Bülletään

Solar X-ray flux has been below background (B) level throughout the period. There are no spotted regions on disc and X-ray flux is expected to remain at or below background (B) values.

There were no Earth directed coronal mass ejections observed in coronagraph data.

The greater than 10 MeV proton flux was at background levels over the past 24 hours. It is expected to stay at background levels for the next 24 hours. The greater than 2 MeV electron flux became enhanced in the past 24 hours and is expected to be at high levels over the next days following the elevated Solar wind conditions.

Solar wind speed first hovered around the 500 km/s and then decayed to under 450 km/s and is currently varying in the 450-500 km/s range. The total magnetic field was in the 3-6.5nT range with some periods of persistent orientation in Southward direction where Bz reached close to -6nT. The magnetic field phi angle was in the away sector (+) . The moderately enhanced solar wind conditions are expected to last over the next 24 hours with towards September 1 an expected onset of the high speed stream from the recurrent coronal hole that crossed central meridian on September 28. The coronal hole seems to have shrunk since last rotation and it's associated high speed stream is expected to be less pronounced as last rotation, but Solar wind speed may still reach over 600 km/s.

Geomagnetic conditions were quiet to active (K Dourbes and NOAA Kp 1-4). Geomagnetic conditions are expected to remain quiet to active in the next 24 hours with from September 1 a possibility of minor geomagnetic storming.
