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 speed reached a maximum of around 420 km/s before declining to current values around 370 km/s. Total magnetic field was around a nominal 5nT with the phi angle mostly in the negative sector. Solar wind conditions are expected to remain nominal over the next 24 hour and then are expected to become enhanced from late December 17 or early December 18 under the influence of the equatorial positive polarity coronal hole.

Geomagnetic conditions were quiet to unsettled with both local K Dourbes and NOAA Kp reaching an isolated period of K=3. Geomagnetic conditions are expected to remain quiet to unsettled over the next 24 hours with later unsettled to active conditions from December 18 onwards, with also a possibility of isolated minor geomagnetic storm episodes.
