Bulletin

Flaring activity in the past 24 hours reached only the B-class level. The most dynamic active region on the disk is NOAA AR 2473 (beta- gamma, Catania nr 5). As this active region is increasing in shear and complexity, we expect a return to C-class flaring with 40% chance for an M-class flare. A smaller chance for C-class flaring is also possible from AR 2472 (beta, Catania nr 4). The Earth is currently inside a solar wind flow with an intermediate speed (around 550 km/s). The interplanetary magnetic field magnitude is average(5-6 nT). These conditions are expected to persist in the coming 48 hours, geomagnetic activity is expected to remain below Kp=4.

Today's estimated international sunspot number (ISN): 057, based on 16 stations.
