Abstract:
The EUV Snapshot Imaging Spectrograph (ESIS) was launched on board a sounding rocket on September 30th, 2019 from White Sands Missile Range. ESIS is a slitless spectrograph that captures spectral line profiles over an extended field of view in a single "snapshot". Since each of the four ESIS channels contains a unique combination of spatial and spectral information it must be inverted to recover a line profile at each spatial pixel. We present a preliminary inversion of the O V 630 angstrom images captured by ESIS and an interpretation of line profiles associated with several solar transient events within.
