Päikese aktiivsed piirkonnad ja pursked

There are twelve active regions visible on the disk. There were two M-class flares in the last 24 hours, the strongest one was an M4.4 from NOAA AR 3435 (beta magnetic field configuration), peaking at 03:28 UTC. The other M-class flare was produced by the new NOAA ARs 3435 (beta magnetic field configuration). NOAA AR 3441 has a beta-gamma magnetic field configuration and NOAA AR 3443 beta- delta, all the other regions have simpler alpha or beta magnetic field configuration. More M-class flares can be expected in the next 24 hours, X-class flares are possible.

Krooniaine massiline väljavool

No Earth directed CMEs were observed in the last 24 hours.

Päikesetuul

In the last 24 hours, the solar wind speed at the Earth has been around 320 km/s and the interplanetary magnetic field around 5 nT. The CMEs from 20 and 21 September can arrive to the Earth in the next 24 hours, and change the solar wind conditions.

Geomagnetism

During the last 24 hours the geomagnetic conditions have been quiet to unsettled, both globally and locally (NOAA KP 3, K_Bel 3). Geomagnetic conditions are expected to reach minor to moderate storm levels if the expected CMEs from 21 and 22 September arrive to the Earth.

Prootoni voo tasemed

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

Elektronivoog geostatsionaarsel orbiidil

The greater than 2 MeV electron flux was above the 1000 pfu, as measured by GOES 16. It has gone down in the last hours, but it may increase over the threshold again in the next 24 hours. The 24 hour electron fluence was at moderate levels, it is expected to stay at those levels for the next 24 hours.
