- ПубликацияТолько метаданныеInvesigation of the Local Anisotropy of Cosmic Ray Muon Flux During Coronal Mass Ejections in 2007–2018(2019) Astapov, I. I.; Barbashina, N. S.; Dmitrieva, A. N.; Konovalova, A. Y.; Osetrova, N. V.; Shutenko, V. V.; Yashin, I. I.; Астапов, Иван Иванович; Барбашина, Наталья Сергеевна; Дмитриева, Анна Николаевна; Коновалова, Алена Юрьевна; Шутенко, Виктор Викторович; Яшин, Игорь Иванович© 2019, Pleiades Publishing, Ltd.Coronal mass ejections are among the most powerful disturbances of the interplanetary space. They can influence the state of the near-Earth space, including magnetosphere of the Earth. In addition, such disturbances modulate the flux of cosmic rays and penetrate both the heliosphere and the Earth’s magnetosphere. In order to find an early alert of such events, it is necessary to investigate the flux of particles arriving to the Earth and providing information about events in the heliosphere. The paper presents the results of investigation of the anisotropy of the cosmic ray muon flux by means of the muon hodoscope URAGAN in the period from 2007 to 2018.

It includes several facilities for studying the electron–photon, muon, and hadron components of the EAS in the energy range of 1 PeV to 1 EeV. This work presents the first results for two months of the joint operation of five facilities (NEVOD-EAS, CWD, CTS, PRISMA-32, and DECOR). The problems of synchronizing the facilities and selecting joint events are considered. The experimental data of these facilities are analyzed for different components of the EAS in overlapping energy ranges.

The dependences of the energy deposit of muon bundles on the zenith angle and the local muon density are obtained for primary energies of 10–1000 PeV. The results from comparing the data to simulations performed with the CORSIKA program are presented.
- ПубликацияТолько метаданныеReal-Time GSE Mapping of Muon-Flux Directional Variation with the URAGAN Hodoscope(2019) Yashin, I. I.; Astapov, I. I.; Barbashina, N. S.; Dmitrieva, A. N.; Kompaniets, K. G.; Petrukhin, A. A.; Shutenko, V. V.; Яшин, Игорь Иванович; Астапов, Иван Иванович; Барбашина, Наталья Сергеевна; Дмитриева, Анна Николаевна; Компаниец, Константин Георгиевич; Петрухин, Анатолий Афанасьевич; Шутенко, Виктор Викторович© 2019, Allerton Press, Inc.Abstract: Continuous monitoring of the muon flux over wide ranges of zenith and azimuth angles with the URAGAN detector (Moscow, 55.7° N, 37.7° E, 173 m AMSL) allows detection of variations in its intensity and angular distribution. A way of locating domains of anisotropy in the muon angular distribution is described, and they are mapped in matrix form in the GSE coordinate system. The maximum depth (height) of deformation, the zenith and azimuth angles of the center in the local system, and its GSE longitude and latitude are determined for each observed domain. The GSE longitudes of the detected domains of anisotropy are available on the Internet as functions of time and can be used to monitor the heliosphere’s activity.
