New solar telescope GREGOR

The 1.5 m solar telescope GREGOR was built at the Observatorio del Teide by a German consortium led by the Kiepenheuer-Institut für Sonnenphysik, with the Leibniz-Institut für Astrophysik Potsdam, the Max-Planck-Institut für Sonnensystemforschung Lindau and the Institut für Astrophysik Göttingen (until 2008) as partners. The Instituto de Astrofísica de Canarias and the Astromomical Institute of the Academey of Sciences of the Czech Republic contributed to the telescope or the instrumentation.

 

GREGOR is the largest solar telescope in Europe. It it designed for observations of the solar photosphere and chromosphere in the visible and near infrared. Presently it is equipped with the following post-focus instruments for solar observations:

-a multi-channel high-resolution imager

- a filter spectrometer for the measurement of material flows and magnetic field in different layers of the solar atmosphere

- a grating spectro-pollarimeter for the near infrared (1.0 to 2.2 µm)

GREGOR is equipped with a high-order adaptive optics. This system is presently (2014) being upgraded to a multi-conjugated adaptive optics system.

From 2014 on GREGOR will be used for scientific observations.
