Calibration of full-disk He I 10830 Å filtergrams of the Chromospheric Telescope
Zili Shen, Andrea Diercke, Carsten Denker
The Chromospheric Telescope (ChroTel) is a small 10-cm robotic telescope at Observatorio del Teide on Tenerife (Spain), which observes the entire Sun in H, CaII K, and HeI 10830…
Temporal evolution of arch filaments as seen in He I 10830 Å
S. J. González Manrique, C. Kuckein, M. Collados +7
We study the evolution of an arch filament system (AFS) and of its individual arch filaments to learn about the processes occurring in them. We observed the AFS at the GREGOR solar…
Photospheric Magnetic Fields of the Trailing Sunspots in Active Region NOAA 12396
M. Verma, H. Balthasar, C. Denker +27
The solar magnetic field is responsible for all aspects of solar activity. Sunspots are the main manifestation of the ensuing solar activity. Combining high-resolution and synoptic…
High-Cadence Imaging and Imaging Spectroscopy at the GREGOR Solar Telescope - A Collaborative Research Environment for High-Resolution Solar Physics
C. Denker, C. Kuckein, M. Verma +7
In high-resolution solar physics, the volume and complexity of photometric, spectroscopic, and polarimetric ground-based data significantly increased in the last decade reaching da…
Image Quality in High-resolution and High-cadence Solar Imaging
C. Denker, E. Dineva, H. Balthasar +4
Broad-band imaging and even imaging with a moderate bandpass (about 1 nm) provides a "photon-rich" environment, where frame selection ("lucky imaging") becomes a helpful tool in im…
