Includes bibliographical references (pages 23-24). This thesis was designed to make spectroscopic measurements of Ceres within the visible spectrum, specifically within the wavelength range of 6000 and 7000 Angstroms. The asteroid was observed for 6 nights, for lengths of time varying from 3 to 7.5 hours. The main goal was to support/refute the previous findings about absorption features within the wavelength range being observed. Additionally, this thesis was designed to determine the rotational variability of minerals on Ceres. In order to determine the asteroid's variablity, the rotational period of Ceres was divided into eight phases, and average spectra were determined for each phase. The results show that there is a weak rotational variability of the feature between 6200 and 6400 Angstroms. The feature varies over the surface of Ceres by 2.5% with a mean error of 1.6%. There have been previous reports of absorption features on asteroids between 6000 and 6500 Angstroms, which have been associated with ferric Fe absorptions in Fe alteration minerals. Examples of such minerals include goethite and iron oxide hematite. by Phoebe J. Henderson.
