Bulletin

Solar conditions were quiet with X-ray flux at background level. All four regions on disk were inactive and either stable or decaying. Solar conditions are expected to remain at very low levels. Proton flux levels were at background levels and expected to remain so. An equatorial negative polarity coronal hole is currently transiting the central meridian and may become geoeffective 3 days from now. No Earth directed CME's have been observed in coronagraph data.

Solar wind conditions were near nominal with solar wind speed fluctuating around 400 km/s and total magnetic field around 5 nT with a declining tendency. The magnetic field phi angle was in the negative sector throughout the period. Solar wind conditions are expected to remain nominal with later tomorrow afternoon October 13 the possible passage of the October 9 CME which should only involve a small velocity increase, but may be accompanied with magnetic field perturbations. Geomagnetic conditions have been quiet (local K Dourbes 0-2, NOAA Kp 0-1). Geomagnetic conditions are expected to remain quiet to unsettled with later, starting tomorrow afternoon October 13, possibly minor to moderate geomagnetic storm levels associated with the possible CME arrival.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 039, basierend auf 07 Stationen.
