             A NEW BRIGHT SOUTHERN VARIABLE STAR

	The star CPD -67deg3312 = HD 156545 (A0) has been found to be
variable on the Gevaert 67A50 Scientia plates taken by A. Van Hoof,
F. C. Bertiau and the authors during the years 1957-1964. All the
photographic plates have been taken with the 10"-Metcalf telescope of
the Boyden Observatory (South Africa) with an exposure time of 30
minutes.
	We estimated the variable on 320 plates using the five 
comparison stars:
	a:  - 67deg3337		7.8m
	b:  - 68deg2914		8.1
	c:  - 68deg2916		8.5
	d:  - 68deg2921		8.8
	e:  - 67deg3319		9.1

	The estimates proved the star to be of the Algol type. The
period has been derived by least squares from twelve minima:
		P = 2.312923d +/- 0.000033d
	The extreme values are:
		7.88m and 8.97m
	Mean epoch of minimum: JD 2436891.904
	The individual minima (fainter than 8.80m) are:
