  The Solar Mass Ejection Imager (SMEI) views nearly every point on the sky
once every 102 minutes and can detect point sources as faint as R~10th
magnitude. Therefore, SMEI can detect or provide upper limits for the optical
afterglow from gamma-ray bursts in the tens of minutes after the burst when
different shocked regions may emit optically. Here we provide upper limits for
58 bursts between 2003 February and 2005 April.
