        NEW DELTA-SCUTI-TYPE VARIABLE IN TRIANGULUM

   While observing the eclipsing binary V Trianguli: 1h28m57s,
+30deg6'27" (1950) a nearby star at 1h29m15s, +30deg7'10" (1950) was
found to be variable. It was observed in the Washington Photometric
System colors C, M, and V on eight different nights from October, 1982
to January, 1983. The amplitude of variation was 0.12mag in C, 0.083mag
in M, and 0.0 7mag in V and was roughly sinusoidal. Data for the two
nights with the best coverage, JD2445341 and JD2445351, are shown in
Figure 1. SAO 54783 was used as a comparison star. Delta magnitude
in V (new variable - SAO 54783) is plotted versus heliocentric Julian
Date.

                            [FIGURE 1]




   Compared to V Tri at maximum light the new variable is 0.3mag fainter
in V, or 11.2mag. Further, it has identical (M-V) and (C-M) indices which
implies the same spectral type, A3, as V Tri. A periodogram analysis
of the data from all nights indicates a period near 0.10 days, with the
possibility of multiple periods. The light amplitude variation, period
and spectral type indicate the new variable is a delta-Scuti-type
variable.
