Lightcurve results for USNO 820-0342790.
USNO 820-0342790 is a 16.3 magnitude star in the constellation Libra, that I discovered it to be variable on images taken on 30 March, 2014.
The variable appears to be a W UMa eclipsing variable with a possible period of around 8 - 10 hours and an amplitude of about 0.4 magnitude. However more observations are required to confirm this since observations were only obtained on 2 nights.
