Solar activity was low with no flares reported and Catania group 9 (NOAA region 2734), the only region on disk, in decay. Overall probability for flaring at C level remains low.

No 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.

Solar wind was at near nominal conditions until around 5:44 UT this morning when speed jumped to around 400 km/s and magnetic field orientation changed abruptly, both in terms of magnetic field phi angle and in terms of Bz turning Southward (-8nT) marking the arrival of the March 8 CME. Since then, total magnetic field reached a peak of 10nT and Bz saw a somewhat prolonged period of negative Bz (around -8-9nT) rotating slowly back into positive values currently. CME influences seem to be decaying but further disturbances can still occur in its wake. By the morning of March 14, we may see renewed solar wind enhancements from the equatorial coronal hole that passed central meridian late March 10.

Geomagnetic conditions were first quiet and later unsettled with the CME arrival (local K Dourbes and NOAA Kp reaching 3). With the main core of the CME passed, geomagnetic conditions are expected to remain quiet to unsettled in its wake.
