The Solar Mass Ejection Imager (SMEI) was launched in January 2003 into Earth orbit. SMEI is designed to observe heliospheric structures illuminated by Thomson-scattered sunlight. The design specification for SMEI is 0.1% in differential photometry for bright unresolved objects, to enable star removal from the heliospheric maps. Such a near-Earth imager will also provide photometric time-series measurements of these stars as a by-product of this removal process. For each 101-minute orbit, SMEI will deliver near complete sky maps having an expected (1 sigma) photometric resolution of about the equivalent of an 11th magnitude star in a square degree. We will report on progress in establishing the photometric calibrations for the SMEI cameras, and discuss SMEI's potential for delivering photometric time-series measurements, which data can then be applied to the study of variable stars, eclipsing stellar systems, and to search for extrasolar planets by the occultation method.
