   <abstract xml:lang="ru">
    <p>С помощью радиотелескопа РТ-22 в Симеизе проведен мониторинг линий метанола СН3ОН на частотах 19.967 ГГц (переход 21 → 30 Е) и 20.971 ГГц (переход 101 → 112 А) в направлении на массивную область активного звездообразования G358.931-0.030. Зафиксированы две вспышки мазерного излучения. Проведен мониторинг вспышечного явления, произошедшего на частоте 19.967 ГГц. Галактические тесные двойные системы, состоящие из массивных звезд, находящихся на стадии предшествующей главной последовательности, могут быть мощными источниками гравитационных волн.</p>

    <p>Using radiotelescope RT-22 in Simeiz, methanol lines of CH3OH were monitored at frequencies of 19.967 GHz (transition 21 → 30 Е) and 20.971 GHz (transition 101 → 112 A) in the direction of the massive region of active star formation G358.931-0.030. Two flashes of maser radiation were recorded. Monitoring of the flare-up event that occurred at a frequency of 19.967 GHz was preached. Galactic close binary systems, consisting of massive stars at the stage of the preceding main sequence, can be powerful sources of gravitational waves.</p>
