Geostorm is a mission concept to monitor the solar wind for disturbances that lead to geomagnetic storms before they reach Earth. Spacecraft without solar sails, like NASA's Advanced Composition Explorer, provide ~30-60 minutes of warning by orbiting the Sun-Earth L1 Lagrange point. Solar sails would move this point closer to the Sun by counteracting solar gravity with sail thrust, possibly providing 1-2 hours warning. <bibref>West:2000</bibref> <bibref>Yen:2004</bibref> <bibref>West:2004</bibref> <bibref>Young:2007</bibref>
