The field just West of the galactic supernova remnant W28 (l=6.4{deg}, b=-0.2{deg}) harbors 3 of 5 newly-discovered 1720 OH maser spots and two recently-discovered candidate supernova candidates (one of which is a gamma-ray source), as well as several compact and classical HII regions. The aims is to show the interaction of radio supernova remnants with ambient molecular gas in sky field just West of W28.
