             AN RR LYRAE STAR IN NGC 288




   In August 1975, one of us (MHL) obtained 17 B plates of
the globular cluster NGC 288 on 9 nights with the 1-m Yale 
reflector at Cerro Tololo Inter-American Observatory. Blinking of
10 pairs of plates revealed one new variable star, V2, in 
addition to the long period variable discovered by Oosterhoff (1943).
V2 lies approximately 36" north and 20" east of the center of
the cluster as defined by Oosterhoff. The locations of V1 and
V2 in the cluster are shown in Fig. 1.
   With a sequence from the photometry of Cannon (1974), we
made visual estimates of the B magnitudes of V2 on our plates.
Table 1 lists the heliocentric Julian Dates and magnitudes.
With a period search computer program provided by E.L. Wright,
we determined the period of V2 to be 0.679d with epoch of maximum
J.D.2443011.853d. The corresponding light curve is given in
Fig. 2.
   The mean B magnitude for V2 is about 15.4m. If B-V ~ +0.3m,
E_B-V= 0.0m (Harris, 1976) and V_HB ~ 0.6m, then (m-M)_V ~14.5m, which
is only 0.2m different from Harris's value of 14.70m. Thus it
seems probable that V2 is a member of NGC 288.
