While NASA says that former region AR2673 is scheduled to return September 20 (today) through the 23, Belgium says that it is AR2676 that has already returned this morning and is actively B flaring with a chance of C flares. Both Active Regions are in the Southern Hemisphere.
This returning active region AR2676 appears to have an alpha configuration, but more will be revealed as it comes fully over the limb.
However, I am beginning to wonder if AR2676 is being confused for AR2673.
The newly returned AR2676 has been newly renamed AR2681, which is now located at S12E73.
AR2673 has had an S09 latitude. and one would expect that it would remain at that same S09 latitude when it returns, but NOAA is showing that AR2676 had an S09 latitude. Obviously, someone has made a typographical error.
