Bülletään

Both sunspot groups, which were observed on the visible side of the solar disc during last 24 hours, are decaying. Solar flaring activity was low and will remain so in the coming hours with very low probability for C-class flares (about 5%). There were no Earth directed CMEs observed since last report, and the solar protons remained at background level.

The Earth is within the slow solar wind (speed of about 360 km/s) and the interplanetary magnetic field magnitude is very low presently amounting about 1 nT. The fast solar wind associated with the large equatorial coronal hole (reached central meridian in the early morning of November 16) is expected to arrive at the Earth later today. The geomagnetic conditions are presently quiet and we expect unsettled to active geomagnetic conditions starting from this evening, due to the expected arrival of the fast solar wind.
