Aktywne obszary słoneczne i rozbłyski

Solar flaring activity was low over the past 24 hours, with only C-class flares identified. The largest flare was a C2.2 flare peaking on Feb 22 at 06:33 UTC, which was produced by SIDC Sunspot Group 762 (NOAA Active Regions 4342, 4374). A total of 1 numbered sunspot groups were identified on the disk over the past 24 hours, and currently no sunspot on the disk. Solar flaring activity is expected to be low over the next 24 hours, with C-class flares very 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 enhanced during the past 24 hours. The solar wind speed ranged between 441 km/s and 734 km/s. The interplanetary magnetic field ranged between 2 nT and 15 nT. The North- South component (Bz) ranged between -10 and 14 nT. This is possibly due to the early arrival of the high speed streams (HSSs) associated with the extension of the negative polarity, equatorial, recurrent coronal hole (SIDC Coronal Hole 147) which started to cross the central meridian since Feb 20. In the next 24 hours, enhanced solar wind conditions are possible with the further arrival of HSSs from the same coronal hole.

Geomagnetyzm

Geomagnetic conditions were globally at quiet to minor storm conditions (NOAA Kp 1 to 5). It was locally over Belgium at quiet to active conditions (K BEL 2 to 4). This is possibly due to the early arrival of the high speed streams (HSSs) associated with the extension of the negative polarity, equatorial, recurrent coronal hole (SIDC Coronal Hole 147) which started to cross the central meridian since Feb 20. Active to moderate storm conditions (k 4 to 6) are possible in the next 24 hours with the further arrival of HSSs from the same coronal hole.

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 20:00 UTC to 23:30 UTC on Feb 21 over the past 24 hours. It may exceed the threshold level again in the next 24 hours. The greater than 2 MeV electron flux, as measured by GOES-19 satellite, was below the 1000 pfu threshold level in the last 24 hours, and is expected to remain so. The 24h electron fluence was at normal levels and is expected to remain so in the coming 24 hours.
