Abstract:
Unpublished uvby-β photoelectric photometry of the open cluster
NGC 6882/5 is presented. Utilizing already tested distance determinations
through photometric techniques, it is found that there are at least
two distinct star accumulations in the direction of the open cluster
NGC 6882/5. A brief discussion is made of the nature of the previously
found short period variables.
Description:
All the observations were carried out at the Observatorio Astromonico
Nacional at San Pedro Martir, Mexico with the 150cm telescope equipped
with a spectrometer, in three seasons: July-August 1986 (four nights),
Jun 1997 (6 nights) and July 2000 (4 nights).
