Use GSC name if the object is not TY Sge itself.< Yes, and my identification of TY Sge should be made clear also. TY SGE = GSC 1621:53 GSC2.2 N0211313705 20:03:37.47 +17:01:28.5 V=12.011+/-0.014 B-V=1.964+/-0.010 (from A. Henden dat file) Apparently a SR type variable with a range of 11.7-12.2V and a period of around 99 days. This star was historically used as a comp star on the RZ Sge charts, either a 119 or 120 depending on which chart you used. The star previously marked as TY Sge on older versions of the AAVSO charts is now temporarily designated "var" in the unwieldy AAVSO system of identification of secondary variables on charts. So SGEVAR is- GSC2.2 N021131332556 20:03:36.61 +17:01:13.0 V=13.712+/-0.022 B-V=0.634+/-0.022 (from A. Henden dat file) Both stars are in the immediate vicinity of RZ Sge, whose AAVSO charts have been the subject of quite a bit of work recently by both the aavso-sequence and aavso-chart teams.
