Bülletään

Solar X ray flux remained below B level throughout the period. With a spotless disk, 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 slightly increasing to between 400-450 km/s and total magnetic field in the 2-7nT range. The magnetic field phi angle switched to the positive sector around 20:30UT. There was a possibility of enhanced solar wind conditions under the possible influence of a negative polarity coronal hole in the southern hemisphere, but this does not seem to occur. Solar wind conditions are expected to remain near nominal.

Geomagnetic conditions were quiet to active (NOAA Kp and local K Dourbes 1-4). Geomagnetic conditions are expected to be quiet to unsettled with initially an isolated active period still possible.
