Bulletin

The spotless Sun was inactive with X-ray flux remaining below B level and this is expected to continue over the next days. Also proton flux levels were at background values and are expected to remain so. No Earth directed CME's were recorded in coronagraph data. A low latitude extension of the northern polar coronal hole (positive polarity) started transiting the central meridian around midnight and may influence Solar wind conditions from November 7 onwards.

Solar wind continued to be slightly enhanced with solar wind speed between 400-450 km/s. total magnetic field was in the 4-7nT range with Bz variable. Solar wind is expected to remain slightly enhanced over the next 24 hours before returning to nominal conditions. By November 7 we may see a renewed increase of solar wind conditions under the possible influence of a high speed stream from the extension of northern polar coronal hole. Geomagnetic conditions were quiet to unsettled (NOAA Kp 1-3 and local K Dourbes 0-3) and are expected to remain so over the next days.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 000, basierend auf 19 Stationen.
