                    PHOTOMETRIC LIGHT-CURVE
                 OF BV 417 = HD 126 037 (G 5)


      In Number 47 of the Information Bulletin on Variable Stars of
Commission 27 of the I.A.U., W. STROHMEIER reported the Cepheid
BV 417 to have a period of 7d.1. Ample new plate material from the
Bamberg South-African Station now allowed a complete light-curve (see
figure) and a more accurate period to be derived. The elements of
BV 417 are:

          Max = JD 243 8195.2 + 7d.073 . E

      BV 417 is a Cepheid of type Cdelta with an amplitude of 0m.5.
In deriving the light-curve the following comparison-stars have been
used:

HD 129 041 (A_2) 7m.40 (same value in the Harvard and Cape catalogues)
HD 128 215 (A_3) 7m.85 (mean value of Harvard and Cape)

Individual maxima (brighter than 7m.60)
