HadV62 = V1901 Sgr? By comparing the CCD image and Hoffleit's IBVS 1349, it seems more likely than ever that Hoffleit's chart is distorted and HadV62 is identified with V1901 Sgr. This may explain the lack of bright red star at the supposed V1901 Sgr position (from Hoffleit's chart) and the red appearance of HadV62. I hope someone could check the discovery material of V1901 Sgr. Regards, Taichi Kato
