Aktywne obszary słoneczne i rozbłyski

Solar flaring activity over the past 24 hours reached moderate levels. The largest flare was a M1.9-flare, with peak time 12:46 UTC on October 02, associated with NOAA AR 3455 (beta magnetically complexity). There are currently 9 numbered active regions on the visible disc, NOAA AR 3450 (beta-gamma) remains stable and is the most magnetically complex regions on the disc, all other regions have simple alpha or beta magnetic field configurations. The solar flaring activity is likely to be at quiet to moderate levels over the coming days with C-class flares expected, M-class flares possible and a low chance for isolated X-class flaring.

Koronalny wyrzut masy

No Earth-directed Coronal Mass Ejections have been detected in the last 24 hours available SOHO/LASCO images.

Dziury koronalne

Two small positive polarity coronal holes close to the equator have crossed the central meridian yesterday on October 02, and on October 01.

Wiatr słoneczny

In the last 24 hours, the solar wind condition near Earth was stable with the solar wind parameters showing a slow wind speed regime. The total interplanetary magnetic field was below 7.5 nT. The Bz-component of the interplanetary magnetic fluctuated between positive and negative values with a minimum value of -6.9 nT. The solar wind speed had values varying between 325 km/s and 480 km/s. The phi-angle was in the positive sector (directed away from the Sun). Slow solar wind conditions are expected in the next 12-24 hours then later some enhancement due to the wind speed associate to the small coronal holes (2 small positive polarity coronal holes that crossed the central meridian on October 01 and 02) may be observed in the solar wind parameters recorded near Earth.

Geomagnetyzm

The geomagnetic conditions over the past 24 hours were globally quiet with one period of unsettled condition (Kp-NOAA, K-Bel 3). Quiet to unsettled conditions is expected in the next 24 hours.

Poziomy przepływu protonów

The greater than 10 MeV proton flux was at background levels over the last 24 hours. It expected to mostly remain at background level, however possible rise of the proton flux cannot be fully excluded due to the current number of complex region and the flaring activity on the disc.

Strumienie elektronów na orbicie geostacjonarnej

The greater than 2 MeV electron flux measured by GOES-16 was below the 1000 pfu threshold. The greater than 2 MeV electron flux is expected remains below the threshold in the next 24 hours. The 24h electron fluence was at normal levels and is expected to remain at normal levels in the next 24 hours.
