Three Dimensional Structure Of A Complex Bipolar Jet: Transition Region Imaging-spectroscopy With MOSES
Abstract
We report on an interesting transient brightening observed in He II 304 Å above a flux-canceling magnetic bipole during the MOSES (Multi-Order Solar EUV Spectrograph) sounding rocket flight, Feb. 8, 2006. The event resembles a bipolar jet and has characteristics of a transition region explosive event, but it is not a simple, linear structure at some angle to the line-of-sight. The jets curve away from the axis of a compact, bright core, and are not collinear. We observe transverse sky-plane motions and infer line-of-sight doppler shifts along the length of the jets, as well as non-thermal line broadening in the bright core, demonstrating the utility of simultaneous imaging-spectroscopy provided by MOSES. This work is supported by NASA LCAS and the Montana Space Grant Consortium.
