Bulletin

Solar activity is low, with only few B-class flares reported during last 24 hours. We expect solar activity to stay at the same low level with possible, but not very probable isolated C-class flares from the active region which started its rotation from the behind of the east solar limb. No Earth directed CMEs have been observed and the solar protons remained at background level in the past 24 hours. The Earth is inside the slow solar wind with the speed of about 400 km/s. During last 24 hours the interplanetary magnetic field magnitude was stable having the value of about 3nT. The geomagnetic conditions are quiet and we expect quiet to possibly unsettled and even active geomagnetic conditions starting from tomorrow afternoon. The expected disturbed geomagnetic conditions are associated with the low latitude extend of the northern polar coronal hole (reached central meridian in the early morning of November 11).
