Abstract
HR 2989 is a 8 Scuti star with a period of 0d09526 and amplitudes in V, B, and U of 0"'055, , and , respectively. In each color the light variations are in phase, nearly sinusoidal, and constant in amplitude. The period is consistent with those of other 8 Scuti stars of similar absolute magnitude (+ 1.4) and color index ((b-y) = 0.112). Key words: variable stars - photometry - 8 Scuti variable
