Bulletin

Solar activity remains to be low. The background X-ray flux has increased to a low B-level, due to appearance of the active region which rotated from the behind of the East solar limb. This, still not numbered active region, might be the source of B-class and possibly, but not very probably, also low C-class flares in the coming hours. During last 24 hours no Earth directed CMEs have been observed and the solar protons remained at background level. The solar wind speed is presently 380 km/s, and the interplanetary magnetic field magnitude is about 9 nT. The in situ observations (from DSCOVR satellite), showed sudden increase of the interplanetary magnetic field magnitude, density, temperature and the solar wind speed at about 00:48 UT this morning, indicating arrival of a shock wave. The shock is probably associated with the large filament eruption from the north-east quadrant of the Sun, which took place in the morning of November 10. The geomagnetic conditions are quiet to unsettled and we expect them to stay so in the coming hours with the possibility of the active geomagnetic conditions starting from this evening, due to expected arrival of the fast solar wind associated with with the low latitude extend of the northern polar coronal hole (reached central meridian in the early morning of November 11).
