The following star is less than 1.2" from the reported position of this transient: GALEX J201005.0+130300 (NUV= 16.97 mag) = USNO-B1.0 1030-0638093 (R1= 15.86, B2= 16.82, R2= 16.16, I= 16.62 mag) = GSC2.3 N1UX000016 (F= 15.37, j= 16.96, V= 14.73, N= 15.79 mag) = 2MASS J20100514+1303006 (J= 15.936, H= 15.530, K= 15.230 mag) = WISE J201005.15+130300.9 (W1= 14.224, W2= 14.155, W3= 12.576 mag). The Gaia DR1 position (RA, DEC at epoch 2015.0, equinox J2000.0) of this star (G= 17.969 mag) is 20h10m05.169s, +13┬░03'00.50".
