Päikese aktiivsed piirkonnad ja pursked

There are six active regions visible on the disk. NOAA AR 3415 has evolved into a beta-delta magnetic field configuration, it is capable of producing M-class flares. The rest of the active regions have simple alpha or beta magnetic field configuration. Only C-class flaring has been observed in the last 24 hours, with the strongest one being a C5.0 one, from AR 3405 peaking at 15:49 UTC. C-class flares are expected and M-class flares are possible.

Krooniaine massiline väljavool

There were no Earth-directed Coronal Mass Ejections (CMEs) detected in the available coronagraph observations in the last 24 hours.

Päikesetuul

The solar wind arriving to the Earth is slow, with speeds around 400 km/s and interplanetary magnetic field around 8 nt. The CME from 22 August may arrive to the Earth today (although it has low chances of doing so), otherwise, similar slow wind conditions can be expected in the next 24 hours.

Geomagnetism

During the last 24 hours the geomagnetic conditions have been quiet (NOAA KP 1-2, K Bel 1-2). Mostly quiet to unsettled conditions can be expected for the next 24 hours, with possible active periods (in particular if the CME from 22 August arrives to the Earth, this has low chances of happening).

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 remained below the 1000 pfu threshold as measured by GOES 16. It is expected to remain so in the next 24 hours. The 24 hour electron fluence was at normal levels and is expected to remain so.
