公告

Solar activity has been active during the past 24 hours, featuring one M1.4 flare released by NOAA AR 11739on May 5 with peak time 17:56 UT. In addition, 13 C flares were registered. More C-level flares are expected within the next 48 hours, with a chance for an M flare from AR 11739 and 11734. The IMF started rising at about 7h UT on May 5 (4 nT), and has been turbulent since about 15h UT on May 5. Current values lie around 12 nT, but no large negative excursions of Bz occurred since then. Solar wind speeds as observed by ACE started a turbulent rise at about 15h UT on May 5 (400 km/s), and are now near 520 km/s. These effects are probably caused by a co-rotating interaction region followed by a positive-polarity coronal hole high speed stream. The influence of this high speed stream is expected to decrease on May 7. Geomagnetic activity was at quiet to active levels (K Dourbes between 0 and 4; NOAA Kp between 1 and 3) during the past 24 hours. Quiet to Active (K Dourbes < 5) conditions are expected for May 6 to 8.
