Astrometry-The observaton and photography of asteroids and Near Earth Objects (NEOs), for characterization.

Abstract

Astrometry is the measurement of positions in the sky, positions of asteroids, and satellites of the outer planets. We used the Astro Mechanics, Ritchey-Chretien reflecting, 0.6m telescope at Table Mountain Observatory (TMO) located in Wrightwood, CA. Equipped with a 4k CCD camera, (the ProLine4096x4096 imaging array with 9um pixels), using 180 second exposures, we imaged the asteroids and outer satellites. We calculated two to three different positions of the asteroids, with different star fields, to best obtain positions. We obtained many different, accurate positions of asteroids, and the seeing conditions, which were noted and inputted, then calculated by the reduction program. We submitted our data to the Minor Planet Center, which were used by the optical navigation group at Jet Propulsion Laboratory (JPL). The data were also used for predicting occulting events. Through the execution of several Linux reduction programs and scripts, we reduced the data for the most accurate orbital positions.
