Aktywne obszary słoneczne i rozbłyski

Solar flaring activity has been quite to moderate over the past 24 hours with several C-class flares. The most complex and productive region NOAA Active Region (AR) 3386 (Catania sunspot group 01) has now rotated over the East limb. The other most active region, NOAA AR 3387 (Catania sunspot group 07), continued to produce many C-class flares and is now also rotating over the East limb. The larger flare was a C8.8 produced by NOAA AR 3394 (Catania sunspot group 13) and was peaking at 18:10 UTC on August 08. The other regions do not show significant flaring activity. Solar flaring activity is expected to be quite to moderate over the next 24 hours with a high probability of C-class flare and a small chance of M-class flares.

Koronalny wyrzut masy

No coronal mass ejection (CME) with an Earth- directed component was identified in the SOHO/LASCO-C2 coronagraph images over the past 24 hours.

Wiatr słoneczny

The general solar wind conditions were close to the background levels over the past 24 hours: The solar wind speed slowly decreased from 515 km/s in the beginning of the period to current values below 400 km/s. The total interplanetary magnetic field was below 7.5 nT . The north-south component was fluctuating between -4.7 nT and 7.8 nT. The coronal mass ejection from August 05 at 07:12 UTC heading towards Earth may still disturb the solar wind conditions later today. The second coronal mass ejection from August 05 at 22:25 UTC is not expected to disturb the solar wind conditions.

Geomagnetyzm

Geomagnetic conditions were mostly quiet with some short unsettled periods recorded locally in Belgium(NOAA Kp 1-2, K Belgium 1-3) over the past 24 hours. Quiet to unsettle conditions is expected for the next 24 hours.

Poziomy przepływu protonów

The greater than 10 MeV proton flux started to rise at 21:46 UTC on August 07 and crossed the 10 MeV warning threshold at 01:10 UTC on August 08 as measured by GOES. This proton event was following the X1.5 class flare that was observed on August 07 peaking at 20:46 UTC. The greater than 10 MeV proton flux is expected to remain above the 10 MeV warning threshold in the next 12-24 hours before decreasing. New event cannot be excluded due to the flaring activity.

Strumienie elektronów na orbicie geostacjonarnej

The greater than 2 MeV electron flux was at the level of the 1000 pfu alert threshold, and is expected to remain close to this level or just below the threshold during the next 24 hours. The 24h electron fluence was at nominal levels and is expected to remain so.
