First Detection of Solar Flare Emission in Middle-Ultraviolet Balmer Continuum
Marie Dominique, Andrei N. Zhukov, Petr Heinzel +8
We present the first detection of solar flare emission at middle-ultraviolet wavelengths around 2000 A by the channel 2 of the Large-Yield RAdiometer (LYRA) onboard the PROBA2 miss…
High-Density Off-Limb Flare Loops Observed by SDO
S. Jejčič, L. Kleint, P. Heinzel
The density distribution of flare loops and the mechanisms of their emission in the continuum are still open questions. On September 10, 2017 a prominent loop system appeared durin…
Statistical analysis of UV spectra of a quiescent prominence observed by IRIS
S. Jejčič, P. Schwartz, P. Heinzel +2
The paper analyzes the structure and dynamics of a quiescent prominence that occurred on October 22, 2013. We aim to determine the physical characteristics of the observed prominen…
Hot prominence detected in the core of a Coronal Mass Ejection: III. Plasma filling factor from UVCS Lyman- and Lyman- observations
R. Susino, A. Bemporad, S. Jejčič +1
This work deals with the study of an erupting prominence embedded in the core of a CME and focuses on the derivation of the prominence plasma filling factor. We explore two methods…
Solar ultraviolet bursts
Peter R. Young, Hui Tian, Hardi Peter +16
The term "ultraviolet (UV) burst" is introduced to describe small, intense, transient brightenings in ultraviolet images of solar active regions. We inventorize their properties an…
Blue wing enhancement of the chromospheric Mg II h and k lines in a solar flare
Akiko Tei, Takahito Sakaue, Takenori J. Okamoto +6
We performed coordinated observations of AR 12205, which produced a C-class flare on 2014 November 11, with the Interface Region Imaging Spectrograph (IRIS) and the Domeless Solar…
