NOAA AR produced only minor C-class flares, with the largest one being a C1.6 with peak at 14:00 UT on May 9. M-flares remain possible from this region.
Geomagnetic conditions have been quiet and are expected to remain so, unless the CME from May 6 arrives to the Earth and produces active conditions. The fast solar wind from a coronal hole will arrive to the Earth in about 48h.
Today's estimated international sunspot number (ISN): 109, based on 19 stations.
