Aktywne obszary słoneczne i rozbłyski

Solar flaring activity over the past 24 hours was moderate. There are seven numbered regions on the visible solar disc with NOAA ARs 3828 (beta-gamma), 3831 (beta) and 3835 (beta) being the most active in the last 24 hours. NOAA AR 3835 produced the strongest flare of the day, an M3.7 flare with peak at 21:39 UTC on 22 September. The solar flaring activity is likely to remain at moderate over the coming days, with more M-class flares possible.

Koronalny wyrzut masy

A partial halo CME with apparent angular width around 180 degrees erupted on 22 September at 21:37 UTC (first seen by LASCO C2), with a speed of around 1300 km/s. It is directed to the southeast but it has an Earth component that could hit the Earth around 6:00 UTC on 25 September, according to EUHFORIA.

Dziury koronalne

A small equatorial positive polarity coronal hole crossed the central meridian on 21 September. A mild high speed stream may arrive at Earth on 25 September.

Wiatr słoneczny

Over the past 24 hours the solar wind parameters (ACE and DSCOVR) were indicative of a slow solar wind regime. The interplanetary magnetic field was below 9 nT with a minimum Bz of -6 nT. The solar wind velocity decreased to about 380 km/s. Similar slow wind conditions are expected to continue for the next 24 hours.

Geomagnetyzm

The geomagnetic conditions over the past 24 hours were quiet both globally and locally (Kp and K_Bel from 0 to 2). Similar conditions are expected for the next 24 hours.

Poziomy przepływu protonów

Over the past 24 hours the greater than 10 MeV GOES proton flux has been at nominal levels and is expected to remain so over the next 24 hours.

Strumienie elektronów na orbicie geostacjonarnej

The greater than 2 MeV electron flux as measured by GOES 16 and GOES 18 has been slightly above the 1000 pfu threshold on 22 September. It is expected to be below threshold over the next 24 hours. The 24h electron fluence was at normal levels and is expected to remain so over the next 24 hours.
