BDS 1269 is a visual binary system with a Delta Scuti star as the primary (Mechler, 1974) and a normal early F main sequence secondary BDS 1269B (HD 15164). Careful observations concerning the brighter primary in this system BDS 1269A (HD 15165, VW Ari) have been undertaken since its first finding by Mechler in 1974. Besides, an unpublished 8 night observation carried out on a 60cm reflector with a Johnson V filter was also got by Y. Liu and M. Cao in November 1990 at Xinglong observatory. The observing log is presented in Table 1. We divided all these collected different observations according to their time into four data sets (data 1, data 2, data 3 and data 4). However, different periods have been rendered by some of the observers and even adopting quite the same data, discrepant results were reported.
