Mg II Lines Observed During the X-class Flare on 29 March 2014 by the Interface Region Imaging Spectrograph
Heinzel, P.; Liu, W.; Kleint, L. +1 more
Mg II lines represent one of the strongest emissions from the chromospheric plasma during solar flares. In this article, we studied the Mg II lines observed during the X1 flare on 29 March 2014 (SOL2014-03-29T17:48) by the Interface Region Imaging Spectrograph (IRIS). IRIS detected large intensity enhancements of the Mg II h and k lines, subordina…
Limb Event Brightenings and Fast Ejection Using IRIS Mission Observations
Koutchmy, S.; Golub, L.; Tavabi, E.
The Interface Region Imaging Spectrograph (IRIS) of the recently commissioned NASA small explorer mission provides significantly more complete and higher resolution spectral coverage of the dynamical conditions inside the chromosphere and transition region (TR) than has been available ever before. High temporal, spatial (0.3″) and spect…
High-Resolution Observations of a Flux Rope with the Interface Region Imaging Spectrograph
Li, Ting; Zhang, Jun
We report the observations of a flux rope at transition region temperatures with the Interface Region Imaging Spectrograph (IRIS) on 30 August 2014. Initially, magnetic flux cancellation continually took place and a filament was activated. Then the bright material from the filament moved southward and tracked out several fine structures. These fin…
