We report spectral line observations of the H 2 O maser at 22 GHz, the methanol maser transitions at 6.7, 12.2, and 44 GHz, and the continuum in these same frequency bands with The Karl G. Jansky Very Large Array at the post-burst epoch of 2017. For the first time, maps of 22 GHz H 2 O and 44 GHz CH 3 OH maser spots are obtained and the absolute position of the 22 GHz H 2 O bursting feature is determined with milliarcsecond precision. We detected four continuum components, three of which are closely spaced in a linear orientation, suggesting a physical link between them. � 2019. The American Astronomical Society.
