Astronomical sky spectra from the 29–31 October 2003 geomagnetic superstorms: Observations of O+(2Do–4So) and other emissions
High-resolution spectra of the night sky at near-equatorial latitudes have been obtained with the Ultraviolet and Visual Echelle Spectrograph on the 8.2 m Kueyen telescope, European Southern Observatory, Cerro Paranal, Chile, during the 29–31 October 2003 geomagnetic superstorms. These spectra show indications of both thermospheric and ionospheric disturbance. Numerous emission features observed in these spectra have behaviors that correlate with the negative magnitude of the disturbance storm time index (Dst), a measure o ...
