Solaraktive Regionen und Flares

There are two active regions visible on the disk. The strongest flare was an M1.2 from an unnumbered region on the east limb, peaking at 05:42 UTC. More M-class flares are possible in the next 24 hours.

Koronaler Massenauswurf

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

Koronale Löcher

Two coronal holes crossed the central meridian in the past 24 hours, one with negative polarity at high northern latitudes and an equatorial one with positive polarity.

Sonnenwind

The Earth is immersed in slow solar wind, over the last 24 hours solar wind speed has decreased to 300 km/s and the interplanetary magnetic field is around 5 nT. Same conditions are expected for the next 24 hours.

Geomagnetismus

During the last 24 hours the geomagnetic conditions were quiet globally and locally (NOAA KP 1, K_Bel 1). Mostly quiet conditions are expected for the next 24 hours.

Protonenflusswerte

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

Elektronenflüsse im geostationären Orbit

The greater than 2 MeV electron flux was 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, it is expected to stay at those levels for the next 24 hours.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 033, basierend auf 07 Stationen.
