[vsnet-ecl 200] EF Orionis

The GCVS list EF Ori = AN 138.1938 = GSC 738.1561 as an Algol-type eclipsing
binary with the elements of

Min I := (HJD) 2425247,54 + 3,7012 * E.

New lightelectric times of minimum light observed by german and czech
amateurs does not confirm the period of the GCVS. New elements have been
computed to

Min I := (HJD) 2451568,394 (5) + 1,619438 (8) * E.

A period twice the value given above of 3,238876 days is also possible.
