Abstract
1998 UBV photometry of short period eclipsing binary ST Aquarii have been p resented. The photometric solution obtained from light curve analysis by th e method of differential corrections indicates that the system can be class ified as a near contact binary. Derived value for the ratio of radii (k = [ r(h)]/[r(c)] congruent to 0.67) shows that both components cannot be consid ered to be Main-Sequence, but they are probably evolved from M.S.
