Lyman-alpha rocket spectra and models of the quiet and active solar chromosphere based on partial redistribution diagnostic

We present Lα line profiles obtained with 0''.8 spatial resolution and 50 mA spectral resolution during the first rocket flight of the NRL High Resolution Telescope and Spectrograph (HRTS) instrument. Absolute intensity Lα profiles were obtained for network and cell regions in the quiet Sun, umbral and penumbral regions of a sunspot, two plages and a quiescent prominence off the limb.We propose a new mean quiet Sun chromosphere model consistent with the observed Lα integrated intensity, the LYman continuum slope, and the millimeter continuum. Our model predicts Lyman continuum and Ca II intensities somewhat lower than observed and Mg II intensities a factor of 2 lower than obseved. We also present preliminary models to match representative Lα profiles for bright and dark points in the quiet Sun and bright regions in plages. The plage and bright points models predict negative contrast in Hα at Δlambda> or =0.43 A and 0.22 A, respectively, consistent with observations
