Tikhonov (2019), using the HST images and the TRGB method, places Cas I at D = 1.6+-0.1 Mpc. Besides, he estimates the stellar metallicity of Cas I at the level of z ~ 0.0004 (Z ~ Zo/50). Such a nearby extremely low-metallicity dwarf, if real, would be a very valuable object for detailed studies. An alternative TRGB distance of Cas I, of 4.5+-0.2 Mpc, based on the deeper HST images, was presented in the EDD. It places Cas I midway between IC342 (D ~ 3.3 Mpc) and Maffei 1 (D ~ 5.7 Mpc).
