Bulletin

Quiet solar conditions were recorded with only a minor B1.5 flare from NOAA region 2610. Regions 2609 and 2610 showed some slight growth but remain rather simple and fairly stable . There is just a small chance for C flares from either of those regions. The solar proton flux was at background levels and expected to remain so. No Earth directed CMEs have been recorded in coronagraph data. Solar wind conditions are still under the influence of the coronal hole high speed stream but are starting to see recovery towards nominal conditions. Solar wind speed showed an overall decaying trend starting in the range 650-700km/s and ending in the range 600-650km/s. Total magnetic field remained around 5nT with a variable North-South component. The magnetic field phi angle is in the negative sector. Solar wind should see a further recovery towards nominal conditions over the next days. Geomagnetic conditions were quiet to active (NOAA Kp 2-4, local K Dourbes 1-4). As solar wind is further declining geomagnetic conditions are expected to be unsettled with initially a chance for an isolated active period and later becoming quiet to unsettled.

Today's estimated international sunspot number (ISN): 029, based on 04 stations.
