Title Measurements of Zodiacal-light brightness from the Solar Mass Ejection Imager (SMEI)
Abstract Observations from the Solar Mass Ejection Imager (SMEI), now spanning over 6 years, provide unprecedented near-full-sky photometric maps each 102-minute orbit, using data from 3 unfiltered CCD cameras. SMEI\rsquos 0.1\% photometric precision enables observation of heliospheric structures with surface brightness down to several S10\rsquos (an S10 is the equivalent brightness of a 10th magnitude star spread over one square degree). When individual bright stars and an empirical residual sidereal background are removed from the maps, the residue is dominated by the zodiacal light (ZL). The present work combines individual SMEI sky maps to produce daily average maps, and uses the sequence of these for both an empirical characterization of the ZL and an investigation of its variation over time scales from several days to several years.
