The evidence indicates that an astronaut carrying out extra-vehicular activity (EVA) in the Shuttle wake in polar orbit could have his EVA equipment charge up to significant voltages if an intense aurora is encountered. Arc discharges are expected to occur that are similar to those that have caused system upsets and failures in geosynchronous orbits. The possibility of hazard to the astronauts must be evaluated quickly, since polar orbit Shuttle launches will soon begin.
