Bulletin

Solar activity has been low, only one C-class flare in past 24 h: a C2.4 flare that peaked at 09:22 UT from NOAA AR 2539 (Catania 66 and 67). Six active regions are visible on the disk, three of them with beta magnetic field configuration and the rest with alpha magnetic field configuration of their photospheric field. C-class flaring is likely for the next 24 h.

Geomagnetic conditions have been quiet. Solar wind speed is at 375 km/s with interplanetary magnetic field magnitude of 10 nT. Active conditions (with isolated minor storm periods) are expected when the fast speed stream from a coronal hole arrives to the Earth later today.

Today's estimated international sunspot number (ISN): 085, based on 13 stations.
