Siphon flow in a cool magnetic loop
C. Bethge, C. Beck, H. Peter +1
We investigate the properties of a structure in the solar chromosphere in an active region to find out whether the feature is consistent with a siphon flow in a magnetic loop fille…
Stray-light contamination and spatial deconvolution of slit-spectrograph observations
C. Beck, R. Rezaei, D. Fabbian
Stray light caused by scattering on optical surfaces and in the Earth's atmosphere degrades the spatial resolution of observations. We study the contribution of stray light to the…
The Chromospheric Telescope
C. Bethge, H. Peter, T. J. Kentischer +3
We introduce the Chromospheric Telescope (ChroTel) at the Observatorio del Teide in Izana on Tenerife as a new multi-wavelength imaging telescope for full-disk synoptic observation…
Spectroscopy at the solar limb: I. Average off-limb profiles and Doppler shifts of Ca II H
C. Beck, R. Rezaei
We present constraints on the structure of the chromosphere from observations of the Ca II H line profile near and off the solar limb. We obtained a data set of the Ca II H line in…
