- Аннотация: The results of a study of the variability of maser emission in OH lines in the 18 cm range in the G10.624-0.385 star formation region from monitoring data performed at the Large Radio Telescope in Nançay (France) in 2008-2023 are presented. It is obtained that for a Zeeman pair in line 1667 MHz splitting (about 1.96 km/s) and, consequently, the magnitude of the longitudinal magnetic field have been stable for more than 25 years. In the satellite lines of 1612 and 1720 MHz, broadband absorption and emission are observed, respectively. The mirrored profiles of the OH 1612 and 1720 MHz satellite lines indicate that the levels of the corresponding transitions are pumped by IR radiation from a source immersed in a magnetized molecular cloud around the OH maser. Spatial identification of features in both main lines is carried out. It is found that the transverse magnetic field is directed mainly along some organized structure in the form of an arc.
