The purpose of the work is to study the peculiarities of propagation and formation mechanism of this phenomenon. In the first case, the manifestation of a bore in the emissions of hydroxyl OH molecules at the level of the mesopause (altitude 87 km) and the green line of atomic oxygen [OI] (altitude 97 km) is described. In the second case, a description of a bore recorded in the emission of hydroxyl OH molecules is presented. The wavelength, phase velocity of propagation, wave period, direction of propagation, time and duration of the phenomenon, are calculated. Possible sources of formation of the mesospheric bore are also discussed.</p></abstract><trans-abstract xml:lang="ru"><p>Представлено описание двух случаев наблюдения так называемых мезосферных боров, представляющих собой выделяющиеся волновые фронты, по данным регистрации свечения ночного неба камерами всего неба над центральной частью Якутии (северо-восточная часть Сибири). Целью работы является изучение особенности распространения и механизма формирования этого явления. В первом случае описывается проявление бора в излучениях молекул гидроксила OH на уровне мезопаузы (высота 87 км) и зеленой линии атомарного кислорода [OI] (высота 97 км). Во втором случае представлено описание бора, зарегистрированного в эмиссии молекул гидроксила OH. Рассчитаны длина волны, фазовая скорость распространения, период волны, направление распространения, время и продолжительность явления. Обсуждаются возможные источники формирования мезосферного бора.</p></trans-abstract><kwd-group xml:lang="en"><kwd>mesospheric bore</kwd><kwd>internal gravity waves</kwd><kwd>night airglow</kwd><kwd>all-sky camera</kwd><kwd>hydroxyl emission</kwd><kwd>SABER TIMED</kwd><kwd>Aura MLS</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>мезосферный бор</kwd><kwd>внутренние гравитационные волны</kwd><kwd>свечение ночного неба</kwd><kwd>камера всего неба</kwd><kwd>эмиссия гидроксила</kwd><kwd>SABER TIMED</kwd><kwd>Aura MLS</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="ru">Правительство Российской Федерации</institution></institution-wrap><institution-wrap><institution xml:lang="en">Government of the Russian Federation</institution></institution-wrap></funding-source><award-id>122011700172-2</award-id></award-group></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Иванов В.В., Алексеенков Г.А.
