Aktywne obszary słoneczne i rozbłyski

Solar flaring activity has been quite over the past 24 hours with few C-class flares. The larger flare was a C8.9-class flare produced by NOAA AR 3395 (Catania sunspot group 14) and was peaking at 09:15 UTC on August 12. The other regions did not show any significant flaring activity. Solar flaring activity is expected to remain quite 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 solar wind parameters were mostly close to nominal levels over the past 24 hours. The solar wind speed was ranging from 480 km/s to 490 km/s). The total interplanetary magnetic field was below 7.8 nT. The north-south component was fluctuating between -5.4 nT and 7.0 nT. The solar wind conditions are expected to remain as such for the next 24 hours.

Geomagnetyzm

Geomagnetic conditions were mostly quiet with some short unsettled periods (NOAA Kp 1-3, K Belgium 1-2) over the past 24 hours. Quiet conditions with possible short unsettled periods are expected for the next 24 hours.

Poziomy przepływu protonów

The greater than 10 MeV proton flux has now decreased and returned to nominal values. New proton event cannot be excluded due to the flaring activity, however, it is not very likely.

Strumienie elektronów na orbicie geostacjonarnej

The greater than 2 MeV electron flux was above the level of the 1000 pfu alert threshold for a short period, and is expected to remain below threshold during the next 24 hours. The 24h electron fluence was at normal levels and is expected to remain so.
