Aurorae on Mars have previously been observed in ultraviolet from orbit by ESA's Mars Express and NASA's MAVEN missions.
Predicting Martian aurorae is difficult, requiring commands to Perseverance to be scheduled three days in advance.
Aurorae occur when solar wind particles from coronal mass ejections (CMEs) collide with atmospheric molecules, producing light.
Early failures in detecting aurorae were explained by slow CME velocities.
