Abstract

The source G25.65+1.05 (RAFGL7009S, IRAS 18316-0602) is the least studied of the three regions of massive star formation known to show exceptionally powerful H_2_O maser bursts. We report spectral line observations of the H_2_O maser at 22GHz, the methanol maser transitions at 6.7, 12.2, and 44GHz, 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 22GHz H_2_O and 44GHz CH_3_OH maser spots are obtained and the absolute position of the 22GHz 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.
