Measuring Plasma Flows in Transition Region Loops Using the MOSES Instrument
Abstract
While traditional slit spectrographs have been extremely valuable for observing coronal loops, the narrow slit of these instruments does not allow the properties and dynamic evolution of coronal loops to be measured simultaneously across their entire structure. The Multi-Order Solar EUV Spectrograph (MOSES) is a rocket-borne slitless spectrograph capable of measuring doppler shifts simultaneously over a wide field of view. On August 27, 2015, we observed AR 12403 in Ne VII (46.5 nm) at T ~ 500,000 K. We present time dependent measurements of downflow velocities for loop footpoints, with physical interpretation based on 1D modeling.
