Description:
The BV photometric investigation of the Southern globular cluster NGC
1904 was carried out using the 1m telescope of Cerro Las Campanas
(CARSO, 2 nights in February 1973 and 2 nights in April 1973),
and the 1m telescope at la Silla (ESO, 4 nights in February 1975).
The identification of the stars was made by B. Skiff (Lowell Obs.)
in October 2010.
