Güneş Aktif Bölgeleri ve parlama

Solar flaring activity was low over the past 24 hours with several C-class flares. The largest flare was a C6.3-flare, with peak time 08:56 UTC on Jan 15 2025, from SIDC Sunspot Group 346 NOAA AR 3961 (beta). There are currently 5 numbered active regions on the visible disk. SIDC Sunspot group 342 (NOAA AR 3959) is the most complex AR (beta-gamma). The solar flaring activity is expected to be at low levels over the coming day with C-class flares expected and M-class flares probable.

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.

Güneş rüzgarı

Slow solar wind conditions were recorded over the past 24 hours. The solar wind has gradually increased speeds around 520 km/s and is currently again around 420 km/s. The interplanetary magnetic field is stable to 8 nT with the Bz reaching a minimum value of -7 nT. Enhancements of the solar wind speed are expected in the next 24h, due to the potential arrival of the high-speed stream (HSS) associated with the coronal hole, which started to cross the central meridian on 13 Jan 2025.

Jeomanyetizma

Geomagnetic conditions were globally unsettled to active (Kp 4) and locally unsettled (K Bel 3). Quiet to active conditions with possible isolated minor geomagnetic storm levels 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, even if a slight increase may be observed, it 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.
