Bulletin
Three C-class flares today, the strongest one was a C1.8, all of them originated in NOAA 2535 (Catania 63). More C-class flares are likely.
Geomagnetic conditions have been quiet. The solar wind speed is at 450 km/s with interplanetary magnetic field magnitude around 5 nT. The fast solar wind from a coronal hole will arrive to the Earth in about 48 h. Until then, quiet geomagnetic conditions are expected.
Today's estimated international sunspot number (ISN): 094, based on 20 stations.Solar indices for 27 Apr 2016
