Bülletään

The X-ray flux remained below C-level. Active region NOAA 2806 is a simple bipolar region and has been stable. X-ray flux is expected to remain below C-level.

No Earth-directed Coronal Mass Ejections (CMEs) have been observed in coronagraph data.

The greater than 10 MeV proton flux was at nominal levels over the past 24 hours and is expected to remain so for the next 24 hours. The greater than 2 MeV electron flux peaked over the 1000 pfu event threshold during its diurnal maximum and is expected do so again today. The 24h electron fluence was at normal levels but rising and may reach moderate levels following the continuing enhanced Solar wind conditions.

Solar wind showed the continuation of moderately high speed stream conditions. Solar wind speed hovered around 500 km/s while total interplanetary magnetic field was at around 6nT with an unremarkable Bz component. The magnetic field was directed away from the Sun. Solar wind conditions are expected to slowly decay over the next days.

Geomagnetic conditions were mostly quiet to unsettled with a period of active conditions (both NOAA Kp and local K Dourbes reaching 4) around midnight. Geomagnetic conditions are expected to be quiet to unsettled as the high speed stream slowly decays over the next days.
