Monthly report for July and August 2002 by Christian A. Hummel: Hummel finished the analysis of Eta Vir and wrote a first draft of a paper on these results. A second and improved version was made in August. Hummel wrote and submitted his manuscript for the proceedings of the SPIE meeting in Hawaii. He also prepared the poster, and his part of the talk by Benson et al. Hummel scheduled and reduced more than 11 nights of NPOI observations. He investigated the feasibility of a "global fringe fitting" algorithm using the raw data of several scans. Hummel attended the SPIE meeting in late August.
