Observations of a Quiescent Prominence Straddling the Solar Limb during the Total Eclipse of 11 July 1991

The following instruments viewed a prominence straddling the SW limb during the total eclipse of 11 July 1991: the Normal Incidence X-ray Telescope (NIXT) launched on a NASA sounding rocket at White Sands, New Mexico; a 70 mm cine camera with broad-band red filter at the prime focus of the Canada-France-Hawaii Telescope (CFHT); the NASA/NSO spectromagnetograph at Kitt Peak; and the Hα-scanning photoheliograph at the Ottawa River Solar Observatory (ORSO). Only the CFHT was in the path of totality; the prominence and overlying corona filled the field of view of its 70 mm camera (Koutchmy et al., 1994). The other instruments viewed the entire uneclipsed surface by scanning (NSO, ORSO) or in single exposures (NIXT).
