsettled to active (Kp 4) and locally unsettled (K Bel 3). Quiet to active conditions are expected for the next 24 hours.

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 remained below the 1000 pfu alert threshold, and is expected to remain below the threshold during the next 24 hours. The 24h electron fluence was at normal levels and is expected to remain so.
