Abstract

The extreme ultraviolet (EUV) imaging spectrometer (EIS) onboard the Hinode mission has been observing for more than a decade since its launch the profiles of EUV emission lines originating from high-temperature solar outer atmospheres with its high dispersion spectrograms for the first time in solar EUV spectroscopy. The EIS has been ice-breaking difficult problems and obtaining a plenty of important scientific results. The EIS has since entered an epoch of “sunrise” in solar EUV spectroscopy. Scientific outputs thawed out by EIS are briefly discussed, and key emission lines in hot and dynamic postglacial periods of solar EUV spectroscopy are highlighted.
