Aktywne obszary słoneczne i rozbłyski

Solar flaring activity was high over the past 24 hours. The largest flare was a M5.1-flare, with peak time 22:08 UTC on August 21 2024, from NOAA AR 3796 (beta-gamma). There are currently 11 numbered active regions on the visible disk. NOAA AR 3784 has now rotated over the west limb. NOAA AR 3796 and 3790 are the most complex AR (beta- gamma). 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.

Koronalny wyrzut masy

There was an eruption seen in AIA/SDO 193 on August 21 at 18:00 UTC on the center of the disk, but no associated Coronal Mass Ejection (CME) has yet been observed in the available coronagraph images. No other earth-directed CMEs have been observed.

Wiatr słoneczny

The solar wind at the Earth remained slow over the last 24 hours. The solar wind speed was around 350 km/s and the interplanetary magnetic field was stable around 7nT. The Bz reached a minimum value of -7nT. Small enhancements of the solar wind speed may occur on August 22 and 23 due to a possible high-speed-stream arrival associated with the coronal holes that crossed the central meridian on August 19 and August 20 respectively.

Geomagnetyzm

Geomagnetic conditions were both globally and locally mainly quiet to unsettled (Kp 3+ and K Bel 3), which a short active period locally (K Bel 4). Geomagnetic conditions may reach active levels on the 22 and 23 August, due to possible high-speed stream arrivals.

Poziomy przepływu protonów

The greater than 10 MeV proton flux remained below the 10 pfu threshold and is expected to remain so over the next 24 hours.

Strumienie elektronów na orbicie geostacjonarnej

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.
