Journal: Monthly Notices of the Royal Astronomical Society, Vol. 269, 257-264 (1994)

Transitions: OH_1665,OH_1667,CH3OH_12(II)

Abstract
18 new 12.2-GHz methanol masers and eight new 1.6-GHz hydroxyl masers have been detected towards 66 6.7-GHz methanol masers discovered in recent searches of infrared sources. The newly detected hydroxyl masers in IRAS 17589-2312 appear to have turned on in the last 15 years. The masers seen in both methanol transitions in IRAS 15122-5801 were observed to flare and decay on a time-scale of months. Key words: masers - ISM: molecules - radio lines: ISM.
