Access to GREGOR Data

Data are publicly available for the GREGOR instruments GRIS, GFPI, and BIC/HiFI. The BBI and ZIMPOL do not yet have a public archive.

If you use GREGOR data, please include the following acknowledgment in your publication:

The 1.5-meter GREGOR solar telescope was built by a German consortium under the leadership of the Institute for Solar Physics (KIS) in Freiburg with the Leibniz Institute for Astrophysics Potsdam, the Institute for Astrophysics Göttingen, and the Max Planck Institute for Solar System Research in Göttingen as partners, and with contributions by the Instituto de Astrofísica de Canarias and the Astronomical Institute of the Academy of Sciences of the Czech Republic.

Please cite also the respective instrument papers from the special issue of Astronomische Nachrichten (Vol. 333/9), especially Schmidt et al.2012, AN 333/9, 796 and Kleint et al. 2020, A&A, 641, A27 (https://arxiv.org/abs/2006.11875).

GRIS Archiv

The data archive is hosted at the Leibniz-Institute for Solar Physics and can be accessed with the following link:


The most used configuration is the spectropolarimetric mode taking data at 1083 nm. For some observing days, spectropolarimetric data at 1565 nm or spectroscopic data sets exist. The archive shows preview maps of the Stokes vector for each data set alongside context information like exposure time, time of observation, and context images of the Sun. All data are calibrated (level 1 data) using the most recent version of the data pipeline that is provided by the instrument PI Manolo Collados (IAC). For the 1.56µm regime we additionally provide level 2 data from profile analyses consisting of Dopplermaps, maps of strength and orientation of the magnetic field, etc. For your convenience we recommend wget to download multiple files.

GREGOR Slit Jaw Cameras

The GSJC are context imaging cameras for GRIS. Usually, gsjc1 is run with a Lyot filter for H-alpha (6563 A, FWHM 0.5 A) showing the chromosphere and gsjc2 shows the continuum at 7770 A. Quicklook movies exist for each observing day:

The data reduction code is installed at OT. Instructions to run the pipeline can be obtained by Lucia Kleint.


The GFPI, BIC and HiFI data are currently hosted at the AIP, which is operating the instruments. Please see:
