Bulletin

Quiet solar conditions were reported with the X-ray flux touching only briefly into the B level. Both active regions on disk are relatively simple (Mag.Type: Alpha) and quiet. The X-ray flux is expected to remain below C level. Proton flux levels were at background values and are expected to remain so. No Earth directed CME's were recorded in coronagraph data. A negative polarity low latitude coronal hole is starting its transit of the central meridian on the Southern hemisphere. It may influence Solar wind conditions starting 3 days from now.

Solar wind conditions were nominal with Solar wind speed decreasing to below 350 km/s while total magnetic field was mostly in a nominal 2-4nT range with the Bz component variable. The phi angle indicated connection to a positive sector. Nominal Solar wind conditions are expected over the next days. By noon November 1 the high speed stream from the southern, low latitude coronal hole and the sector boundary change preceding it could potentially enhance Solar wind conditions. Geomagnetic conditions were quiet (local K Dourbes 1, NOAA Kp 1-2) and are expected to remain so over the next days.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 024, gebaseerd op 15 stations.
