公告

Solar activity was low. Several low level C class flares occurred, originating from NOAA regions 2277, 2280 and 2282. The largest event was a C3.7 flare from NOAA active region (AR) 2282 peaking at 06:07UT. NOAA AR 2280 has shown some growth over the period. AR 2282 has rotated on disk, at approx N15 on the East limb and has shown signs of activity with some flows around 05:30UT. Flaring is expected to continue at C level. No Earth directed CMEs have been observed. Solar wind speed is decreasing, and has decreased from approx 600 km/s to 450 km/s. The density has seen a small increase and there is a small rotation in the magnetic field. We expect quiet geomagnetic conditions to continue.
