The AFRL SMEI camera on the Coriolis spacecraft takes a 1000x1000 optical picture of 80% of the sky every 102 minutes. Built primarily to track solar coronal mass ejections, it was also envisaged that the data would have other uses. This unique dataset of continuous monitoring of the entire sky has been used to study variations in the brightnesses of stars. A new reduction and analysis method has been used to study the cepheid star Polaris, to take part in the discovery and study of the eclipsing binary nature of the bright star Psi Cen, and to initiate a search for extrasolar planets by the transit method.
