\centerline{\ft GSC\,4540\_1553 IS A NEW BINARY STAR}

\vskip 8mm

\begintext

 CCD images taken at the Bohyunsan Optical Astronomy Observatory (BOAO) with the  1.8-m telescope and
at the Kyung Hee Astronomy Observatory (KHAO) with the 0.76-m telescope on Jan. 21-Mar. 5, 1997 show that the star GSC\,4540\_1553 (V=15.22), located at R.A.=08$^{\rm h}$11\fmm 42\fss 66, Decl.=+76\degr 04\farcmm 53\farcs 22  (equinox 2000.0) varies in magnitude.
From the preliminary analysis of the light curve, I derive the period of 1.1799 day with 0.52 mag (in R) variation in primary and 0.45 mag (in R) variation in secondary minimum using GSC\,4540\_2581 and GSC\,4540\_1931 as the comparisons.
It is considered as an Algol type eclipsing binary star.
The light curve shown is the combined data of Jan. 21-22, 24, 1997 and Feb. 1, 1997 using GSC\,4540\_2581 as a comparison. The average B$-$V colour index of 
this new variable is 0\fm 03 out of minima.
