Quiet-Sun hydrogen Lyman-alpha line profile derived from SOHO/SUMER solar-disk observations
S. Gunar, P. Schwartz, J. Koza +1
The solar radiation in the Lyman-alpha spectral line of hydrogen plays a significant role in the illumination of chromospheric and coronal structures, such as prominences, spicules…
Signatures of Helium continuum in cool flare loops observed by SDO/AIA
Petr Heinzel, Pavol Schwartz, Juraj Lörinčík +3
We present an analysis of off-limb cool flare loops observed by SDO/AIA during the gradual phase of SOL2017-09-10T16:06 X8.2-class flare. In the EUV channels starting from the 335…
Cloud model inversions of strong chromospheric absorption lines using principal component analysis
Ekaterina Dineva, Meetu Verma, Sergio Javier González Manrique +2
High-resolution spectroscopy of strong chromospheric absorption lines delivers nowadays several millions of spectra per observing day, when using fast scanning devices to cover lar…
Coordinated observations between China and Europe to follow active region 12709
S. J. González Manrique, C. Kuckein, P. Gömöry +5
We present the first images of a coordinated campaign to follow active region NOAA 12709 on 2018 May 13 as part of a joint effort between three observatories (China-Europe). The ac…
2D non-LTE modelling of a filament observed in the H_alpha line with the DST/IBIS spectropolarimeter
P. Schwartz, S. Gunar, J. M. Jenkins +3
We study a fragment of a large quiescent filament observed on May 29, 2017 by the Interferometric BIdimensional Spectropolarimeter (IBIS) mounted at the Dunn Solar Telescope. We fo…
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…
