NSO/SP Awarded Subcontract for SWATH Coronagraph (1Sep93)
(from NSO, NOAO Newsletter No. 35, 1 September 1993)

NSO has been subcontracted by the Smithsonian Astrophysical
Observatory, Center for Astrophysics, to build the structure and
optical components of an externally-occulted mirror coronagraph to be
included as one of three instruments on the USAF-funded Space Weather
and Terrestrial Hazards (SWATH) mission. The other two instruments are
short wavelength (63 A and 190 A ) normal-incidence imagers. All
instruments will use 2048-2 CCDs. Leon Golub is the PI for SAO, and Ray
Smartt is the PI on the subcontracted NSO coronagraph effort. Funds for
SWATH are being provided by the Ballistic Missile Defense Organization
through PL/SX at Hanscom AFB; members of the Phillips Lab Solar
Research Branch at Sacramento Peak are included on the SWATH science
team and will further act in the management of the coronagraph program.
SWATH objectives include simultaneous imaging of outer and inner
coronal structure and evolution, detection and studies of coronal mass
ejections and flares, and an attempt to monitor space debris in size
ranges not observable by ground-based telescopes.
