The results of monitoring the 1.6-GHz hydroxyl and 6.7-GHz methanol masers in the star-forming region G 351.78 — 0.54 from 1993 to mid-1995 are reported. Variations with time-scales of a few months are superimposed on long-term changes with a time-scale of years in the brightest 1.665- and 1.667-GHz maser peaks and in both 6.7-GHz maser peaks. The methanol maser feature at +1.2 km s−1 flared at le...
