Bulletin

Solar activity was very low with X-ray flux remaining below B level. A new bipolar active region (NOAA 2723) emerged but is inactive. Chances for X-ray flaring are thus increasing but X-ray flux is still expected to be below C level.

No Earth directed CMEs have been recorded in coronagraph images.

Proton flux levels were at background values and are expected to remain so.

A negative polarity equatorial coronal hole is currently transiting the central meridian and is expected to become geoeffective by late October 3.

Solar wind saw some transient perturbations with solar wind speed reaching 500 km/s and total magnetic field reaching 8nT. Bz was mostly positive. Currently, Solar wind speed is back at near 430 km/s and total magnetic field at a nominal 2-4nT. Near nominal solar wind conditions are expected over the next days.

Geomagnetic conditions were quiet to unsettled (both NOAA Kp and local K Dourbes 0-3). Geomagnetic conditions are expected to be quiet to unsettled over the next days.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 016, basierend auf 22 Stationen.
