This log identifies possible pointed observations that were performed with the Y-axis detectors of the SAS-C X-ray observatory of celestial X-ray sources. The log was compiled from notes made at the time of the observations. It is neither a complete nor fully accurate list of all pointed observations, but it can be used as an initial reference for the SAS-C data base. The columns in the log are: the right ascension/declination designation of the source in 1950 coordinates, the common name of the X-ray source or its optical counterpart, the start and end universal dates of the observation, and duration of observation in days. Possible errors in the log are the misclassification of an observation as a pointed observation when it was either a spinning or dither observation, and inaccuracy in the dates of the start and end of an observation. Anyone interested in the listed sources or time periods can obtain further information and data directly from Dr. George Clark, Department of Physics, Bldg. 37-611, Massachusetts Institute of Technology, Cambridge, MA 02139.
