Bulletin

Solar activity has slightly increased: both NOAA AR 1853/Catania 90 and NOAA AR 1850/Catania 83 produced a C1.6 flare. NOAA AR 1853/Catania 90 is ready to rotate behind the west limb, NOAA AR 1850/Catania 83 is located in the longitudinal segment between 45° and 60°. NOAA AR 1853/Catania 90 has the highest probability producing C-flares. NOAA AR 1854 (near the east limb) is new on the solar disk and is another candidate to produce C-flares, although with a lower probability. We predicted eruptive conditions, i.e. more than 50% probability for C-flares. The filament, now situated between 15° and 30° longitude is still stable. The geomagnetic conditions are quiet. Tomorrow, unsettled conditions are possible when the equatorial coronal hole becomes geoeffective.

Today's estimated international sunspot number (ISN): 031, based on 14 stations.
