Solar flaring activity was at low levels with region 2403 producing the only noteworthy flare of the period, a C2.2 flare peaking at 5:22UT from at the West limb. New flux emergence was noted near N15W48 as well as near S15E70 which were numbered NOAA active regions 2407 and 2408 repectively. Some more flux emergence appears to be visible near N15W10. The regions currently on disk are not very complicated or active, but together with also the new emerging regions developing we judge that there do remains a fair chance for C flaring in the next 24 hours. The warning condition for a proton event is lifted with the departure of active region 2403 behind the West limb. No Earth directed CME's were recorded. Solar wind showed the decay of the influence of the negative polarity equatorial coronal hole high speed stream. Speeds dropped to around 390 km/s. Total magnetic field was around 5 nT with Bz variable. Geomagnetic conditions were quiet at planetary level (NOAA Kp 1-2) with some unsettled periods locally (local K Dourbes 0-3). A further decay to nominal solar wind conditions and associated quiet geomagnetic conditions is expected in the first 24 hour. Afterwards, a sector boundary crossing followed by the influence of the positive polarity equatorial coronal hole high speed stream is expected to elevate solar wind conditions with active to minor geomagnetic storms possible.
