        12 NEW VARIABLE STARS IN NGC 6402




   A recently determined color-magnitude diagram for
NGC 6402 (M14)(1) showed a number of stars which were not
known to be variable and which fell in the variable star
gap. Using 11 plates taken with the 61-inch at Flagstaff
in 1967 by Dr. Serge Demers as well as 5 plates taken with
the Mt. Wilson 100-inch by Dr. H. Arp in 1952, the authors
checked these stars for variability, In this way 11 new
variables have been found. In addition, another was found
by chance.
   In the table below, the coordinates x and y were measured 
using the system of reference originally used by Helen
Sawyer (2). The B magnitudes were determined using standards
given in Demers and Wehlau (3).
