Solar activity was low. The X ray flux initially only briefly touched the C level with a C1 flare from Catania group 54 (NOAA 2436) peaking at 5:14UT. However, just before the end of the reporting period X-ray flux increased due to an ongoing C1.5 flare (peak at 12:11 UT) from a region at or beyond the East limb. The new Catania group 56 (NOAA 2440) grew as it was passing the central meridian with also another sunspot group (Catania 57) emerging behind it. Flaring is expected at C level mainly from the new regions, Catania 54 (NOAA2436) and the unnumbered region at the East limb. Yesterdays C2.1 flare seems to have caused a CME off the West limb, however currently available coronagraph images do not yet allow a conclusive analysis of its extent. Solar wind speed saw a gradual decline from around 480 km/s to 360 km/s. Total magnetic field also declined from around 6.8 nT to around 5 nT. Bz was between -3.5 nT and 4.4 nT. The magnetic field phi angle was stable in the positive sector. Geomagnetic conditions were quiet (both local K Dourbes and NOAA Kp 0-2). Solar wind conditions are expected to remain nominal with associated quiet geomagnetic conditions.
