                   VARIABILITY OF NSV 01715


   In measuring InT stars, DR and DQ Tauri, I noticed fairly big variability 
of a nearby star which was listed as NSV 01715. More than 350
photographs of this field were taken since 1980 with 18cm and 25cm Schmidt
cameras. Tri-X film was used with the yellow-green filter which gives
the brightness very close to visual magnitude.


                           [FIGURE 1]

          Figure 1. Recent variation of NSV 01715.


   The results in recent years are shown in Figure 1. It is noticeable
that the star often shows very rapid variation, more than one magnitude in
a few days, being more active than DQ Tauri recently. The range was
13.0-14.6v so far.
   The star was noticed by G. Haro, B. Iriarte and E. Chavira (1953) to
have very strong H-alpha emission, and was suggested to be an In variable. DR
and DQ Tauri were found to be variable by P.N. Kholopov in 1951, but not
this star. These facts make me imagine that the star was not so active
in around 1951.
