Bulletin

Solar activity was low to moderate during the past 24 hours. In total, eight active regions are visible on the disk, but only two of them present a risk for isolated C class flares: NOAA AR 1769 and 1775. Current interplanetary conditions are quiet, and we expect the geomagnetic activity to stay at quiet levels for the next 48 hours.

Today's estimated international sunspot number (ISN): 064, based on 09 stations.
