Abstract: We present further radio observations of V838 Mon in the SiO and several other molecular lines after 2005 April. The detection of SiO masers in this object indicates that the star formed after eruption is indeed a cool masslosing object with circumstellar masers. Further observations of SiO masers found a sudden increase within a few months and succeeding flattening of maser intensities, suggesting a sudden slow onset of mass-loss from the central star after the 2002 eruption. A detection of CO emission 30″ north of the star is also reported. A possible implication for stellar evolution in related objects is given.
