Bulletin

Solar X ray flux remained below B level throughout the period. There are no active regions on disk and X-ray flux is expected to remain at background levels.

No Earth-directed CME's were detected in coronagraph images.

Solar high energy proton fluxes were at background levels and are expected to remain so.

Solar wind parameters showed this morning the expected arrival of the compression region ahead of the recurrent high speed stream. Total magnetic field reached a peak over 13nT around 9UT. The Bz was mostly negative with peaks down to -11nT. The magnetic field phi angle remained in the negative sector before switching to the positive sector around 11UT. The Solar wind speed increased to over 520km/s and is still rising. The Solar wind speed is expected to further increase and remain elevated for the next 24-48 hours before starting to subside.

Until just recently, geomagnetic conditions were quiet (NOAA Kp and local K Dourbes 0-2). The latest synoptic period 9-12UT showed active geomagnetic levels (NOAA Kp and local K Dourbes 4) as expected under the Solar wind perturbations. Geomagnetic conditions are expected to be active with minor geomagnetic storms and possibly a moderate geomagnetic storm period over the next 24-48 hours, before easing to unsettled to active levels.
