             IRC +10371, A NEW VARIABLE STAR



  Inspection of several low-dispersion, blue-region, objective-prism plates
has revealed an obvious variability of the red star IRC +10371 (alpha=18h40m10s,
delta= +13d58.0' - 1950). The star was relatively bright on plates taken on Aug.
2, 3, and 5, 1970, but substantially fainter (probably 3/4 mag. or more) on
one taken July 21, 1968. A chart for this object is provided by Wyckoff and
Wehinger (1974), who have classified it M6 on a visual-region image-tube
plate. It is no doubt a slowly variable M giant.
