Photoelectric circular polarization measurements have been obtained fo
r the A2pSrEu star HD 115708. These data indicate the presence of an a
pproximately dipolar magnetic field whose line-of-sight component vari
es sinusoidally with extrema of -1.5 and +0.9 kG. The period of this v
ariation is found to be 5(d).07622 +/- 0(d).0004. The inclination of t
he rotation axis to the line-of-sight and the magnetic axis obliquity
have been calculated employing the method of Leroy et al. (1995). Thes
e values are i = 130 degrees +/- 15 degrees and beta = 77 degrees +/-
6 degrees respectively.
