摘要：
The class II methanol maser source G9.62+0.20E has been monitored since 1999 at 6.7 GHz and since 2000 at 12.2 GHz. Six flares have been observed to date. These flares are periodic, with an interval of 246 d between flares. The duration of the flare is approximately 3 months, with maximum amplitude reached a month after the start of the flare.
