Abstract
We present a catalog of sources detected by the Mikhail Pavlinsky ART-XC telescope onboard the SRG space observatory during the observations of the Galactic plane region near a longitude \(l\simeq 20^{\circ}\) (L20 field) in October 2019. The L20 field was observed four times in the scanning mode, which provided a uniform coverage of the sky region with a total area of \({\simeq}24\text{ deg}^{2}\) with a median sensitivity of \(8\times 10^{-13}\) erg s\({}^{-1}\) cm\({}^{-2}\) (at 50\(\%\) detection completeness) in the 4–12 keV energy band. As a result, we have detected 29 X-ray sources at a statistically significant level, 11 of which have not been detected previously by other X-ray observatories. Preliminary estimates show that four of them can presumably be extragalactic in nature. We also show that the source SRGA J183220.1\(-\)103508 (CXOGSG J183220.8\(-\)103510) is most likely a galaxy cluster containing a bright radio galaxy at redshift \(z\simeq 0.121\).

ACKNOWLEDGMENTS
In this study we used data from the Mikhail Pavlinsky ART-XC telescope onboard the Spectrum–Roentgen–Gamma (SRG) observatory. The SRG observatory was designed by the Lavochkin Association (enters into the Roskosmos State Corporation) with the participation of the Deutsches Zentrum für Luft- und Raumfahrt (DLR) within the framework of the Russian Federal Space Program on the order of the Russian Academy of Sciences. The ART-XC team thanks the Roskosmos State Corporation, the Russian Academy of Sciences, and the Rosatom State Corporation for supporting the design and production of the ART-XC telescope and the Lavochkin Association and partners for the production and work with the spacecraft and the Navigator platform.
Funding
