Figure 1: Projection of the MGS spacecraft trajectory and observed magnetic field onto a plane perpendicular to the Mars-Sun line and the Mars orbit plane for periapsis pass 6, 1997 day 264. The magnetic field is illustrated at 3 s intervals by a scaled vector projection of B originating from the spacecraft position at such times.
