Bulletin

Several C-class flares in past 24h, the strongest being a C4.5 flare peaking at 17:58 UT on October 13, from NOAA AR 1861 (beta gamma magnetic field configuration). This AR, and in particular AR 1865 (beta-gamma- delta), can produce M-class flares in the next 48h. Geomagnetic conditions are currently unsettled due to the arrival of a fast speed stream from a coronal hole. The solar wind speed is at 500 km/s with magnetic field intensities currently at 7 nT. Conditions may reach active levels.

Today's estimated international sunspot number (ISN): 097, based on 09 stations.
