On August 26, 2019 the first X-ray image was obtained by one of the seven eROSITA telescope modules on board the Spektr-RG space observatory.
The image of the UDS field with an area of the order of one square degree clearly shows dozens of X-ray sources, mainly active galactic nuclei and quasars. The image was obtained with the exposure of about 2000 seconds in the 0.5–2 keV energy range. Data obtained by Russian and German consortiums of the SRG/eROSITA mission.
