Solar activity was low but with several low C class flares were recorded over the period. The biggest event was a slow rising long duration C3.2 flare from at or behind the West limb peaking at 14:29UT. More C flares originated from regions NOAA 2435, 2436, 2437 and from the East limb. NOAA region 2439 (Catania 58) disappeared during the period while two new groups formed to the East, now numbered NOAA 2441 and 2442. New flux emergence was also recorded in the north of NOAA region 2437 (Catania 55). Flaring at C level is expected to continue, with also a chance for an M flare. The C3.2 flare was associated with a westbound CME which is not expected to be geoeffective. The CME associated to the C2.1 flare of October 26 seems to be rather narrow and not particularly fast. It is not expected to have much influence on Earth. Solar wind speed decreased from around 370 km/s to around 330 km/s. Total magnetic field was mainly in the 4-5.5 nT range and recently dropped to 3 nT. Bz was first negative and later positive, and never significantly below -4nT. The phi angle showed a sector change from positive to negative around 1:00UT. Geomagnetic conditions were quiet (both local K Dourbes and NOAA Kp 0-2). Nominal solar wind conditions and associated quiet to unsettled geomagnetic conditions are expected to continue.
