Bülletään

Solar activity was very low with a single minor B flare from the plage region turning around the West limb. There are no spotted regions on disk and X ray flux is expected to remain at background levels.

No Earth directed CME's were observed in coronagraph data.

Solar proton flux levels were at background values and are expected to remain so.

An equatorial negative polarity coronal hole is starting to transit the central meridian this afternoon. It is expected to influence solar wind conditions from May 6 onwards.

Solar wind saw a further steady decline of the velocity to values of under 400 km/s since after midnight. Total magnetic field remained between 4.5 and 6.5 nT with a variable Bz. 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 1-2 and NOAA Kp 0-2) 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 levels.
