Solaraktive Regionen und Flares

There are three active regions visible on the disk. NOAA AR 3486 is rotating out of view over the west limb. Most of the activity comes from the ARs rotating into view over the east limb. In particular, NOAA 3490, with beta magnetic field configuration, but the full extent of the AR is not yet visible. This AR produced two M-class flares in the last 24 hours, the strongest one was an M1.1 flare peaking at 16:44 UTC on 18 November. More M-class flares can be expected in the next 24 hours.

Koronaler Massenauswurf

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

Koronale Löcher

The high speed solar wind emanating from the low latitudinal extension of a high latitude coronal hole (in the northern hemisphere, negative polarity) may arrive to the Earth in 24 hours. Although, due to the high latitude location of the coronal hole, the high speed solar wind may miss the Earth. The solar wind from a second, equatorial, coronal hole with positive polarity may affect the Earth in 48 hours.

Sonnenwind

The Earth is immersed in slow solar wind with speed around 380 km/s and interplanetary magnetic field around 5 nT. Same conditions are expected for the next 24 hours. The situation will change when the high speed solar wind from two coronal holes arrives to the Earth in 24 to 48 hours.

Geomagnetismus

During the last 24 hours the geomagnetic conditions were quiet globally and locally (NOAA KP 2, K_Bel 2). Mostly quiet conditions are expected for the next 24 hours, active conditions can be expected after due to the arrival of a high speed stream.

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): 065, basierend auf 10 Stationen.
