Description:
Photoelectric UBV observations were made in two associations in the
Large Magellanic Cloud, in the magnitude range 10.6 to 16.2. The
observations were made at the Cerro Tololo Inter-American Observatory
with the 36-inch telescope in the nights of 1-5 December 1967.
The positions were computed by B. Skiff (Lowell Obs.) in 2009.
