Bülletään

Solar activity was at very low levels and is expected to remain so.

No Earth-directed Coronal Mass Ejections (CMEs) were observed in the available coronagraphic imagery.

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 exceeded the threshold value of 1000 pfu for much of the reporting period. It is expected to continue to be at high levels during the coming days.

The solar wind speed showed a decreasing trend, reducing from 640 km/s at the start of the period to around 500 km/s by the end. The total magnetic field remained below 5 nT. Bz was predominantly negative with a minimum value of -4 nT. The direction of the interplanetary magnetic field (phi angle) was initially directed away from the Sun (positive sector) but switched to the negative sector for an extended period between 14 to 23 UT Sep 01 and then continued to oscillate between the two sectors. Although still enhanced, the solar wind conditions are expected to slowly return to nominal conditions from Sep 03 as the influence from the high-speed stream reduces.

Geomagnetic conditions were at quiet to active levels (K Dourbes and NOAA Kp recorded values of 2-4 and 2-3, respectively). Geomagnetic conditions are expected to be quiet to unsettled during the next 24 hours with a possibility of a further isolated active interval.
