Bulletin
Solar X-ray flux remained below B level. With no regions on disk chances for C-class flaring are very low.
No Earth directed CMEs have been observed in coronagraph images.
Proton flux levels were at background values and are expected to remain so.
Solar wind was near nominal with solar wind speed fluctuating in the 340-400 km/s range and total magnetic field in the 3-6nT range. The magnetic field phi angle is still in the negative sector. Near nominal conditions are expected over the next days.
Geomagnetic conditions were quiet (local K Dourbes 0-2 and NOAA Kp 0-1) and are expected to remain so.
