Päikese aktiivsed piirkonnad ja pursked

There are seven visible ARs on the solar disk. Solar activity has been low, only C-class flaring in the last 24 hours. The region that was creating most of the activity, NOAA AR 3679, has now rotated out of view. The strongest flare was a C5.3 one peaking at 09:36 UTC, from NOAA AR 3691. This is the AR that caused several X-flares in the last rotation. Still showing a beta-gamma-delta magnetic field configuration, this AR has potential for strong flares, but seems so far calmer than in the previous rotation. More C-class flares can be expected and M-class flares are possible.

Krooniaine massiline väljavool

No Earth directed CME has been observed in the last 24 hours.

Päikesetuul

The solar wind at the Earth is slow, with speeds around 360 km/s and interplanetary magnetic field around 6 nT. Similar conditions can be expected for the next 24 hours. There are low chances of a glancing blow of the CME from 23 May after that.

Geomagnetism

Geomagnetic conditions have been mostly quiet both at planetary and local levels (Kp and K_Bel up to 3).Similar conditions can be expected in the next 24 hours. A glancing blow from the 23 May CME (with low chances of arrival) may create active conditions.

Prootoni voo tasemed

The 10 MeV GOES-18 proton flux was below threshold in the past 24 hours and is expected to remain so in the next 24 hours.

Elektronivoog geostatsionaarsel orbiidil

The greater than 2 MeV electron flux from GOES 16 was below the threshold level in the last 24 hours. It is expected to remain below the threshold during the next 24 hours. The electron fluence was at normal levels for the last 24 hours and is expected to remain so.
