  IMPROVED ELEMENTS OF THE NEW ECLIPSING BINARY BD +60d2289


In IAU I.B.V.S. No. 980 (1975) F. Gieseking announced BD+60d2289
(9.3m) to be an eclipsing variable of the EB-type and published
the following preliminary elements:

             Min._hel = JD 2441130.51 + 2.10438d   E
                                  +-1       +-2

The plate archive of the Lippert-Astrograph contains about 150
plates taken with the Triplet K(300/1500) for faint variables in
this Cepheus field. Though the exposure time,of 30 minutes is 
relatively long for such a bright star - limit magnitude about 17m-
excluding Iris-photometer measurements, estimations by Pickering's
method fix one pronounced minimum (4 plates in one night) and 5
near-minimum dates (1 or 2 plates). They are shown in the following 
table adding 6 near-minimum values of Gieseking.

A weighted least-square solution yields the following improved
elements:

             Min._hel = JD 2431029.318 + 2.1044173d   E
                                   +-8        +-26

This relatively bright BD variable recommends itself for further
photoelectric observation.
