Spectropolarimetric observations of the Ca II 8498 A and 8542 A lines in the quiet Sun
A. Pietarila, H. Socas-Navarro, T. Bogdan
The Ca II infrared triplet is one of the few magnetically sensitive chromospheric lines available for ground-based observations. We present spectropolarimetric observations of the…
SPINOR: Visible and Infrared Spectro-Polarimetry at the National Solar Observatory
H. Socas-Navarro, D. Elmore, A. Pietarila +3
SPINOR is a new spectro-polarimeter that will serve as a facility instrument for the Dunn Solar Telescope at the National Solar Observatory. This instrument is capable of achromati…
Spectro-polarimetric observations and non-LTE Modeling of Ellerman bombs
H. Socas-Navarro, V. Martinez Pillet, D. Elmore +3
Ellerman bombs are bright emission features observed in the wings of H, usually in the vicinity of magnetic concentrations. Here we show that they can also be detected in the Ca…
