HD 148703

A request for observations by astronomers at the University of Wroclaw in Poland was announced by AAVSO on June 8.

The bright (magnitude 4.23 V) long period eclipsing binary HD 148703 (aka N Sco, HR 6143) is expected to undergo primary and secondary eclipses on June 11 and 14 each lasting around 20 hours.

The brightness and requested precision of 0.01 or better makes this an ideal candidate for wide field DSLR photometry.

I’ve taken pre-eclipse images but cloud prevented me from imaging the primary eclipse. I’ll take further images over the next few days, hoping to record the secondary eclipse.
