Solar activity was low. The strongest flare of the period was a C9.7 flare peaking at 8:17UT from Catania group 50 (NOAA AR 2257). Apart from that, only some minor C flaring occurred. Catania group 50 (NOAA AR 2257) continued to grow in size and complexity. Flux emergence and separation was recorded in Catania group 56 (so far NOAA unnumbered). Other regions were relatively stable. Flaring at C level can be expected over the coming days with also a chance for an M flare. No Earth directed CME's were recorded. Solar wind speed was mainly in the 420 to 520 km/s range with a peak over 550 km/s Total magnetic field declined steadily from over 9 nT to around 5 nT. Bz was variable with some negative peaks below -7nT. The geomagnetic conditions were quiet to unsettled (NOAA Kp 2-3, local K Dourbes 1-3). Solar wind parameters are expected to decline further as the influence of the coronal hole high speed stream diminishes. Geomagnetic conditions are expected to be quiet to unsettled with initially still some active period possible.
