ULTRAVIOLET OBSERVATIONS OF A DYNAMIC EVENT IN THE SOLAR CORONA

The Solar Ultraviolet Measurements of Emitted Radiation instrument (SU MER) observations show high Doppler shifts and temporal variations in profiles of ultraviolet lines from low temperature gas in the corona a bove the active region NOAA 7974. The profiles indicate approximate to 100 km s(-1) flows coming from an almost stationary source that appea rs bright in the lines of N III and Si III. The variations in line-of- sight velocities and intensities suggest small knots of cooling plasma emanating from a small region high in the corona. A few are sec sunwa rd of the region where the cool flows are seen is an elongated region of enhanced higher temperature, low velocity Ne VI and Mg VI line emis sion.
