Aktywne obszary słoneczne i rozbłyski

A total of 8 numbered sunspot groups were identified on the disk over the past 24 hours. Solar flaring activity was low over the past 24 hours, with only C-class flares identified. The largest flare was a C4.9 flare (SIDC Flare 3663) peaking on February 20 at 15:01 UTC, which was produced by SIDC Sunspot Group 405 (NOAA Active Region 3996). Solar flaring activity is expected to be moderate over the next 24 hours, with C-class flares expected and M-class flares likely.

Koronalny wyrzut masy

A wide CME erupting towards the west was seen on 20 February at 00:24 UTC (first seen by LASCO C2), related to a C8.1 flare and a type-II radio burst. The CME speed is estimated to be around 400 km/s, a glancing blow from this CME may be observed at Earth on 24 February. A filament erupted then in the SE quadrant, leading to a CME seen at 10:00 UT on 20 February, that is not expected to arrive to the Earth.

Wiatr słoneczny

The solar wind speed at Earth has decreased to 350 km/s in the last 24 hours, with an interplanetary magnetic field currently around 5 nT. Similar slow solar wind conditions can be expected for the next 24 hours.

Geomagnetyzm

Geomagnetic conditions have been quiet to unsettled globally and locally (Kp and K_Bel up to 3). Similar conditions can be expected for the next 24 hours.

Poziomy przepływu protonów

The greater than 10 MeV proton flux was below the threshold level over the past 24 hours. It is expected to remain below the threshold level over the next 24 hours.

Strumienie elektronów na orbicie geostacjonarnej

The greater than 10 MeV GOES 16 and 18 electron flux has been below the threshold in the last 24 hours It is expected to remain below the threshold in the next 24 hours. The 24-hour electron fluence is currently at normal levels and is expected to remain so in the next 24 hours.
