New Asteroid Moon

Got another one - found the signature of a moon orbiting a Main Belt Asteroid (though no CBET just yet) - that takes my tally to 7 in the last 18 months.

This one is my favourite as I am the only observer this time and I performed my own detection and analysis. The Pros have calculated P_Primary (Spin axis rotation) is 2.7093hrs and P_Orbit (Orbit period of the moon) is 15.88hrs. My analysis of P_Primary was spot on but my P_Orbit calculation was 0.31% off (most likely since I didn't remove any bad data points - but my process doesn't give me that option).

Still waiting to hear confirmation of sufficient coverage to warrant the submission of a CBET. As soon as the CBET is released I'll have a paper ready to publish on the methodology (will be available on my web site).

Cheers
