BD +0 2902
Mr. H. Povenmire, Titusville, Florida, writes: "Reduction of
the grazing occultations of 1968 July 30 and November 16 of BD
+0 2902 (= S.A.O. 138613 = U.S.N.O. Z11685) shows that the star is
almost certainly a previously imdetected binary, the primary being
of magnitude about 7.8 and the secondary about 8.4. The spectral
class of the secondary is thought to be about F2, or very similar
to that of the primary. The separation of the components is estimated
to be only slightly under 1".0, so that it should be fairly
easy to confirm with any large instrument; the position angle of
the secondary seems to be approximtely 208o. In addition, it was
estimated that the primary is approximately 2".8 north of the position
derived from the Yale zone catalogue: some of the error may be
due to the fact that the star is double and to uncertainty in the
position of the moon. The first graze was observed by W. Sander
and myself near Monterey, Ohio, the second by M. Seslar and myself
near Indian Town, Florida."
