The globular cluster NGC 288.

A BV photometric investigation of the Globular Cluster NGC 288 situated in the direction of the South Galactic Pole, was carried out using the lm telescope of Cerro La Silla (ESO) for the photoelectric work and the 1m telescope of Cerro Las Campanas (CARSO) for the photographic work. Sixteen stars were observed photoelectrically, the limiting magnitude is V= 15.98. Using this sequence 280 stars were measured photographically. The derived apparent distance modulus is (m - M) app. = 14W80. The reddening E(B - V) = . The true distance modulus is (m- M) = 14.65. The distance is 8.5 kpc from the sun and the galactic plane and 12 kpe from the galactic centre. The main feature of the colour magnitude diagram is the presence of a large sample of blue horizontal branch stars in the range -0.23 <(B - V) <0.03. Due to the undefined position of the horizontal branch it is difficult to determine its metallicity from the AV method; but the average steepness of the giant branch suggests that this cluster ranks among those of medium metallicity richness. Key words: Globular Cluster - BV photometry - horizontal branch
