Bulletin

Solar X ray flux remained below B level throughout the period. The Solar disk is spotless and X-ray flux is expected to remain at or below background levels.

There were no Earth-directed CMEs observed in coronagraph data.

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

Solar wind conditions were nominal. Solar wind speed declined from around 420 km/s to around 380 km/s. Total magnetic field was below 4nT and the magnetic field phi angle was mostly in the positive sector. Near nominal Solar wind conditions are expected over the next 48 hours.

Geomagnetic conditions were quiet to unsettled (NOAA Kp 1-3 and local K Dourbes 0-3). Quiet geomagnetic conditions are expected over the next 48 hours.

Today's estimated international sunspot number (ISN): 000, based on 24 stations.
