公告

Solar activity has been active during the past 24 hours, with an M2.2 flare and two C flares. The M flare peaked at 17:48 UT on April 5, and was produced by new NOAA AR 11719 on the East limb. More C flares are expected within the next 48 hours, with a good chance for an M flare, especially from NOAA AR 11719 and 11718. Solar wind speed as measured by ACE has been steadily increasing from about 260 km/s in the second part of April 5 till about 360 km/s around 12h UT on April 6. This could be due to the arrival of an expected coronal hole high speed stream. A further increase of the solar wind speed is possible on April 6. Geomagnetic activity was at quiet levels (NOAA Kp between 1 and 2) during the past 24 hours. Quiet (K Dourbes < 4) conditions are predicted for April 6 to 8 with a slight chance for active periods due to the possible arrival of a coronal hole high speed stream.
