Coordinated observations with high resolution spectrographs (HRTS, SERTS, MSDP)
Abstract
Observations with the High Resolution Telescope Spectrograph (HRTS) aboard Spacelab2 in 1985, and more recently with the Solar Extreme-ultraviolet Rocket Telescope and Spectrometer (SERTS) during the rocket flight of May 5, 1989 were well coordinated with the Meudon instruments, principally with the Multichannel Subtractive Double Pass (MSDP) spectrograph. These instruments allow the study of phenomena in a large temperature range and the determination of the energy budget. MSDP observations coordinated with the SERTS have permitted the analysis of physical parameters of coronal plasma surrounding dynamical chromospheric events, such as preflaring region and a filament. By combining Hα spectrograms and HRTS data, C IV flow (~50 km s-1) detected at the footpoints of a prominence has been interpreted by horizontal velocities along the axis of the arches of the prominence.
