摘要：

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.
