Abstract | We report the results of a month long program of daily observations conducted to study the short-term variability of the H2O maser emission from W51M. During the period of our experiment, we observed significant changes in the flux density of some maser features, but no drift in the velocity of any feature. The flux density of a feature at 82.8 km s(-1) declined from 1140 Jy to 152 Jy over the month-long monitoring program. We tentatively conclude that this variation may be caused by enhanced interstellar scintillation. |
