AB: The NASA Cusp rocket Campaign of December 2002 provides a unique combination of in situ and ground-based instrumentation for the investigation of the Earth's cusp. The CUTLASS HF radars provided 2-D convection measurements over the rocket trajectory region during launch from Ny Alesund on December 14. The radars ran in a special mode with high spatial and temporal resolution. Stereo operations allowed a full 16 beam scan to be generated every 48 s, whilst simultaneously a restricted 6 beam scan localized over the trajectory was generated every 18 s. Excellent data coverage was obtained from both radars over almost the entire rocket trajectory, allowing 2-D convection information to be recovered. The remaining SuperDARN array provided the global convection solution at a resolution of 2 min. The spatial and temporal variations of the ionospheric convection flows under the influence of transient magnetopause reconnection processes will be presented, along with an examination of the location and motion of geophysical boundaries derived from radar spectral width.
