We found a number of sources with weak 6.7GHz methanol masers, possibly indicating regions in early stages of star formation. Here we describe the results of follow-up observations that were con- ducted with the Very Large Array in New Mexico to characterize this new population of “weak” 6.7 GHz methanol masers.STAMPAenConference paper10.1017/S1743921318000807https://www.cambridge.org/core/journals/proceedings-of-the-international-astronomical-union/article/vla-observations-of-a-sample-of-lowbrightness-67-ghz-methanol-masers/04AA9F611E0AF9A4F73A86128AF765182018IAUS..336..311OFIS/05 - ASTRONOMIA E ASTROFISICA
