The SPARTAN 201 Ultraviolet Coronal Spectrometer
Abstract
The Spartan 201 spacecraft, a free-flying autonomous satellite carried into orbit, released, and then recovered by the Space Shuttle, completed its first mission in April 1993. Spartan 201 carries two instruments: a UV Coronagraph (Spartan/UVCS) from the Harvard-Smithsonian Center for Astrophysics and a White Light Coronagraph from Goddard Space Flight Center and the High Altitude Observatory. The optical system of the Spartan/UVCS consists of an externally and internally occulted coronagraph with two telescope mirrors coupled to a dual spectrograph system, one of which makes line profile and intensity measurements near lambda 1216 Angstroms. The other makes intensity measurements of each of the OVI doublet lines at lambda lambda 1032 and 1037 Angstroms. A summary of the observations from the first mission will be presented. We will also describe the Spartan/UVCS instrument and discuss the instrument's characterization and flight performance. Plans for the next mission in September 1994 will be discussed. Supported in part by NASA Grant no. NAG 5-613 to the Smithsonian Astrophysical Observatory.
