Bülletään

Solar activity was very low with X ray flux level remaining below B level. There are no spotted regions on disk and Solar flaring is expected to remain below C level over the next days.

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

The greater than 10 MeV proton flux was at nominal levels over the past 24 hours and is expected to stay at nominal levels. The greater than 2 MeV electron flux was at background to moderate levels the past 24 hours and is expected to remain so.

Solar wind showed some enhancement since late yesterday, following a switch of the magnetic field phi angle into the positive sector. This possibly indicates connection with the Solar wind from the isolated equatorial coronal hole that passed central meridian April 1-3. Solar wind has meanwhile increased to around 410 km/s. Total magnetic field also became elevated reaching to 10nT, with a variable Bz component attaining peaks of down to -9.7nT. Solar wind conditions may remain slightly elevated over the next days but more significant enhancements are expected by April 11, due to the low latitude extension of the southern polar coronal hole currently transiting the central meridian.

Geomagnetic conditions were quiet to unsettled (NOAA Kp and local K Dourbes 0-3). Unsettled conditions are expected over the next days with possibly some isolated active periods. By April 11, active conditions are expected with possibly minor geomagnetic storm periods.
