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 speed varied around 400 km/s with peaks over 440 km/s and down to 350 km/s. Total magnetic field declined from around 8nT to background values between 2-5nT, with Bz variable and not below -3.5nT and with a magnetic phi angle in the negative sector. Solar wind conditions are expected to be close to nominal over the next days.

Geomagnetic conditions were quiet (both local K Dourbes and NOAA KP 0-1). Quiet geomagnetic conditions are expected over the next days.

Today's estimated international sunspot number (ISN): 000, based on 10 stations.
