Solaraktive Regionen und Flares

A total of 4 numbered sunspot groups were identified on the disk over the past 24 hours. Flaring activity has been very low in the last 24 hours, no C-class flares or higher detected. The sunspot groups visible on disk have relatively simple magnetic field configuration (alpha or beta). Solar flaring activity is expected to be low over the next 24 hours.

Koronaler Massenauswurf

No Earth-directed CMEs were observed in the last 24 hours. A wide CME (angular width about 90 degrees) was seen erupting towards the SW at 18:00 UTC on 13 April, this CME is backsided and will not arrive to the Earth.

Sonnenwind

The solar wind speed is low, around 380 km/s with interplanetary magnetic field magnitude of 5 nT, with positive polarity (away from the Sun). Similar conditions are expected for the next 24 hours.

Geomagnetismus

Geomagnetic conditions have been quiet (Kp and K_BEL up to 2). Similar conditions can be expected for the next 24 hours.

Protonenflusswerte

The greater than 10 MeV proton flux, as measured by GOES-18, was below the 10 pfu threshold level over the past 24 hours and is expected to remain so for the next 24 hours.

Elektronenflüsse im geostationären Orbit

The greater than 2 MeV electron flux, as measured by GOES-18 and GOES-19 have remained close to the 1000 pfu alert threshold over the past 24 hours. The flux is expected to remain mostly below the alert threshold over the next 24 hours. The 24-hour electron fluence was at normal to moderate levels over the past 24 hours and is expected to remain at these levels over the next 24 hours.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 059, basierend auf 18 Stationen.
