So, what "FORMERLY TY SGE" actually refers to is an identification error in the former AAVSO charts? Am I correct to interpret that this doesn't imply that the true identification of TY Sge is recently recovered (as in GM Sgr and V4641 Sgr)? [But if this is the case, I wonder why the AAVSO don't use a more specific (at least better...) name such as SGETYVAR rather than SGEVAR.] We have a number of "TY Sge" observations reported to the VSNET. The observers are: Poyner, Vanmunster, Diepvens, Taylor, Commelo and Simonsen. Should all these observation be renamed to GSC2.2N0211313705? Comments from other observers are also welcomed.
