   <abstract xml:lang="ru">
    <p>Проведено сравнение влияния геомагнитных возмущений во время магнитных бурь различных типов (CME и CIR) и во время изолированной суббури на сцинтилляции сигналов спутников ГЛОНАСС и GPS с использованием приемника Septentrio PolaRx5, установленного в г. Апатиты (Мурманская область, Россия). Проанализированы данные наблюдений за 2021 г. Детально рассмотрены магнитные бури 3–4 ноября 2021 г. и 11–12 октября 2021 г. Магнитная буря 3–4 ноября 2021 г. была одной из наиболее мощных за последние годы. Анализ показывает, что наибольших значений фазовый индекс сцинтилляций достигает во время ночных и вечерних суббурь (σϕ≈1.5–1.8), сопровождающихся отрицательной бухтой в магнитном поле. Однако во время магнитных бурь положительные бухты   в магнитном поле, связанные с усилением восточного электроджета, приводят к вполне сопоставимым значениям σϕ. &#13;
Рост фазовых сцинтилляций во время ночных  и вечерних возмущений коррелирует с ростом интенсивности УНЧ-волн (Pi3/Pc5 пульсации) и появлением дуг полярных сияний. Это подтверждает важную роль УНЧ-волн в формировании авроральной дуги и развитии ионосферных неоднородностей. Преобладание зеленой линии в спектре полярных сияний говорит о вкладе возмущений в E-слое ионосферы в рост фазовых сцинтилляций. Пульсирующие полярные сияния, связанные с ионосферными возмущениями в D-слое, не сопровождаются заметным ростом фазовых сцинтилляций. Анализ критических частот ионосферы по данным ионозонда на гидрометеорологической станции «Ловозеро» говорит о формировании спорадического Es-слоя ионосферы во время роста фазовых сцинтилляций.&#13;
Разница в значении фазовых сцинтилляций на спутниках ГЛОНАСС и GPS в период отдельных возмущений может достигать 1.5 раз, что может быть связано с различными орбитами спутников. При этом уровень ГЛОНАСС/GPS-сцинтилляций на частоте L2 выше, чем на частоте L1. Увеличения амплитудного индекса сцинтилляций во время рассматриваемых событий не обнаружено.</p>

   <trans-abstract xml:lang="en">
    <p>We have compared effects of geomagnetic disturbances during magnetic storms of various types (CME and CIR) and during an isolated substorm on scintillations of GLONASS and GPS signals, using a Septentrio PolaRx5 receiver installed in Apatity (Murmansk Region, Russia). We analyze observational data for 2021. The magnetic storms of November 3–4, 2021 and October 11–12, 2021 are examined in detail. The November 3–4, 2021 magnetic storm was one of the most powerful in recent years. The analysis shows that the scintillation phase index reaches its highest values during nighttime and evening substorms (σϕ≈1.5–1.8), accompanied by a negative bay in the magnetic field. During magnetic storms, positive bays in the magnetic field, associated with an increase in the eastward electrojet, lead, however, to quite comparable values of the phase scintillation index.&#13;
An increase in phase scintillations during nighttime and evening disturbances correlates with an increase in the intensity of ULF waves (Pi3/Pc5 pulsations) and with the appearance of aurora arcs. This confirms the important role of ULF waves in forming the auroral arc and in developing ionospheric irregularities. The predominance of the green line in the spectrum of auroras indicates the contribution of disturbances in the ionospheric E layer to the scintillation increase. Pulsating auroras, associated with ionospheric disturbances in the D layer, do not lead to a noticeable increase in phase scintillations. Analysis of ionospheric critical frequencies according to ionosonde data from the Lovozero Hydrometeorological Station indicates the contribution of the sporadic Es layer of the ionosphere to jumps in phase scintillations.&#13;
The difference between phase scintillation values on GLONASS and GPS satellites during individual disturbances can be as great as 1.5 times, which may be due to different orbits of the satellites. At the same time, the level of GLONASS/GPS scintillations at the L2 frequency is higher than at the L1 frequency. We did not find an increase in the amplitude index of scintillations during the events considered.</p>
