Bulletin

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 was above the threshold value of 1000 pfu for the entire reporting period, with a maximum value of 14200 pfu reached at 16:20 UT Sep 03. It is expected to remain at high levels during the coming days.

The solar wind speed varied between 410 and 460 km/s over the period. The total magnetic field fluctuated around 4nT. Bz had a minimum value of -5 nT. The interplanetary magnetic field was predominantly directed away from the Sun (phi angle in the positive sector). The solar wind conditions are expected to be at nominal levels over the coming days.

Geomagnetic conditions were quiet to unsettled (K Dourbes and NOAA Kp recorded values of 0-2 and 0-3, respectively). Geomagnetic conditions are expected to be quiet over the next 24 hours with isolated unsettled periods possible.

Today's estimated international sunspot number (ISN): 000, based on 22 stations.
