Summary:
Imaging instruments are required to capture flares and study the transport of mass, momentum and energy through the solar atmosphere. Of NASA's fleet of spacecraft, SDO provides full Sun magnetic and thermal data every few seconds at 1" resolution. The SDO/AIA UV (160nm) and EUV channels observe material above and at the base of the chromosphere, omitting several scale heights between the chromosphere and corona. From 2012, the UV slit spectrometer IRIS will partly plug this gap by making rapid rasters of chromospheric features. We propose to augment these capabilities using, in particular, the IBIS imaging spectropolarimeter at Sacramento Peak Observatory, and applying sophisticated spectral line inversion techniques to full Stokes photospheric and chromospheric data. Our goal is to investigate the 3D magnetic field configurations in the solar atmosphere necessary for flares to occur and their changes during and after flares.Performance Year | Reference | Investigation Type | Actions |
