Bülletään

Solar activity was very low during the period. The X-ray flux remained below C level and no significant flaring has been recorded. The spotted regions on disk showed no significant development. Flaring at C level is not expected over the next period although it remains possible, mostly due to Catania group 25 (NOAA 2505). No Earth directed CMEs have been recorded. Solar wind was in a low speed regime with velocity in the 300-400 km/s range. Total magnetic field increased during the period reaching almost 8 nT. The North-South component of the magnetic field was mostly negative (south), and the magnetic field phi angle was now more clearly in the negative sector. Quiet geomagnetic conditions with some periods of unsettled conditions in response to the negative Bz values were recorded. (both local K Dourbes and NOAA Kp 1-3). Nominal solar wind conditions with associated quiet geomagnetic conditions are expected to continue. Although the possible influence of a weak high speed stream from the extensions of the Northern polar coronal hole may, from later today onwards, slightly increase solar wind conditions leading possibly to more unsettled geomagnetic conditions.
