Using archival data of the Einstein Observatory, X-ray emission from W 63 and HB 21 were found with confidence levels of 7sigma and 5sigma, respectively. For both nebulae, the brightest parts of the X-ray images are the central ones. The X-ray fluxes and luminosities are determined. Two point X-ray sources were found near W 63; the first was the KO111 star BS 7798, while the second was not identified.
