Bulletin

The spotless Sun was inactive with X-ray flux remaining below B level and this is expected to continue over the next days. Proton flux levels were at background values and are expected to remain so. No Earth directed CME's were recorded in coronagraph data.

Solar wind returned to nominal with solar wind speed 450 km/s at the start of the period and around 375 km/s at the end of the period. Total magnetic field was near nominal 4-6nT values with Bz variable. Solar wind is expected to remain nominal over the next 24-48 hours, while by November 7 we can expect to see a renewed increase of solar wind conditions under the influence of a high speed stream from the extension of the northern polar coronal hole. Geomagnetic conditions were quiet (NOAA Kp 0-1 and local K Dourbes 0-2) and are expected to remain so over the next days before becoming enhanced on November 7 due to the influence of the expected high speed stream.

Estimation du nombre international de taches solaires (ISN) pour aujourd'hui : 000, sur la base de 17 stations.
