Aktywne obszary słoneczne i rozbłyski

During last 24 hours solar flaring activity has decreased and only a few C-class flares were reported. The strongest reported flare was GOES C8.3 flare which peaked at 01:55 UT on September 10. The flare originated from the Catania sunspot group 44 (NOAA AR 3423) which somewhat decreased in the complexity of its photospheric magnetic field and it has presently beta configuration. The EUV observations show that the flare was associated with the eruption, but as the coronagraph data are not yet available it is not possible to estimate if the associated CME will be Earth directed. More will be reported when data become available. All the numbered active regions have presently beta configuration of their photospheric magnetic field. We can expect C-class flares in the coming hours while isolated M-class flares are possible but not very probable.

Koronalny wyrzut masy

Presently available observations do not show any Earth directed CME.

Dziury koronalne

Two narrow and elongated coronal holes started to cross the central meridian today, one at the Northern and another one at Southern solar hemisphere. The coronal hole at the Northern hemisphere has positive polarity and the one at Southern hemisphere is somewhat smaller and it has negative polarity. The solar wind associated with these coronal holes can be expected at Earth starting from the afternoon of September 13.

Wiatr słoneczny

Earth is still inside the slow solar wind with the solar wind plasma characteristics fluctuating very little during the last 24 hours. The solar wind velocity remained to be about 330 km/s and the interplanetary magnetic field magnitude is about 6 nT.

Geomagnetyzm

During last 24 hours the geomagnetic conditions were quiet and we expect them to stay so 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 still fluctuates around the 1000 pfu threshold. The 24h electron fluence is at normal level. We do not expect significant change in the coming hours.
