Abstract: 

Spektr-RG Orbital Observatory with Russian ART-XC and German eRosita X-ray telescopes aboard was launched on July 13th of 2019 from Baykonur. During the flight to the L2 point of the Sun-Earth system, SRG performed calibrations and long duration detailed Performance Verification Observations of more than a dozen of the targets.

Starting in the middle of December during half of the year the SRG Observatory scanned the whole sky and discovered more than a million point X-Ray sources, mainly AGNs and QSOs, stars with hot and bright coronae, more than 16 thousand clusters of galaxies. SRG constructed the X-Ray map of the whole sky, which is now seems to be the best among existing. It provides a lot of information about the distribution of absorbing gas in the Milky Way and provides a beautiful image of the North Polar Spur and similar bright emitting feature on another side from
the Central Part of the Galaxy.

I plan to find time to explain the plans of the Observatory for the future, to demonstrate several images from PV phase observations and from the second whole sky survey which is going now.
