Bulletin

X-ray flux remained below B level. With a spotless disk, again X-ray flux is expected to remain below C level.

No new Earth directed CME's have been detected in coronagraph data.

The Solar proton flux levels were at background values and are expected to remain so.

An equatorial coronal hole of positive polarity has crossed the central meridian overnight. It may influence the Solar wind from around late March 18.

Solar wind first saw a gradual slight increase of total magnetic field towards 8.5nT with a predominantly negative Bz component (peaking under -6nT) while other parameters remained stable with a Solar wind speed of 340 km/s. At 6:17UT a slow forward shock occurred, with speed jumping to around 400 km/s, while total magnetic field dipped down to around 4.5nT. Solar wind speed is now around 380 km/s. Solar wind conditions may further enhance later in the day under influence of the equatorial coronal hole that crossed central meridian late March 10. Towards March 17 there is a small possibility of some slow CME transients associated to the March 12 CME.

Geomagnetic conditions were quiet to unsettled (both NOAA Kp and local K Dourbes 1-3). Geomagnetic conditions are expected to become unsettled with a possibility for active periods under high speed stream influence.
