Extreme-Ultraviolet Emission from Solar Prominences
Spectra and spectroheliograms of prominences have been obtained at wavelengths of 300 to 1400 A from instruments aboard the OSO 4 and OSO 6 spacecraft. Quiescent prominences appear in emission above the limb for all strong lines formed at temperatures below 300,000 K, but not at higher temperatures.

Explosive events in the solar atmosphere seen in extreme-ultraviolet emission lines [PDF]
We present observations of explosive events (EEs) in the solar atmosphere obtained with the Solar Ultraviolet Measurements of Emitted Radiation (SUMER) spectrometer on the Solar and Heliospheric Observatory (SOHO) in the wavelength range from about 750 A to 790 A.

Measurements of extreme-ultraviolet emission-line profiles near the solar limb
Line profiles of optically thin extreme-ultraviolet emission lines observed in a quiet sun region at positions within and above the white-light limb with the NRL slit spectrograph (S082-B) on Skylab are discussed. Absolute line intensities and full widths at half-maximum are presented for lines formed over the temperature range from about 10,000 to 22 ...

Radiative Hydrodynamic Models of the Optical and Ultraviolet Emission from Solar Flares [PDF]
We report on radiative hydrodynamic simulations of moderate and strong solar flares. The flares were simulated by calculating the atmospheric response to a beam of non-thermal electrons injected at the apex of a one-dimensional closed coronal loop, and include heating from thermal soft X-ray, extreme ultraviolet and ultraviolet (XEUV) emission.

Coronal Microjets in Quiet-Sun Regions Observed with the Extreme Ultraviolet Imager on Board the Solar Orbiter [PDF]
We report the smallest coronal jets ever observed in the quiet Sun with recent high-resolution observations from the High Resolution Telescopes (HRIEUV and HRILyα ) of the Extreme Ultraviolet Imager on board the Solar Orbiter (SO).

Proxy-based Prediction of Solar Extreme Ultraviolet Emission Using Deep Learning [PDF]
Abstract High-energy radiation from the Sun governs the behavior of Earth’s upper atmosphere and such radiation from any planet-hosting star can drive the long-term evolution of a planetary atmosphere. However, much of this radiation is unobservable because of absorption by Earth’s atmosphere and the interstellar medium.

Image Super-resolution Methods for FY-3E X-EUVI 195 Å Solar Images
Solar eruptions and the solar wind are sources of space weather disturbances, and extreme-ultraviolet (EUV) observations are widely used to research solar activity and space weather forecasts.
