Aktywne obszary słoneczne i rozbłyski

Solar flaring activity was moderate over the past 24 hours, with 1 M-class flare identified. A total of 9 numbered sunspot groups were identified on the disk over the past 24 hours. SIDC Sunspot Group 607 (NOAA 4191) has a Beta-Gamma magnetic configuration and was the most active on disk sunspot group over the past 24 hours. The largest flare was a M1.9 flare (SIDC Flare 5195) peaking on August 23 at 20:06 UTC from on the east-limb, most likely from SIDC Sunspot Group 614. Solar flaring activity is expected to be low over the next 24 hours, with C-class flares very likely and a chance for M-class flares.

Koronalny wyrzut masy

No Earth-directed Coronal Mass Ejections (CMEs) have been detected in the available coronagraph images.

Dziury koronalne

The SIDC Coronal Hole 126 (mid-latitude coronal hole with a negative polarity) has finished it's crossing of the central meridian. A high-speed stream from this coronal hole may enhance the solar wind environment near Earth on August 26.

Wiatr słoneczny

Slow solar wind conditions were recorded over the past 24 hours. The solar wind speed has further decreased from 460km/s to 400km/s over the past 24 hours. The interplanetary magnetic field is around 4 nT, with the Bz reaching a minimum value of -3 nT. In the next 24 hours, we expect slow solar wind conditions.

Geomagnetyzm

Geomagnetic conditions were globally and locally quiet (Kp and K Bel 2). Quiet to unsettled conditions are expected in the next 24 hours.

Poziomy przepływu protonów

The greater than 10 MeV proton flux showed a slight increase but remained well below the 10 pfu threshold and is expected to remain below the 10 pfu threshold over the next days.

Strumienie elektronów na orbicie geostacjonarnej

The greater than 2 MeV electron flux as measured by GOES 18 remained below the 1000 pfu alert threshold (GOES 19 measurements indicated a short and minimal crossing of the 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.
