The Behlen observatory 0.76 m telescope CCD photometer has been used to obtain nearly 700 observations of the short period eclipsing binary V508 Cyg. These observations were done using V and R bandpass filters on 9 nights in 1992. Previously published light elements and the present eight determinations of eclipse timings are used to determine a new epoch and a more accurate orbital period of 0.7796587 days. The photometric observations and solutions which have been obtained with the 1993 version of the Wilson- Devinney model show that V508 Cyg is a W UMa type contact binary system. Analyses give two …

Far-Ultraviolet Stellar Photometry: Fields In Sagittarius And Scorpius, Edward G. Schmidt, George R. Carruthers

Far-ultraviolet photometry for 741 objects in a field in Sagittarius centered near M8 and 54 1 objects in a field centered near ζ Scorpii is presented. These data were extracted from electrographic images obtained with two cameras during a shuttle flight in 1991 April/May. The cameras provided band passes with λeff= 1375 Å and λeff= 1781 Å. Synthetic colors show that these bands are sensitive to effective temperature for hot stars. Our measurements were placed on a quantitative far-ultraviolet magnitude scale by convolving the spectra of stars observed by IUE with our cameras' spectral response functions. …
