Aktywne obszary słoneczne i rozbłyski

During last 24 hours several low C-class flares were reported and majority of them were partially occulted flares originating from the NOAA AR 3413 which now fully rotated behind the West solar limb. The photospheric magnetic field of NOAA AR 3421(presently situated at the center of the solar disc) has increased in complexity which resulted in several C-class flares during recent hours. Two recurrent active regions (previously NOAA AR 3403 and 3409) are rotating across the East solar limb on the visible side of the solar disc. We expect that these two regions will be also source of flaring activity in the coming hours. The solar flaring activity is expected to remain on the similar level with the C-class flares probable while isolated M-class flares are possible but not very probable.

Koronalny wyrzut masy

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

Dziury koronalne

Rather narrow and strongly elongated in the longitude, negative polarity coronal hole which is situated in the Northern solar hemisphere started to cross the central meridian today. The solar wind originating from this coronal hole can be expected at Earth in the morning of September 07.

Wiatr słoneczny

Earth is presently inside the slow solar wind with velocity of about 410 km/s and the interplanetary magnetic field magnitude is around 4 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 was fluctuating around the 1000 pfu threshold. The 24h electron fluence is at moderate level. We do not expect significant change in these two parameters in the coming 24 hours.
