Aktywne obszary słoneczne i rozbłyski

During last 24 hours number of C-class flares and one M-class flare were reported. The M 2.0 flare which peaked at 08:12 UT this morning was originating from the Catania sunspot group 41 (NOAA AR 3421) which was, together with the Catania sunspot group 39 (NOAA AR 3419), source of the majority of the flaring activity in the last 24 hours. The presently available observations do not show clear on disc signatures of the possibly associated CME (coronal dimming and EIT waves), or the CME in the white light observations. However, since the source region of the flare, the Catania sunspot group 41 (NOAA AR 3421) was at center of the solar disc during the flaring, any wide CME originating from this region would be Earth directed. More will be reported when the data become available. The solar flaring activity is expected to remain on the similar level in the coming hours, with the C-class flares expected and with the isolated M-class flares possible.

Koronalny wyrzut masy

During last 24 hours there were no Earth directed CMEs detected in the available coronagraph data.

Wiatr słoneczny

Earth is still inside the slow solar wind with velocity of about 390 km/s and the interplanetary magnetic field magnitude is around 6 nT.

Geomagnetyzm

During last 24 hours the geomagnetic conditions were quiet to unsettled and we expect such a geomagnetic conditions to persist in the coming hours.

Poziomy przepływu protonów

The greater than 10 MeV proton flux was at the background levels and we do not expect significant change in the coming hours.

Strumienie elektronów na orbicie geostacjonarnej

The greater than 2 MeV electron flux has continue to fluctuate around the 1000 pfu threshold, and it is expected to stay so in the coming hours. The 24h electron fluence is at moderate to normal level and we expect it will be at normal level in the coming hours.
