ASH18 - Observations of OH and H₂O Maser Emission in the Star-Forming Region S128

Short title: Ashimbaeva et al. (2018)

Target type: High_mass_SFR,HII
Transitions: OH_1665,OH_1667,OH_1720

Abstract
Results of monitoring hydroxyl and water masers in the star-forming region S128 are presented. A large number of emission features in the 1665 MHz OH line have been detected in both circular polarizations. In spite of the strong variability of the flux density in the main 1665 MHz line, the radial velocities of the features remained constant. Zeeman splitting of the 1720MHz line equal to 0.86 km/s was detected, corresponding to a longitudinal magnetic field of 3.6 mG. The variability of the H²O emission has a cyclic character with a quasi-period of 4-14 yrs. The evolution of individual features confirms that the H²O sources A and B are associated with an ionization front between two colliding CO clouds, and shows that the activity was transferred from maser B to maser A in 1999-2001.
