Slunečně aktivní oblasti a vzplanutí

Solar flaring activity was low over the past 24 hours. The largest flare was a C1.9 flare peaking on January 13 at 10:18 UTC, originated from a region from behind the east limb. A total of 3 numbered sunspot groups are currently on the disk, all having alpha or beta magnetic configuration. 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.

Vyhazování koronální hmoty

No new Earth-directed Coronal Mass Ejections (CMEs) have been detected in the available coronagraph images. The CME detected in LASCO C2 data on JAN 12 2026 05:48 UTC, directed to the north east, is back sided and is not expected to impact Earth.

Solární bouře

Fast solar wind conditions were recorded over the past 24 hours. The solar wind velocity varied between 520 to 590 km/s. The interplanetary magnetic field was around 8nT, with the Bz reaching a minimum value of -6 nT. Solar wind conditions are expected to remain elevated due to the continuation of the high-speed streams from negative polarity coronal holes (SIDC Coronal Hole 137 and SIDC Coronal Hole 142).

Geomagnetismus

Geomagnetic conditions reached active levels globally and locally (Kp 4, K bel 4) between Jan 12 21:00 UTC and Jan 13 03:00 UTC. Mostly unsettled to active geomagnetic conditions are expected over the next day due to the ongoing high speed stream.

Úrovně protonového toku

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

Elektronové toky na geostacionární oběžné dráze

The greater than 2 MeV electron flux was above the 1000 pfu threshold for the past 24 hours and is expected to remain so in the upcoming days. The 24h electron fluence was at moderate level and is expected to remain so in the next days.
