The Delta-Scuti(?)variable, 20 CVn, has been observed photoelectrically on two nights, JD 2446586 and JD 2446949, inU, B andV filters. The average amplitudes on these nights come out to be 0.13 mag and 0.08 mag with the time durations from Maximum to Maximum of 0.035 mag and 0.045 mag, respectively. A period appears to be 0{./d}13. The average spectral type comes out to be F0. The shapes of the light and colour curves are variable. The possibility of it being an eclipsing binary cannot altogether be ruled-out.
