Title: Photometric observations of the brightest Jupiter Greeks.

Abstract: We propose to make $BVRI$ photometric observations of at least the 113 brightest Jupiter Trojans from both the L4 (Greek) and the L5 (Trojan) Lagrange points using the CTIO 0.9m, in conjunction with data gathered at Lowell Observatory. With these data we hope to reveal any color trends and/or differences between the largest members of the two camps. A comprehensive database of uniform photometry does not exist for this effectively complete sample, so robust comparisons are virtually impossible at this time. These data will also enable comparisons between the Greek and Trojan swarms and other Solar System populations to discover the possible origins of the two camps, which remain surprisingly obscure. In non-photometric conditions, we will measure light curves that yield information about albedo and color changes, shapes, and rotation periods. Here we propose for a final southern run to complete our Greek L4 sample. emph{The proposed observations will comprise a significant portion of the PI's PhD thesis.}
