            HR 2707: A DELTA SCUTI VARIABLE


The bright star HR 2707, (V_E, B-V, U-B)=(5.4, +0.29, +0.18) has been found to
be a small amplitude variable. Observations on December 23 and 24, 1967 are
shown in Figure 1; the comparison 

                           [FIGURE 1]

star was HR 2714 (4.^m1, A0).  The period
is uncertain but probably near 0.^d11. The amplitude may be variable as
observations under poorer conditions on December 25 and 26 failed to show a
variation greater than 0.^m02. The radial velocity is variable with a mean
value of +30 km/s, giving (U,V,W)=(+27,-15,-16) if M_V=+0.^m5 and using the
well determined proper motion of (mu_alpha cos delta, mu_delta)= -0."033,
-0."016).
