What Can FLCT and MOSES Tell Us About the Transition Region?
Abstract
Local correlation tracking methods are often used to measure displacement, deformation, strain, and flow in varying fields of study. The Fourier Local Correlation Tracking (FLCT) technique described by Fisher & Welch (2007) is used to track flows on varying scales observed by the Multi-Order Solar EUV Spectrograph (MOSES), a slitless spectrograph imaging in narrowband He II 304 Å. The high spatial resolution (0.6”) and wide field of view (10’ x 20’) combined with the cotemporal spectral data obtained by the MOSES instrument provides a unique range of transition region features and spectral information that may be analyzed using FLCT techniques. Results are reported using FLCT to evaluate small scale flows. The feasibility of extending the technique to include larger scale motions and analysis of spectral information is also considered.
