Monthly report for June 2003 by Christian A. Hummel:

Hummel worked on new orbital solutions for the T Tauri system
and plots for a paper on this star.

Hummel co-hosted Dr. Markus Wittkowski (ESO) at USNO, with whom
he worked on coherent integration of NPOI data of Gamma Sagittae.

Hummel reduced some archival data on Altair taken with the W7 station
and fitted a model of a rotating star computed by D. Peterson to
the data.
