Solaraktive Regionen und Flares

There are three active regions visible on the disk (three rotated out of view in the last 24 hours). Only C-class flaring has been observed in the last 24 hours. The strongest flare was a C7.6 from NOAA AR 3485 close to the west limb (beta magnetic field configuration), peaking at 12:12 UTC on 15 November. More C-class flares can be expected in the next 24 hours.

Koronaler Massenauswurf

Two partial halo CMEs were observed erupting on 15 November (at 01:25 UTC and at 06:12 UTC), both eruptions were directed towards the north and most likely originated from the backside of the Sun as no related activity is seen on the frontside, so they are not expected to affect the Earth.

Sonnenwind

The Earth is immersed in slow solar wind, over the last 24 hours solar wind speed has remained constant around 400 km/s and interplanetary magnetic field around 5 nT. Same conditions are expected for the next 24 hours.

Geomagnetismus

During the last 24 hours the geomagnetic conditions were quiet to unsettled globally (NOAA KP 3) and reached active levels locally (K_Bel 4). Mostly quiet to unsettled conditions are expected for the next 24 hours.

Protonenflusswerte

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.

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): 036, basierend auf 10 Stationen.
