Hi Milton,


You certainly chose an oddball asteroid to study.


Since it has such a short rotational period, I might devote a night to it in the next few weeks to see what kind of results I get.  It passes right overhead GMARS and is visible through less than two air masses for about nine hours during November.


If you wanted to put your images in ZIP'd file and put it where I could download it, I'd be happy to run them through MPO Canopus. The big difference between Canopus and AstroIIDC is that it uses five reference stars (not just one), and its databases know the spectral types and variability of all the comp stars.

Hi folks;


I decided to record a 5 hour Light curve for Asteroid Devosa on Wednesday (Nov 10). It's approximately Mag 11.2, has a change of 0.45 to 0.86 mags and rotates once ever 4.56 hours, so it's something one can do in a single longish night (running from 9 pm to 2 am in my case)...
