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 continue to be below C level.

No earth directed CMEs have been recorded.

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

Solar wind was nominal at the start of the period but Solar wind increased overnight to around 400 km/s presently with a simultaneous increase in magnetic field marking the influence of the equatorial coronal hole that passed central meridian January 9. Total magnetic field shortly peaked at 11nT with Bz reaching close to -9nT but otherwise variable. Solar wind is expected to remain somewhat enhanced with more solar wind enhancements expected from late tomorrow January 15 onwards as the current effects will be followed by those of the coronal hole that passed central meridian midnight January 12/13.

Geomagnetic conditions were quiet (local K Dourbes and NOAA Kp 0-2). Quiet to unsettled conditions with isolated active periods are expected over the next days.

Estimation du nombre international de taches solaires (ISN) pour aujourd'hui : 000, sur la base de 18 stations.
