<\/a> GREGOR<\/a> is Europe’s largest solar telescope, located on a 2300-meter-high mountain ridge at Iza\u00f1a on the Canary Island of Tenerife. The telescope was developed and built under the leadership of the Kiepenheuer Institute for Solar Physics (KIS<\/a>) in Freiburg with the Leibniz Institute for Astrophysics Potsdam (AIP<\/a>), the Institute for Astrophysics G\u00f6ttingen (IAG<\/a>), and the Max Planck Institute for Solar System Research (MPS<\/a>) in G\u00f6ttingen as domestic partners and with the Instituto de Astrof\u00edsica de Canarias (IAC<\/a>) and the Astronomical Institute of the Academy of Sciences (AIAS<\/a>) of the Czech Republic as international partners. The telescope was inaugurated on 2012 May 21 and has started in early 2014 its \u00bbearly science\u00ab phase with access restricted to the GREGOR partners. In the future, GREGOR access will be granted as part of the SOLARNET access program.<\/p>\nThe GREGOR Fabry-P\u00e9rot Interferometer All GFPI, BIC, and HiFI data arebe made accessible on this website, initially only for GREGOR partners but in the future also for the general public. Various processing levels will be offered (raw, quick-look, and processed) because data analysis methods can differ significantly depending on the observed solar feature and the intended science case. The GREGOR archive at AIP is a collaborative effort of the R&D Section \u00bbSupercomputing and E-Science<\/a>\u00ab and the Research Group \u00bbOptical Solar Physics<\/a>\u00ab.<\/p>\n","protected":false},"excerpt":{"rendered":" The 1.5-meter-aperture GREGOR is Europe’s largest solar telescope, located on a 2300-meter-high mountain ridge at Iza\u00f1a on the Canary Island of Tenerife.

<\/a> (GFPI<\/a>) traces its roots back to the G\u00f6ttingen Fabry-P\u00e9rot Interferometer, which was developed and build by IAG. Nowadays, the GFPI is operated by AIP. This first-light instrument is an imaging spectropolarimeter for high-resolution photospheric and chromospheric observations in the wavelength range 530\u2013870\u2009nm. In addition, its\u00a0 Blue Imaging Channel (BIC<\/a>) can be used with a variety of interference filters and several facility CCD cameras (pco.4000 and pco.sensicam) for high-cadence imaging and subsequent image restoration in the blue wavelength region 390\u2013530\u2009nm. In 2016, BIC was replaced with the High-Resolution Fast Imager (HiFI). Dichroic beamsplitters also enable simultaneous observations with the Grating Infrared Spectrograph (GRIS<\/a>) in the near-infrared 1-2.5\u2009\u00b5m, which was designed and build by IAC.<\/p>\n
