Bulletin

The strongest flare observed during last 24 hours was M1.0 flare (peaked at 02:33 UT, on November 15), originating from the NOAA AR 1899. We expect C-class flares and possibly also M-class flares in the coming hours. The solar wind speed is about 350 km/s and the interplanetary magnetic field magnitude is 4 nT. The Bz component of the interplanetary magnetic field is fluctuating about -4nT during last 12 hours what might result in the unsettled to active geomagnetic conditions. The arrival of the fast flow associated with the low-latitude coronal hole in the northern hemisphere is expected to result at most in active geomagnetic conditions.

Today's estimated international sunspot number (ISN): 115, based on 09 stations.
