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.

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

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

A recurrent equatorial positive polarity coronal hole is about to rotate across the central meridian and is expected to influence solar wind parameters later this week.

Solar wind conditions were nominal. Solar wind speed was between 320-360 km/s and total magnetic field was below 6.5nT with a variable Bz. The magnetic field phi angle switched to the negative sector after 18UT but was unstable with regular excursions back into the positive sector. Solar wind conditions are expected to become slightly enhanced under the elevated solar wind speeds associated to a negative polarity coronal hole.

Geomagnetic conditions were quiet to unsettled (NOAA Kp 1-3 and local K Dourbes 0-3). Geomagnetic conditions are expected to be unsettled with active periods possible over the next 24-48 hours under the expected enhanced Solar wind conditions.
