Instrumental improvements responsible for a factor of 25 increase in the sensitivity of the Fabry‐Perot interferometer enable us to observe for the first time the short wavelength depletion of the Balmer α spectral profile due to hydrogen escape. These results are shown to be consistent with the implications of OGO‐5 observations by Bertaux.
