CBET 824 (2478) Tokai

I have uncovered another binary asteroid - this time a synchronous binary where the main body and moon are reasonably close in size (not less than 0.75 the size).

Unlike asynchronous binaries, the ligthcurve on this one is distinctive - looks exacly like the lightcurve of an eclipsing binary star - so I was able to pick it from my first nights worth of data. 3 Professional and 3 additional amateur observatories (Europe, Australia and the US) jumped in to assist with observations to resolve the rotational and orbital periods quickly.

Cheers

Yes, it was a great feeling as it was the first target I could categorically identify as a binary all by myself - the pros called it a Classic example.
