Geomagnetic effects on cosmic ray propagation under different conditions for Buenos Aires and Marambio, Argentina [PDF]

, 2014
The geomagnetic field (Bgeo) sets a lower cutoff rigidity (Rc) to the entry of cosmic particles to Earth which depends on the geomagnetic activity. From numerical simulations of the trajectory of a proton using different models for Bgeo (performed with ...

Ionospheric Response to the May 11, 2024, Geomagnetic Superstorm over Ecuador [PDF]

arXiv
This study investigates the impact of the G5 geomagnetic storm on Total Electron Content (TEC) derived from the Global Positioning System (GPS) in Gal\'apagos, Ecuador (geographic latitude 0.1807{\deg} S, longitude 78.4678{\deg} W) during May 10-13, 2024. Using vertical TEC (VTEC) data from a single pseudorandom noise (PRN) code, along with the average

Observations of Ion Density and Temperature around the International Space Station During two Geomagnetic Storms [PDF]

, 2018
The International Space Station (ISS) is a low Earth orbit research facility and host to an international crew. Geomagnetic storms cause changes in the Earth’s magnetic field and affect the ion density and temperature in the ionosphere which could pose a

No Major Solar Flares but the Largest Geomagnetic Storm in the Present Solar Cycle

, 2015
A severe geomagnetic storm, and the largest in solar cycle 24, occurred on 17–18 March 2015 without significant precursor Xor M-type solar flares.

Intense Geomagnetic Storms during Solar Cycles 23-25 [PDF]

arXiv
Intense geomagnetic storms are characterized by a minimum value of the Dst index at or below -100 nT. It is well known that these storms are caused by the southward magnetic fields in coronal mass ejections (CMEs) and corotating interaction regions (CIRs). While CIR storms are confined to Dst values at or above -150 nT, CME storms can reach Dst -500 nT
