Filigree in the Surroundings of Polar Crown and High-Latitude Filaments
A. Diercke, C. Kuckein, M. Verma +1
High-resolution observations of polar crown and high-latitude filaments are scarce. We present a unique sample of such filaments observed in high-resolution H narrow-band filter…
Classification of High-resolution Solar Hα Spectra using t-distributed Stochastic Neighbor Embedding
Meetu Verma, Gal Matijevič, Carsten Denker +7
The Hα spectral line is a well-studied absorption line revealing properties of the highly structured and dynamic solar chromosphere. Typical features with distinct spectral signatu…
Observational study of chromospheric heating by acoustic waves
V. Abbasvand, M. Sobotka, M. Švanda +9
Aims. To investigate the role of acoustic and magneto-acoustic waves in heating the solar chromosphere, observations in strong chromospheric lines are analyzed by comparing the dep…
High-resolution spectroscopy of an erupting minifilament and its impact on the nearby chromosphere
I. Kontogiannis, E. Dineva, A. Diercke +4
We study the evolution of a mini-filament eruption in a quiet region at the center of the solar disk and its impact on the ambient atmosphere. We used high-spectral resolution imag…
Magnetic Flux Emergence in a Coronal Hole
J. Palacios, D. Utz, S. Hofmeister +13
A joint campaign of various space-borne and ground-based observatories, comprising the Japanese Hinode mission (HOP~338, 20\,--\,30~September 2017), the GREGOR solar telescope, and…
High-resolution spectroscopy of a surge in an emerging flux region
M. Verma, C. Denker, A. Diercke +6
High-spectral resolution observations using the VTT echelle spectrograph in the chromospheric H line were obtained in the early growth phase of active region NOAA 12722. Noise-s…
