  We present the results of an analysis of 21 spectra of alpha UMi (Polaris)
obtained in September - December 2015. Frequency analysis shows an increase of
the pulsation period up to 8.6 min in comparison to the 2007 observational set.
The radial velocity amplitude comes to 4.16 km s^-1, and it approximately twice
the one found in 2007. The average Teff = 6017 K, and it is close to the value
determined for the 2001-2004 set. Therefore Polaris moves to the red edge of
the Cepheid instability strip (CIS)
