Abstract
THE globular cluster NGC 362 (α1950 = 0lh 01.6m, δ1950 = −71° 07′) is situated about 1° north of the north end of the Bar of the Small Magellanic Cloud (SMC). Its integrated spectral type1, F8, and integrated colours2, B–V = 0.78m and U–B = 0.17m, would indicate that it probably belongs to the group of globular clusters typified by M3 and M5. These clusters have colour magnitude (c–m) diagrams characterized by a horizontal branch with a fairly even distribution of stars across the RR Lyrae gap, and a giant branch which, at (B–V)0 = 1.4m, rises to a height, ΔV, of approximately 2.6m above the horizontal branch3. NGC 362 has seven cluster type variables the mean period of which is 0.542d. This period is also characteristic of the variables in M3-type globular clusters.
