Abstract
We report the results of the first direct search for grand-unified-theory magnetic monopoles with adequate sensitivity to detect a flux as small as the Parker flux limit. If stable monopole-nucleus bound states exist then the observed absence of monopole tracks in our 4.6×-yr-old mica detector places an upper limit of to on the flux of grand-unified-theory monopoles having velocity to .
