Güneş Aktif Bölgeleri ve parlama

Solar flaring activity was low over the past 24 hours, with only C-class flares identified. The largest flare was a C9.2 flare (SIDC Flare 5247) peaking on August 27 at 12:50 UTC, which was produced by SIDC Sunspot Group 617 (NOAA Active Region 4199). A total of 14 numbered sunspot groups were identified on the disk over the past 24 hours. Solar flaring activity is expected to be low to moderate over the next 24 hours, with C-class flares expected and a chance for M-class flares.

Koronal Kütle Atılımı

No Earth-directed Coronal Mass Ejections (CMEs) have been observed in the last 24 hours.

Güneş rüzgarı

The Earth is inside slow solar wind with speeds around 400 km/s and interplanetary magnetic fields of about 7 nT (directed towards the Sun, negative polarity). Similar conditions can be expected for the coming 24 hours.

Jeomanyetizma

Geomagnetic conditions have been quiet to unsettled (Kp and B_Bel between 0 and 3). Similar conditions are expected for the next 24 hours.

Proton akı seviyeleri

The greater than 10 MeV proton flux returned to nominal levels (below the 10 pfu threshold) at 15:30 UT on 27 August. It is expected to remain at nominal levels.

Jeostatik yörüngedeki elektron akıları

The greater than 2 MeV electron flux as measured by GOES 18 and 19 remained below the 1000 pfu alert threshold, similar conditions expected for the next 24 hours. The 24 h electron fluence was at normal levels and is expected to remain so.
