Monthly Reports — 2004 March
 
Murison continued working on the adaptive optics (AO) front end for the FTS project. The new video camera arrived, and Murison constructed a light-tight box so that testing can be done now in the daytime. Murison changed the orientation of the partially reflective pellicle; now the direct starlight path is isolated. Murison subsequently added a neutral density filter in the starlight path to even out the intensity of the direct and indirect images. The starlight image on the fiber (indirect image) and the direct starlight image now appear simultaneously on the guide camera CCD, thus validating the core design element of the AO idea. Murison also made further improvements to AESOP during the course of ray tracing the AO optical design.

Murison and Efroimsky continued work on their joint projects on the dynamical stability of bodies orbiting oblate, precessing planets. Murison concentrated mainly on implementing a planetary ring and satellite module in his numerical program that explores the consequences of Efroimsky's discovery of gauge transformation in celestial mechanics.

Murison and his student Andrei Munteanu continued work on discovering a coordinate geometry that might simplify the orbit-orbit distance problem.

Murison wrote a set of PHP programs to automatically calculate sun rise, set, twilight, and transit times for use on his and the FTS homepages. The times from the PHP programs match exactly the times produced by the AA Department rise/set pages.

Murison again spent considerable time in his duties as Secretary of the AAS Division on Dynamical Astronomy.
