               ELEMENTS FOR IQ PERSEI


The GCVS II (1970) gives no elements for this probable Algol-type variable, only
the time for one minimum is published. Observations of AV-members lead to the
following elements:

Min I = JD 2433546.5036+1.7435637d * E.

The following minima were available for the calculations:

  230.389               W. Bischof   15    +-0.000
  244.338:              W. Bischof   15     +0.001:
  249.567               W. Bischof   18    +-0.000

n is the number of the individual estimates used for timing the respective
minimum, : means that the time of minimum is uncertain. Only the 4 accurate
minima were used to calculate the above elements.

Type of variability is Algol. The visual observations did not lead to a
secondary minimum of observable depth. The "D" of primary minimum is 0.2d, the
"d" may be 0.0h to 1.0h. The visual amplitude is about 0.6m-0.7m. A
complete description of the observations with lightcurve shall be published in
AV-Rundbrief no. 3/1972.
