X-ray observations of three Shakhbazyan's Compact Groups of Galaxies, SCGG 202, SCGG 205, and SCGG 223, are presented for the first time. Extended X-ray emission was detected from SCGG 202 and SCGG 223 with 0.5-2 keV luminosity of 1 × 10 42 erg s −1 and 3 × 10 42 erg s −1 (for H 0 = 75 km s −1 Mpc −1 ), respectively, while no significant emission was detected from SCGG 205 with an upper limit of 0.7 × 10 42 erg s −1 . The X-ray spectra of SCGG 202 and SCGG 223 can be described with thin-thermal plasma emission with temperature about 1 keV. X-ray properties of SCGG 202 and SCGG 223 are in good agreement with those of other known groups of galaxies, proving the physical nature of their grouping.
