Cloudcroft occulation summary. II - April 1980-December 1981
Lunar occultation observations obtained between April 1980 and December1981 at Cloudcroft Observatory are summarized. 24 of the 75 occulationsreported involve stars brighter than seventh magnitude. Although noangular diameter measurements are included, six observations arepresented which indicate duplicity; three of these stars are known orsuspected binaries, and the others are apparently new discoveries.Occultation observations of the Galilean satellites obtained on 16 July1980 and results from the Hyades passage of 19 September 1981 areincluded.
| Interstellar extinction in the Taurus dark clouds. II
The results of photoelectric photometry of 89 stars in the Vilniusseven-color system in the area of the Taurus dark clouds withcoordinates (1950) 4h16m-4h33m, +16 deg-+20 deg are presented.Photometric spectral types, absolute magnitudes, color excesses,interstellar extinctions and distances of the stars are determined. Thedistance of the dark nebula is found to be 140 pc and is in goodagreement with the distance determined by Straizys and Meistas (1980)for the dark nebula Khavtassi 286, 278. The average extinction in theinvestigated area is of the order of 1.4.
