Star Name: NSV 285, BV 1643, GSC 5849.1010, NSVS 14686725, ASAS 004506-1854.2 Coordinates (J2000): 00 45 06.11, -18 54 15.4 Variability type: RRAB;   Limits, System: 12.4 - 13.5 (R), 11.9 - 13.2 (V);     Period: 0.497032 d;   Epoch(max): JD 2452569.644

Remarks:

In the ASAS-3 catalog, NSV 285 is erroneously classified as a fundamental-mode Cepheid with a period unusually long for our Galaxy (106.1 d). Actually, from both ROTSE-I and ASAS-3 data, this is an RRAB star with the above elements. M-m = 0.1P.
