We report the rotation rates of the 8 main-belt asteroids 205 Martha, 252 Clementina, 506 Marion, 567 Eleutheria, 613 Ginevra, 869 Mellena, 996 Hilaritas, and 1490 Limpopo and discuss future work. These bodies include one P and seven C-class asteroids located at heliocentric distances of 2.3 to 3.6 AU. Seven of the light curves produced useful results; three of the periods are reported here for the first time, one expands on a previous publication, and the remaining three periods support previously published results. The study of main belt asteroids is an important topic because they can give us insight into planet formation and evolution. The focus of this paper is to use photometry to learn rotation periods. Future work will focus on using this information to obtain shape and pole orientation. Knowing the rotation rate, shape and orientation and their dynamics can place constraints on the early solar system. This project was funded by the National Science Foundation Research Experiences for Undergraduates (REU) program through grant NSF AST-1004872.
