Title: Kinematic Properties of the Northern Arm of the Sagittarius Stream

Abstract: We are requesting time on the WIYN 3.5m with Hydra to extend our study of the tidal tails of the Sagittarius dwarf spheroidal galaxy. At the end of August we successfully observed a section of the Southern Arm and we are now proposing to observe a portion of the Northern Arm. Our goal is to continue our program to explore the ratio of horizontal branch to red clump stars within the stream and to search for variations within this ratio between the trailing and leading arms and over several orbital wraps.
