DMSP satellite observations and magnetic measurements at the Yakutsk observatory (φ=62°N, λ=129.6°E, L=3.3) are used to investigate the characteristics of undulations of the equatorward boundary of diffuse aurora and their relationship to the Pc5 magnetic pulsations in the evening sector during two successive magnetic superstorms at the beginning of November 2004. The large-scale undulations were observed by DMSP satellites near Yakutsk (φ~59-62°) at 0924-0932 UT on November 8, 2004 during the storm recovery phase and at~0841 UT on November 10, 2004 during the main phase of storm. They had the wavelength of λ450-500 km and the the amplitude of A~150 km for the first event, and λ~250 km and A~100 km for the second event, respectively. The estimated velocity of westward propagation for undulations during the first event was equal to V~1.4 km/s. The appearance of undulations for both events near Yakutsk was accompanied by geomagnetic Pc5 pulsations with periods of ~4-8 min, registered at the station. The behavior of undulations and fast plasma flows with concurrent Pc5 pulsations is discussed.

Школьная газета "Пятая Высота" впервые выпускает исторический, мультимедийный подпроект однодневной газеты "Беринг", которая выходит под девизом: Живая история России. Этой работой стираются все традиционные границы школьной газеты. В одном этом номере удалось собрать соавторов не только из разных городов, но и из Дании, родины Беринга. Идея выпуска однодневной газеты реализуется в рамках проекта "Летопись школы N 5" города Якутска. Именно Якутск был форпостом Камчатской экспедиции - здесь Беринг прожил со своей семьей три года, решая вопросы заготовки и доставки провианта в Охотск

Statistical analysis of internal gravity wave parameters registered by variations of the hydroxyl molecule emission is presented. The wave structures are detected with an all sky infrared camera at the optical station of Maimaga (φ=63° N; λ=129.50°E geographic). The data obtained for the period of 1998 to 2002 show that the small-scale internal gravity waves propagate predominantly westward. The observed wavelengths vary from 15.4 to 100 km. (the average value is ~40 km), the horizontal phase speeds are between 19 and 166 m s-¹ (the average value is ~63 m s-¹) and the estimated periods are 9-90 min (the average value is ~17 min). The wavelengths and phase speeds at high latitudes is probably due to the large intensities of the filtering winds compared to those in the middle atmosphere. The short waves (wavelengths shorter than 17.5 km) propagate in the same direction as the long ones.
