Aur Type Binary 32 Cyg.)

       The High Resolution Spectrograph (Sides One and Two) was used to =
make spectrographic observations of the Zeta Aug class binary system =
HD192909 (aka, 32 Cyg) in order to study its extended envelope.  This =
binary system consists of a B class dwarf star, and a K class supergiant =
that eclipses the dwarf.  A wavelength calibration image was also taken.  =
The observations were executed as scheduled, and no anomalies were noted. =


   1.2 Completed Two Sets of FOS/RD 6914 (FOS Cycle 6: Location of =
Spectra and Wavelength Calibration - Red Side)
