Solar activity was low with several C flares all remaining below C3 class. The largest peaked at C2.7 level at 4:06UT from the new region on the East limb, now marked Catania group 92. Although in the hour before this event the X ray flux was already elevated due to C flaring activity from NOAA region 2360 from beyond the West limb. Further low level C flaring from both regions was observed throughout the period. Catania group 87 (NOAA 2367) is the most complex group on disk. Some oposite flux emergence was observed in the leading part of Catania group 91 (NOAA 2369). Further flaring at C level is expected with also a chance for M flaring. No Earth directed CMEs were recorded. Solar wind showed the continued, but declining, influence of the positive polarity coronal hole high speed stream. Solar wind speed decreased from around 600 km/s to around 500 km/s. Total magnetic field increased slightly to a peak of around 8nT, and currently again at 6 nT level. Bz was variable, but mostly negative, though not below -6nT. Geomagnetic conditions were quiet to active (NOAA Kp 2-4 and local K Dourbes 1-4) with only an isolated period of active conditions yesterday afternoon. The high speed stream influence is expected to further decline, with corresponding quiet to unsettled geomagnetic conditions, although initially an isolated active period may still be possible.
