Description:
Photoelectric UBV observations were made with the ESO 1m telescope and
the ESO photometer on 6 nights between 1970-04-01 and 1970-05-03. The
observations were centered around (B1950)13:24-62:23
The positions and identifications of the 3 sequences were computed by
B. Skiff (Lowell Obs.) in September 2010, from a comparison of the
published charts with the computer screen-plots of UCAC2.
