Solar activity was low. Only some low level C class flares were reported with the largest event a C3.9 flare from NOAA 2277 (Catania 78, 79) peaking at 10:53 UT. NOAA 2268 (Catania 73, 74), Catania 80 (now numbered NOAA 2279) and the new region in the east: Catania 82 (NOAA 2280) all contributed to the other C flares. We expect some further low level C flaring with still a chance for an isolated M flare from NOAA 2277. No obvious CMEs were recorded. Earth was under the influence of a steady high speed stream. Solar wind speed was largely in the 600 to 740 km/s range with on average a slow decrease over the period. Since 7:00 UT the decrease of the solar wind speed is more pronounced with currently values of around 560 km/s. The total magnetic field was mainly in the 3 to 6 nT range. Bz was variable with negative peaks not below -5.5nT. High speed stream conditions are expected to further decline to nominal wind conditions over the next 24 hours. Active geomagnetic conditions with locally an isolated episode of minor geomagnetic storm conditions were reported (NOAA Kp 2-4, local KDourbes 2-5) under the influence of the high speed stream. With the decline of the high speed stream influence quiet unsettled geomagnetic conditions are expected with initially still a chance for a active conditions.
