Uncertain identification. ASAS-SN magnitudes are for the blend of Gaia DR3 2002737791233858304 (V= 15.9, chosen as the variable star), Gaia DR3 2002737786935134208 (V= 16.2; 0.9" to the S) and Gaia DR3 2002737791224539136 (V= 17.3, 1.9" to the SW). Combined range given. Not an SR as stated in the GCVS (version Nov. 2023). The blended V amplitude (0.42 mag.) is larger than the g amplitude (0.33 mag.), which is typical of reflection (R) variables, but the high luminosity and long period do not support that. |
