摘要

In 2005-2014 we acquired a total of 135, 137 and 134 measurements in B-, V -and I-c-filters, respectively, for the 5-days Cepheid ASAS 160125-5150.3. Our observations showed variations of light amplitude, which allowed us to suspect the presence of the Blazhko effect. Combining our measurements with ASAS-3 data allowed us to determine the period of the Blazhko effect P-Bl = 1242(d) +/- 10(d), and now ASAS 160125-5150.3 is the second Galactic Cepheid (after V473 Lyr) with strong Blazhko effect pulsating in the first overtone.
