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

Well done, David.
Another notch in your belt! :thumbsup:

You will be needing a longer belt soon David :clap: Congratulation. :2thumbs:

Amazing! must be a pretty cool feeling when you have the eureka moment, and aha! got something, great work!

[higginsdj]

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.

Nice work David, a Classic catch. :)
