Bulletin

Solar activity is extremely low, with no C-class flares reported since December 10. We expect solar activity to stay at the same level with the low probability for the isolated C-class flares. No Earth directed CMEs were observed in the last 24 hours.

The solar wind speed is slowly decreasing and it presently amounts about 470 km/s. The interplanetary magnetic field magnitude is about 4nT. The fast solar wind associated with the small equatorial coronal hole which reached the central meridian in the morning of December 12 is expected to arrive at the Earth in the midday of December 15. It might be closely followed in arrival time by the fast flow from the small coronal hole (between S08 and S12) which reached the central meridian early on December 13. The geomagnetic conditions are presently quiet. We expect unsettled to active conditions, due to expected arrival of the fast solar wind, starting from midday tomorrow.

Today's estimated international sunspot number (ISN): 023, based on 17 stations.
