Aktywne obszary słoneczne i rozbłyski

Solar flaring activity was very low over the past 24 hours. The X-ray flux was below C level. A total of 3 numbered sunspot groups were identified on the disk over the past 24 hours. All active regions were simple with alpha magnetic configurations. Solar flaring activity is expected to be low over the next 24 hours, with C-class flares likely.

Koronalny wyrzut masy

No Earth-directed coronal mass ejections (CMEs) were detected in the available coronagraph observations during last 24 hour.

Wiatr słoneczny

Solar wind parameters were slightly enhanced during the past 24 hours. The solar wind speed ranged between 418 km/s and 570 km/s. The interplanetary magnetic field ranged between 3 nT and 16 nT. The North- South component (Bz) ranged between -8 and 12 nT. This was possibly due to sector boundary crossing or with the late arrival of interplanetary coronal mass ejection associated to the CME (associated to a filament eruption) that was observed lifting from the Sun in the afternoon of Feb 16, but it is not clear. Slow solar wind conditions are expected in the next 24 hours.

Geomagnetyzm

Geomagnetic conditions were globally at quiet to active conditions (NOAA Kp 2 to 4). It was locally over Belgium at quiet to minor storm conditions (K BEL 1 to 5). Global geomagnetic condition was at active conditions from 21:00 on Feb 20 to 03:00 UTC on Feb 21, and locally over Belgium at minor storm conditions from 23:00 UTC on Feb 20 to 00:00 UTC on Feb 21 due to enhanced solar wind conditions. Quiet to active conditions are expected in the next 24 hours.

Poziomy przepływu protonów

The greater than 10 MeV GOES proton flux was below the threshold level over the past 24 hours and it is expected to remain so for the next 24 hours.

Strumienie elektronów na orbicie geostacjonarnej

The greater than 2 MeV electron flux, as measured by GOES-18 satellite, increased and exceeded the 1000 pfu threshold level from 11:45 UTC on Feb 20 to 01:15 UTC on Feb 21 over the past 24 hours. The greater than 2 MeV electron flux, as measured by GOES-19 satellite, exceeded above the 1000 pfu threshold level around 07:00 UTC on Feb 20 and dropped below the threshold level around 21:10 UTC on Feb 20. The electron flux may exceed the threshold level again in the next 24 hours. The 24h electron fluence was at moderate levels and is expected to remain at moderate level in the coming 24 hours.
