HR 7671: Another UU Herculis Star?

Photometry in an eight-filter system was carried out for HR 7671 to determine the nature of this F giant or supergiant. It has been verified that HR 7671 is variable, with a visual amplitude of about 0.3, but, while periods of 28.4 and 11.8 days seem present, these are inadequate to account completely for the variability and would be difficult to interpret astrophysically. The question of whether or not HR 7671 should be considered a UU Her star remains open. Its early F spectral type but later F colors, low gravity, and curious period behavior are reminiscent of UU Her stars, but it seems to be of significantly different chemical composition, and the principal periods are much shorter than found among UU Her stars. High-dispersion spectroscopy, radial velocities, and further photometry of this unusual but bright star, readily accessible from both hemispheres, are most desirable.
