Abstract

 

Visual estimates are presented that show ¹ PsA to have a semiregular light curve with an average amplitude of 0.7 magnitude and a period of approximately 8.625 days.  These results are in contrast to the available literature, that either calls ¹ PsA a small-amplitude Cepheid or states that the star was not variable in 1964 and 1970.  Spectra and absolute magnitude indicate that the star lies outside the instability strip.
