 AW Cet has been observed during 23 nights. The GCVS does not list elements of this variable star and the ones in the AAVSO VSX database are based on the ASAS automatic survey. The present observing campaign was intended to verify the given elements and check the classification of this star as the available data prior to this study have been of low quality. A list of times of new maxima, the form of the light curve and results for a determination of period and epoch are given. In comparison to the dataset of ASAS and a single maximum of ROTSE we found improved elements. For AW Cet a period of P = 0.3376 ± 0.0010 [d] with the epoch E0 = HJD 2455829.6963 ± 0.0056 and an amplitude of the light variation over a single period of ∆,,m = 0.45 ± 0.05 mag has been found. The type of the star is RRc, but it also shows further variation of its maximum light as well as the time of maximum, which points to the possibility of a Blazhko effect. The database is still not dense enough to determine the Blazhko period which seems to be in the order of 20d. In the same field as AW Cet the star HMB22 = USNO-B1.0 0825-00672447 = VSX J025426.9-003400 has been found as a new variable star of type EA.

Simbad object(s): AW Cet, USNO-B1.0 0825-00672447,
