National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Asteroid Orbit Determination and Rotational Period Calculations with CCD Astronomy.

ADA356383

Publication Date	1998
Personal Author	Burtz, D. C.
Page Count	119
Abstract	This paper presents data collected and analyzed relating to photometry and astrometry of asteroids. The photometry involves determining the rotational period of asteroid 583 Klotilde. Astrometry was performed on asteroid 1035 Amata and the calculated position was used to determine its orbital elements. Klotilde was selected for rotational period determination based on its relatively low magnitude, favorable viewing position, and no previous rotational period information. Two hundred six images of Klotilde were taken and analyzed over four viewing nights. Using NASA's IRAF software, the magnitudes of Kiotilde and several comparison stars were determined. Using an Excel spreadsheet, differential photometry was performed and the light curve was plotted. The four nights of data gave a 9.210 +/- 0.005 hour synodic period with an amplitude of 0.18 magnitudes. Thirty-two images of Amata were taken on six different viewing nights. The images were taken with an ST-8 CCD attached to a 41-cm Cassegrain telescope. The data was reduced with the Astrometrica software package, which calculated the right ascension (RA), declination (Dec), and magnitude of Amata using several comparison stars. The computed RA and Dec, along with the times of observation were then used to determine the orbital elements of the asteroid.
