Analysis of 42 years of Cosmic Ray Measurements by the Neutron Monitor at Lomnický stít Observatory
Imre Kisvárdai, Filip Štempel, Lukáš Randuška +4
The correlation and physical interconnection between space weather indices and cosmic ray flux has been well-established with extensive literature on the topic. Our investigation i…
Comparing 1-year GUMICS-4 simulations of the Terrestrial Magnetosphere with Cluster Measurements
Gabor Facsko, David Sibeck, Ilja Honkonen +18
We compare the predictions of the GUMICS4 global magnetohydrodynamic model for the interaction of the solar wind with the Earth's magnetosphere with Cluster~SC3 measurements for…
Sub-ion scale Compressive Turbulence in the Solar wind: MMS spacecraft potential observations
Owen Wyn Roberts, Rumi Nakamura, Klaus Torkar +9
Compressive plasma turbulence is investigated at sub-ion scales in the solar wind using both the Fast Plasma Investigation (FPI) instrument on the Magnetospheric MultiScale mission…
The Source Regions of Whistlers
Dávid Koronczay, János Lichtenberger, Mark A. Clilverd +7
We present a new method for identifying the source regions of lightning generated whistlers observed at a fixed location. In addition to the spatial distribution of causative light…
VLF transmitters as tools for monitoring the plasmasphere
David Koronczay, Janos Lichtenberger, Lilla Juhasz +2
Continuous burst mode VLF measurements were recorded on the RBSP/Van Allen Probes satellites and are analyzed to detect pulses from the Russian Alpha (RSDN-20) ground-based navigat…
Midlatitude ionospheric F2-layer response to eruptive solar events-caused geomagnetic disturbances over Hungary during the maximum of the solar cycle 24: a case study
K. A. Berényi, V. Barta, Á. Kis
In our study we analyze and compare the response and behavior of the ionospheric F2 and of the sporadic E-layer during three strong (i.e., Dst <-100nT) individual geomagnetic storm…
