Solar activity was low with 2 low level C flares. A C1.3 flare peaking at 04:04UT originated from the new region in the northern hemisphere (now numbered NOAA 2351) and a C1.6 flare peaked at 8:12UT from region 2349. All regions on disk appear fairly simple. Quiet conditions are expected with a chance for isolated low level C flares. Again a number of small eruptions were recorded: one from around 25N20W between 02:00UT and 03:00UT, and one associated to the C1.6 flare from region 2349. Although neither of those appears particularly threatening, no coronagraph data were available yet to assess possible Earth directed components. Solar wind conditions are determined by a high speed stream from a positive polarity coronal hole. Solar wind speed seems to have reached its maximum early in the reporting period with speeds at that time fluctuating around 550 km/s which have since decreased to current values around 490 km/s. The total magnetic field restored to fairly nominal values of 6nT just after the start of the reporting period and remained stable. Bz was variable in that range. Geomagnetic conditions were quiet to unsettled (both NOAA Kp and local K Dourbes 1-3). With the expected further decline of the high speed stream influence and nominal magnetic field strengths, geomagnetic conditions are expected to remain at quiet to unsettled levels.
