HST AND GROUND-BASED SIMULTANEOUS OBSERVATIONS

Have time on any optical spectrographs or CCDs?
Please consider joining our efforts for getting simultaneous UV - Ground-based data!

Our goal is to determine UV - optical (Ca II HK, H alpha, and broadband photometric) correlations and variations as a function of stellar age. This will be a critical component in determining UV fluxes between the time when HST is no longer sensitive to the UV and the first light of a future UV mission.
