Bulletin

The solar activity is low. The strongest of three C-class flares reported during last 24 hours was the C2.5 flare (peaked at 05:15 UT) on October 12. All three C-class flares originated from the NOAA AR 2187 which is currently situated close to the east solar limb. No Earth directed CMEs were observed in last 24 hours. The flaring activity at the C-class level is possible, in particular from the NOAA AR 2187. The Earth is currently inside a slow solar wind with the speed of 340 km/s, and the interplanetary magnetic field magnitude has the average value of about 4nT. We expect quiet to unsettled geomagnetic conditions to continue in the following hours.

Today's estimated international sunspot number (ISN): 022, based on 13 stations.
