A large prominence lifted off the northwest limb on July 21, 2013 and generated a Coronal Mass Ejection (CME), directed to the north and away from Earth.

Solar activity is generally low past few days. There are currently 4 numbered sunspots on the visible solar disk .Majority of the flares originated from AR 1800 which has, at the moment, beta-gamma-delta configuration of the photospheric magnetic field. The strongest flare was C3.1 which peaked at 08:44 UTC on July 21, 2013. NOAA/SWPC forecasters estimate low 10% chance of M-class solar flares.
Earth is still inside a solar wind stream flowing from the huge coronal hole located at northern hemisphere.
