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 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 (JVLA) 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.
