Bulletin

Solar X ray flux remained below B level and with no spotted regions on the visible disk chances for any flare occurrences remain very low.

No new Earth directed CMEs have been observed in coronagraph data.

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

Solar wind became nominal with solar wind speed declining from 400 km/s to 350 km/s and total magnetic field under 6nT. The magnetic field phi angle mostly indicated connection with a positive sector. Solar wind may again increase under the influence of the low latitude extension of the positive polarity northern polar coronal hole. After noon tomorrow March 9, there is a small possibility of minor perturbations associated to the possible passage of the ejecta of March 6. The possible passage of the ejecta of March 7, should not be expected before noon March 10. All those impacts are expected to be fairly minor, if identifiable at all.

Geomagnetic conditions were quiet (both local K Dourbes and NOAA Kp 0-2). Geomagnetic conditions are initially expected to be quiet to unsettled. From noon March 9 onwards an increase to active conditions can not be excluded should any of the mentioned ejecta arrive at Earth and carry a distinctive southward directed magnetic field.
