Bülletään

Solar activity has been low, NOAA AR 1748 produced a C6.0 flare with peak at 03:45 UT. This remains the most active region, although it is decreasing in complexity, and may lose its delta configuration soon. M-class flares can be expected, and X-class flares remain possible. Proton levels are decreasing, but are still slightly over the threshold for 10 MeV. A shock arrived to the Earth at 00:30 UT, it corresponds to the CME from May 15. It arrived later than expected, which can happen for glancing blow events. A short sheath was seen right after the shock. A solar wind speed of 450 km/s and Bz up to -15 nT caused Kp = 5, between 00:00 UT and 06:00UT, while the local Dourbes K value went up to 4. The CME from May 17 is expected to arrive around noon on May 19 and cause up to major geomagnetic storms.
