SOLAR ACTIVITY AND EARTH SEISMICITY
Solar-Terrestrial Physics, 2021 Using the results of continuous long-term observations over 50 years (including solar cycles 20–24), we study the relationship between Earth’s seismicity and solar activity.

Space weather and dangerous phenomena on the Earth: principles of great geomagnetic storms forcasting by online cosmic ray data [PDF]
Annales Geophysicae, 2005 According to NOAA space weather scales, geomagnetic storms of scales G5 (3-h index of geomagnetic activity Kp=9), G4 (Kp=8) and G3 (Kp=7) are dangerous for satellites, aircrafts, and even for technology on the ground (influence on power systems, on ...

Observation of Periodic and Transient Cosmic Ray Flux Variations by the Daejeon Neutron Monitor and the Seoul muon Detector [PDF]
Journal of Astronomy and Space Sciences, 2013 Recently, two instruments of cosmic ray are operating in South Korea. One is Seoul muon detector after October 1999 and the other is Daejeon neutron monitor (Kang et al. 2012) after October 2011.

Spectral Features of Forbush Decreases during Geomagnetic Storms
Journal of Atmospheric and Solar-Terrestrial Physics, 2023 Geomagnetic storms and Forbush decreases (FD) on Earth are primarily caused by interplanetary coronal mass ejections (ICMEs) and stream/corotating interaction regions (SIRs/CIRs) originating in the Sun, which are propagated as a low-energy plasma disturbance through the interplanetary magnetic field (IMF).

Multipoint, high time resolution galactic cosmic ray observations associated with two interplanetary coronal mass ejections [PDF]
, 2009 [1] Galactic cosmic rays (GCRs) play an important role in our understanding of the interplanetary medium (IPM). The causes of their short timescale variations, however, remain largely unexplored. In this paper, we compare high time resolution, multipoint

Investigating tensor anisotropy of cosmic rays during large-scale solar wind disturbances
Solar-Terrestrial Physics, 2017 The observable anisotropy of cosmic rays has first been decomposed into zonal harmonics and components of vector and tensor anisotropy. We examine Forbush decreases in cosmic rays that occurred in November 2001 and November 2004.

The burst of solar and geomagnetic activity in August–September 2005 [PDF]
Annales Geophysicae, 2009 During the August–September 2005 burst of solar activity, close to the current solar cycle minimum, a significant number of powerful X-ray flares were recorded, among which was the outstanding X17.0 flare of 7 September 2005. Within a relatively short

Low Latitude Lightning Activity Responses to Cosmic Ray Forbush Decreases
Geophysical Research Letters, 2020 The relation between low latitude lightning activity and Forbush decreases (FDs) of galactic cosmic rays was studied, with flash rates observed by the Lightning Image Sensor aboard the Tropical Rainfall Measuring Mission satellite and FDs selected from ...

Precursory Signs of Large Forbush Decreases
Solar Physics, 2021 The study of space-weather effects and more specifically Forbush decreases of the cosmic-ray intensity depends on space and ground measurements. Very often Forbush decreases and geomagnetic storms are accompanied by pre-increases and/or pre-decreases manifested in cosmic-ray behavior, known as precursory signs.
