Güneş Aktif Bölgeleri ve parlama

A total of 14 numbered sunspot groups were identified on the disk over the past 24 hours. Only C-class flaring was observed. The largest flare was a C5.0 flare (SIDC Flare 5302) peaking on August 29 at 17:10 UTC, which was produced by SIDC Sunspot Group 614 (NOAA Active Region 4197). This is the most complex sunspot group currently visible, with beta-gamma-delta magnetic field configuration, located at S17E04. Solar flaring activity is expected to be moderate over the next 24 hours, with C-class flares expected and M-class flares likely.

Koronal Kütle Atılımı

No Earth-directed Coronal Mass Ejections (CMEs) have been observed in the last 24 hours. A slow partial halo CME was seen erupting towards the southwest in LASCO C2 data at 16:48 UTC on 29 August. This CME is backsided and will not arrive to the Earth.

Koronal delikler

A narrow equatorial negative polarity coronal hole (SIDC Coronal Hole 122) crossed central meridian on 28 August, its associated high speed stream may be expected at the Earth late on 31 August.

Güneş rüzgarı

The Earth is inside slow solar wind with speeds around 380 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, with a high speed stream expected to arrive after that.

Jeomanyetizma

Geomagnetic conditions have been quiet to unsettled (Kp between 0 and 2 and K_Bel 0 and 3). Similar conditions are expected for the next 24 hours.

Proton akı seviyeleri

The greater than 10 MeV proton flux has been below the 10 pfu threshold in the last 24 hours. 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.
