Extreme ultra-violet filtergrams and X-ray spectroscopy of active regions and flares from TRC/XSST rocket campaigns
Abstract
Ultraviolet filtergrams and X ray spectra were taken by the joint LPSP/Lockheed rocket experiment TRC/XSST during four international campaigns involving also ground observations. XSST spectra in the range 8 to 97A were obtained on the 13 July 1982 flare. From the EUV filtergrams obtained by the TRC (Transition Region Camera), we could derive calibrated fluxes in the 220nm and 160 nm continua, in the Ly alpha and C IV lines, spanning a range of temperatures from medium photosphere (5 000K), temperature minimum (4 200K), and transition region (20 000 and 100 000 K). For active regions and a flare, the TRC fluxes are compared to other data and to corresponding calculations from semiempirical models. Finally, the scientific prospects of an advanced TRC/XSST payload onboard future missions are discussed.
