As sunspot region 3664 rotates away (it lobbed a parting flare at X3.4 at 08:37 UTC), other sunspot regions are rotating into view.
A new sunspot region rotating in from the other side emitted an X2.9 flare today at 14:38 UTC. It will not affect earth much but SWPC will be keeping an eye on such sunspots and flares as they rotate further and line up in the direction of earth.
Note that the Sun has a synodic rotation period of 26.24 days at the equator.
