New red variable stars in two fields in Cepheus and Cygnus.
Abstract
The detection of 15 probably long period variables is reported. The plates are in the r system, the fields being centered at alpha(1950) equals 21h 24m, delta(1950) equals +57deg 15 arcmin (Field I), and alpha(1950) equals 21h 51m, delta(1950) equals +50 deg 50 arcmin (Field II); the field diameter is 4.8 deg. The observed light variations in the r system are given.
