BS UMa - EA type Eclipsing Binary

[coatesg]

Managed to find a well timed minima of BS UMa to capture last night. This is catalogued as an EA type eclipsing binary with period 8.388237hrs, with almost exactly a 1hr rise/fall time. Looks like there's possibly some reflection effect from the "shoulders" in the curves.

Minima timed as HJD 2458940.4271 +/- 0.0001 (calculated using Minima27).

All images 30sec, V filter, ST2000XM, 350mm Newtonian.
