Abstract (from CDS):

We report the results of our third survey for formaldehyde (H2CO) 6 cm maser emission in the Galaxy. Using the Very Large Array, we detected two new H2 CO maser sources (G23.01-0.41 and G25.83-0.18), thus increasing the sample of known H2 CO maser regions in the Galaxy to seven. We review the characteristics of the G23.01-0.41 and G25.83-0.18 star-forming regions. The H2 CO masers in G23.01-0.41 and G25.83-0.18 share several properties with the other known H2 CO masers, in particular, emission from rich maser environments and close proximity to very young massive stellar objects.
