ocr: UVCS In May 1997, UVCS observed Comet SOHO-8/Slezelberger; in one of the first high-resolution UV - spectroscopic measuremens ev- er made of a comet. The size of the coma at several different posi- tions was measured in HIL Lyman alpha. nage - Anage2 age? 4 CME Ultraviolet Spectra vS. time and space UVCS has measured coronal plasma oaramerers (at large coronal radii) in several CMES in.1996 and 1997. UVCS can isolate spectral lines from both hot (coronal) and cool (chromo- spheric) material, and measure intensities, Doppler shifts, and line shapes. Observed "knots" of emission ore strongly Dop ...
