[en] Detailed analysis of soft (0.1-4keV) X-ray emission from the 1 deg x 1 deg field centered on the star HD 192163 in the nebula NGC 6888 has revealed, besides the nebula, 3 uresolved faint X-ray sources. Two among them are the nearby G-star HD 192020 and HD 192182 with X-ray fluxes=(3-4)x10^-13 and 1x10^-13 ergxcm^-2xs^-1 respectively; the temperature of HD 192020 is 0.17-0.35 keV. A source with the coordinates (1950.0)RA=20^h10^m52^s, DEC=38 deg 01', 0 is not identified. It has the flux F_X=(1.5-3)x10^-13ergxcm^-2xs^-1 and a hard spectrum. Upper limit of flux F_X ∼ 5x10^-14ergxcm^-2xs^-1 is found for a number of 7-9^m stars
