Optical observations of the first geodetic satellite ANNA have been made since shortly after launch of the satellite. After 27 months, active observations are still being made. This report contains all of the reducible optical observations made between 9 November 1962 and 20 January 1964 by the USAF, USC and GS, USNO and NASA. In addition, the SAO Baker-Nunn active and passive observations made during November and December 1962 are listed. Brief descriptions of the satellite, the optical beacon, and some of the problems that have arisen during data reduction are presented. Some recommended changes to optical system and data reduction procedures are included. Author
