Abstract

(Abstract only) Rapid cadence (every 42 seconds) photometry of ε Aur in September 2009, using a V-filtered 50 mm f/2.8 camera lens and an SBIG ST-7E camera, does not show short period brightness variations significantly different from those of the comparison star η Aurigae. On a scale of minutes to hours, the only variations detected are attributable to scintillation and differences in atmospheric extinction.
