Solaraktive Regionen und Flares

Solar flaring activity was high over the past 24 hours, with several M-class flares. The largest flare was a M5.1-flare, with peak time 20:12 UTC on August 23 2024, from NOAA AR 3800 (beta-gamma). There are currently 9 numbered active regions on the visible disk. The most complex active regions are beta-gamma (NOAA AR 3796, 3790, 3799, 3800 and 3801). The solar flaring activity is expected to be at moderate levels over the next 24 hours with C-class flares expected, M-class flares probable and a small chance of X-class flares.

Koronaler Massenauswurf

The Coronal Mass Ejections (CMEs) detected in LASCO C2 data at 02:06 UTC on August 23 has been further analyzed. Although the bulk of the CME is directed to the west, an Earth-directed component may arrive at Earth on August 27. No other Earth-directed CMEs have been detected in the available coronagraph images.

Sonnenwind

The solar wind at the Earth remained slow over the last 24 hours. The solar wind speed was around 370 km/s and the interplanetary magnetic field was stable around 7nT. The Bz reached a minimum value of -8nT. Slow solar wind conditions are expected in the next 24h.

Geomagnetismus

Geomagnetic conditions were globally and locally quiet to unsettled (Kp 3+ and K Bel 3). Quiet conditions are expected in the next 24 hours.

Protonenflusswerte

The greater than 10 MeV proton flux remained below the 10 pfu threshold and is expected to remain so over the next days.

Elektronenflüsse im geostationären Orbit

The greater than 2 MeV electron flux remained below the 1000 pfu alert threshold, and is expected to remain below the threshold during the next 24 hours. The 24h electron fluence was at normal levels and is expected to remain so.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 236, basierend auf 14 Stationen.
