Investigations of Cosmic Ray Strength in the Heliosphere Through Solar Cycles 23 and 24
Abstract: Solar wind disturbances and magnetic turbulence inside the heliosphere are affected by GCR, which effect is known as Solar Modulation. A data-driven investigation of the Galactic Cosmic Ray flux's temporal dependence over the Solar Cycle is carried out to investigate this event. Every month, we gather GCR data using a global statistical inference to ascertain how rigidity and time affect the GCR diffusion parameters. In this article, we examine their …

Review on Cosmic Radiation Effects on Spacecraft Electronics in Low Energy Transfer Range
Abstract: A review of space radiation environment from the point of its hazardous impact on spacecrafts is given. The current status of knowledge of the mass and energy spectra of the heavy fraction of the radiation environment in quiet solar daily variations and contribution of the Galactic Cosmic Rays to the average fluxes are analyzed. Further on, the main radiation effects for on-board electronics are discussed. A commonly used Linear Energy …

Heliospheric Modulation of Galactic Cosmic Rays during Solar Minimum of SC 23/24
Abstract: AbstractGalactic cosmic ray (GCR) flux at earth is modulated by the heliospheric magnetic field. Heliospheric modulation potential during grand solar minimum is observed using an open solar flux (OSF) model, with OSF source based on Sunspot number. Structure of the heliosphere controls the solar outputs and their variability, and produces changes in cosmic ray intensity. Observation was based on the data taken from Omniweb data centre for solar-interplanetary data and …

Impact of Solar Variability on the Heliosphere and Cosmic Rays Modulation with Geomagnetic Activity
Abstract: AbstractThe structure of the heliosphere and produce changes in cosmic ray intensity controls by solar variability. the observation based on data taken from Omniweb data center for solar interplanetary data and count rate of cosmic ray intensity (CRI) variation data from Oulu / Moscow neutron monitors (with cutoff rigidities Rc=0.80 GV and Rc=2.42 GV) during 1996-2018. It is observed that the sun is remarkably quiet and the strength of the …

Modulation in CRI Due to Solar-Interplanetary Causes during 1996–2018
Abstract: AbstractSolar outputs and their variations are responsible to produce modulation in cosmic ray intensity (CRI) both on short-term as well as on long–term basis. It is seen that sunspot number; 10.7 cm sun oriented radio transition, coronal mass launches (CMEs) and sunlight based flares are the causal connect to sun oriented movement (SA). In addition, coronal mass discharges are related with an assortment of interplanetary plasma and field aggravations. In …

Galactic Cosmic Rays Modulation Due to Solar-Interplanetary Activity
Abstract: AbstractThe Sun displays a multiple magnetic activities collectivity referred as solar activity. Galactic cosmic rays are subjected to heliospheric modulation under the influence of solar outputs and their variability. We observed relation between selected solar activity parameters and GCR variation. The observation based on data of Omniweb data centre for solar- interplanetary activity and monthly mean count rate of cosmic ray intensity from neutron monitor Oulu ( cutoff rigidity Rc=0.80 …
