Abstract
ABSTRACT The proper motions of two 'central' star candidates in S216, LS V + 46 deg 21 and AS 84, were derived from observational data. The observations of S216 were carried out using the 1-meter refractor telescope of the Yerkes Observatory, and astrometric measurements were obtained with a MADRAF PDS microdensitometer. Proper motion measurements of the star 10R - 471 from 1929 were used for comparison. The relative proper motions derived from the comparison were: 2.0-0.8 + or - 0.4 deg per century for LS V + 46 deg 21, and -0.8 + 0.1 + or 0.4 deg per century for AS 84. It is suggested that the proper motion of LS V + 46 deg 21 may be sufficient to warrant its classification as the 'central' star of S216.
