Thanks guys.
Doing some more math I get Dprim = 6.7km with Dsec = 1.6km and a = 11km (Semi Major Axis) but this is based on assumed absolute magnitude. I'll have to do some colour photometry to work out the actual absolute magnitude to constrain the sizes better. The eclipsing events last approx 1.5hrs.
This is one of our smaller MB binaries finds (smallest is around Dprim = 3km).
Cheers
