[3.04] High resolution spectroscopy of active regions with adaptive optic

M. Sigwarth, T.R. Rimmele (National Solar Observatory/AURA Inc.)

With the NSO low-order adaptive optic system at the NSO Dunn Solar Telescope it is now possible to perform spectroscopic measurements at high angular resolution and high signal-to-noise level. The performance of the AO system for spectroscopic investigations will be demonstrated.

By using a dual Fabry-Perot spectrometer we obtained spectral line scans of active regions with a spatial resolution of 0.3 arcsec at 557nm. We use these data to adress questions of magnetoconvection in active regions.
