An improved limit on the flux of magnetic monopoles in the vicinity of the solar system is obtained, assuming that monopoles strongly catalyze nucleon decay (the Rubakov-Callan effect). Flux limits are presented for monopole velocities from 10{sup {minus}5}{ital c} to 10{sup {minus}1}{ital c} and for monopole-nucleon cross sections between 10{sup {minus}27} cm{sup 2} and 10{sup {minus}21} cm{sup 2}. For a representative velocity {beta}{approx}10{sup {minus}3}, and cross section {sigma}{approx}10{sup {minus}24} cm{sup 2}, we obtain a limit {ital F}{sub {ital m}}{lt}2.7{times}10{sup {minus}15} cm{sup {minus}2} sr{minus}1 sec {sup {minus}1} and for {sigma}{approx}10{sup {minus}25} cm{sup 2}, {ital F}{sub {ital m}}{lt}1.0{times}10{sup {minus}15} cm{sup {minus}2}sr{sup {minus}1}sec{sup {minus}1} at 90% C.L.
