    Studying Powerful Coronal Mass Ejections That Occurred in September 2017, According to Data from the URAGAN Muon Hodoscope

    © 2019, Allerton Press, Inc.Abstract: At the beginning of September 2017, the Sun was characterized by anomalously high solar activity (SA), which was unusual for the region of the minimum of the 11-year cycle. A great many powerful flares of the M- and X-classes were observed; these were accompanied by powerful coronal mass ejections (CMEs). These events caused strong magnetic storms on the Earth (the Kp index was as high as 8; the Dst index was <−140 nT). In this work, the effect these ejections had on the flux of cosmic rays (CRs) is considered using data from the URAGAN muon hodoscope at the Moscow Engineering Physics Institute. The study is based on an analysis of variations in the cosmic ray muon flux. Results are presented from processing flux intensity via flicker-noise spectroscopy in order to identify geoeffective disturbances of the Earth’s magnetosphere. A predictor that precedes by more than one day the emergence in near-Earth space of disturbances related to CME propagation is obtained.

    Investigating Characteristics of Forbush Effects Recorded by the URAGAN Muon Hodoscope in the Period 2012–2017

    © 2019, Allerton Press, Inc.Abstract: Results are presented from an analysis of changes in the muon flux of cosmic rays during Forbush effects, recorded by the URAGAN muon hodoscope in the period 2012–2017 and the scintillation muon hodoscope in 2016–2017. Characteristics of the Forbush effects for this period are analyzed. The obtained characteristics of muon flux variations are compared to different parameters of the near heliosphere during the Forbush effects for the 11-year cycle of solar activity.

    Forbush Decreases During 2007–2018 According to the Muon Hodoscope URAGAN Data
    (2019) Kovylyaeva, A. A.; Astapov, I. I.; Barbashina, N. S.; Borog, V. V.; Dmitrieva, A. N.; Kompaniets, K. G.; Mishutina, Y. N.; Petrukhin, A. A.; Shutenko, V. V.; Yakovleva, E. I.; Yashin, I.

    © 2019, Pleiades Publishing, Ltd.Results of the study of variations of cosmic ray muon flux at the Earth surface during Forbush decreases registered in 2007–2018 by means of the muon hodoscope URAGAN are presented. The dynamics of the amplitude spectral index at different stages (the decrease, the minimum, and the recovery), which correspond to different phases of the influence of heliospheric disturbances on the flux of cosmic rays for the period 2012 to 2018, is considered. To investigate possible regularities in the behavior of the projection of the relative local anisotropy vector of the muon flux to the South and to the East (rS and rE) during 2007–2018, the distributions of these parameters for four phases (immediately before FD, decrease phase, minimum phase, recovery phase) were calculated.
