Bülletään

Solar X ray flux remained below B level throughout the period. The Solar disk is spotless and X-ray flux is expected to remain at or below background levels.

There were no Earth-directed CMEs observed in coronagraph data.

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

Solar wind conditions were near nominal with Solar wind speed around 350 km/s and total magnetic field in the 4-6nT range. The Bz component evolved from negative to positive over the period and the magnetic field phi angle was persistently in the positive sector. Solar wind conditions are expected to remain nominal in the next 24 hours and then become enhanced by late September 23 due to the high speed stream from an equatorial coronal hole. Solar wind speed is then expected to reach over 500 km/s.

Geomagnetic conditions were quiet (NOAA Kp 0-2). Geomagnetic conditions are expected to remain quiet for the next 24 hours, and then increasing by late September 23 to unsettled conditions with also some active periods due to the high speed stream solar wind enhancements.
