Abstract

We explore the feasibility of adaptive optics for observations of prominences off the solar limb. We installed a wavefront sensor prototype on the GST at the Big Bear Solar Observatory. This sensor is used to conduct open and closed loop experiments to characterize the limitations of this application following up on first demonstrations at the DST. The sensor will enable us to optimize parameters and algorithms for a potential future implementation on NSF's Daniel K. Inouye Solar Telescope. Unlike the granular structure of the solar photosphere that has served wavefront sensors in solar telescopes for decades with useful reference structures, prominences are much more challenging to use: They are faint and their fine structure is barely visible at the short exposures needed for an AO wavefront sensor.
