Bülletään

As NOAA active region 2665 was disappearing behind the West limb it produced a final C2.8 flare peaking at 00:06UT. There are currently no spotted regions on disk and chances for C flares are very low. No Earth directed CMEs have been observed in coronagraph data. Proton flux levels are at background values and expected to remain so.

Solar wind has meanwhile declined to speeds of around 440 km/s. The large values of yesterday appear to have been observation errors. Total magnetic field is at low background values of around 2nT. Some perturbations in the solar wind conditions may occur over the next days, due to sector boundary crossings and the possible influence of the extension of the northern polar coronal hole. Geomagnetic conditions were quiet (local K Dourbes and NOAA Kp 0-2). Geomagnetic conditions are expected to become quiet to unsettled with an isolated active period possible as some minor perturbations in the solar wind could occur over the next days.
