Bulletin
Solar activity was very low with X ray flux remaining below B level. There are no spotted regions on disk and X ray flux is expected to remain at background levels.
No Earth directed CMEs have been detected in coronagraph data.
The solar proton flux levels are at background values and are expected to remain so.
The solar wind is in a slow wind regime. Solar wind speed is between 340-400 km/s with total magnetic field 3-6nT.
Nominal Solar wind conditions are expected over the next days, until May 6 when the influence of the equatorial coronal hole is expected to increase solar wind conditions.
Geomagnetic conditions were quiet (local K Dourbes 0-2 and NOAA Kp 0-1) and are expected to remain quiet until May 6 when the influence of the equatorial coronal hole is expected to raise geomagnetic conditions to active or minor storm levels.
