Scientific paper

BVRI photometric observations of AD Leo and Gl 490A, obtained using a two-star photometer on the 24-inch telescope at Table Mountain Observatory during March-April 1981 are reported. V and R light curves are presented for each star, and the periods and m(v) amplitudes of the variations are given as 2.7 + or - 0.05 d and 0.024 + or - 0.002 mag for AD Leo and 3.3 + or - 0.05 d and 0.072 + or - 0.002 mag for Gl 490A.
