The brightness vertical profile shows a maximum at 600 km above 1 bar, with no apparent difference between the Main Alfv\\'en Wing spot emission and the tail of the footprint. This observation is more compatible with a broadband energy distribution of the precipitating electrons, than a monoenergetic one. The temporal profile of H3+ column density has been observed after the passage of the MAW and shows a hyperbolic decrease.
