V844 Her in Superoutburst

[coatesg]

Currently in superoutburst (max light 16th April), V844 Her is an SU UMa type Cataclysmic Variable, and is displaying superhumps in the light curve with an amplitude of about 0.16mag.

Captured from W Oxon, 151 x 90s, 350mm newt, ST2000XM, V filter (most of it after I nodded off on the sofa - luckily it is well placed to stay in the "slot" of the dome for almost all the session...)

Those are wonderful superhumps Graeme!

Cheers! (More by luck after I nodded off, but probably got more data than I otherwise would have done 😆)

All the  best data gathering is done while asleep in my view. Stops you biasing the results!
