HV 1369 (P = 31d) in the southwest part of the SMC appeared to be far too underluminous for its period in a photometric VBLUW study (van Genderen, 1977). VBLUW data, however, seems to support its long period. A comparison with the brightnesses of 10 other Cepheids distributed all over the SMC with similar periods shows that HV 1369 is possibly 32 + or - 7 kpc more distant than the other Cepheids. This fact agrees with the idea of a large depth at the southwest part of the bar up to 23 kpc based on distance differences of optical objects (Florsch, et al. 1981). It also agrees with the possibility that an H I arm exists in that area, extending backwards in the line of sight.
