| Abstract: | Six young bipolar outflows in regions of low-intermediate-mass star formation were observed in the 70-61

E methanol lines at 44, 95, and 84 GHz, respectively. Narrow features were detected towards NGC 1333-IRS4A, HH 25MMS, and L1157-B1.
The flux densities of the detected lines are not higher than 11 Jy, which is much lower than the flux densities of strong
maser lines in regions of high-mass star formation. Analysis shows that the narrow features are most likely masers.
