"Corotating Interaction Regions (CIRs)", "Interaction Regions (IRs)" and "Stream Interaction Regions (SIRs)", which term should be used?
Bruce T. Tsurutani, Rajkumar Hajra, Gurbax S. Lakhina
We discuss the early history of quasiperiodic ~27-day recurrent geomagnetic activity starting with Maunder (1904, 1905), Chree (1913) and Bartels (1932, 1934), and the Bartels term…
The April 2023 SYM-H = -233 nT Geomagnetic Storm: A Classical Event
Rajkumar Hajra, Bruce Tsatnam Tsurutani, Quanming Lu +8
The 23-24 April 2023 double-peak (SYM-H intensities of -179 and -233 nT) intense geomagnetic storm was caused by interplanetary magnetic field southward component Bs associated wit…
Review of the August 1972 and March 1989 Space Weather Events: Can We Learn Anything New From Them?
Bruce T. Tsurutani, Abhijit Sen, Rajkumar Hajra +3
Updated summaries of the August 1972 and March 1989 space weather events have been constructed. The features of these two events are compared to the Carrington 1859 event and a few…
Interplanetary Causes and Impacts of the 2024 May Superstorm on the Geosphere: An Overview
Rajkumar Hajra, Bruce Tsatnam Tsurutani, Gurbax Singh Lakhina +2
The recent superstorm of 2024 May 10-11 is the second largest geomagnetic storm in the space age and the only one that has simultaneous interplanetary data (there were no interplan…
Geomagnetically Induced Currents (GICs) during Strong Geomagnetic Activity (Storms, Substorms, and Magnetic Pulsations) on 23-24 April 2023
Irina Despirak, Pavel Setsko, Andris Lubchich +5
We analyzed intense geomagnetically induced currents (GICs) recorded during a complex space weather event observed on 23-24 April 2023. Two geomagnetic storms characterized by SYM/…
NORAD Tracking of the February 2022 Starlink Satellites (and the Possible Immediate Loss of 32 Satellites)
Fernando L. Guarnieri, Bruce T. Tsurutani, Rajkumar Hajra +2
The North American Aerospace Defense Command (NORAD) tracking of the SpaceX Starlink satellite launch on February 03, 2022 is reviewed. Of the 49 Starlink satellites released into…
Comments on "New Insights from the 2003 Halloween Storm into the Colaba 1600 nT Magnetic Depression during the 1859 Carrington Storm" by S. Ohtani (2022)
Bruce T. Tsurutani, Gurbax S. Lakhina, Rajkumar Hajra
The Colaba, India ~-1600 nT magnetic spike caused by an interplanetary sheath magnetic field inducing a "dayside R1-field aligned current wedge" during the Carrington magnetic stor…
The Possible Cause of the 40 SpaceX Starlink Satellite Losses in February 2022: Prompt Penetrating Electric Fields and the Dayside Equatorial and Midlatitude Ionospheric Convective Uplift
Bruce T. Tsurutani, James Green, Rajkumar Hajra
On ~1613 UT, 3 February 2022 SpaceX launched 49 Starlink satellites from Cape Kennedy, Florida into ~210 km altitude orbits where they were to receive subsequent boosts. We assume…
Space Plasma Physics: A Review
Bruce T. Tsurutani, Gary P. Zank, Veerle J. Sterken +13
Owing to the ever-present solar wind, our vast solar system is full of plasmas. The turbulent solar wind, together with sporadic solar eruptions, introduces various space plasma pr…
Cometary Plasma Science -- A White Paper in response to the Voyage 2050 Call by the European Space Agency
Charlotte Götz, Herber Gunell, Martin Volwerk +27
Comets hold the key to the understanding of our solar system, its formation and its evolution, and to the fundamental plasma processes at work both in it and beyond it. A comet nuc…
Solar flares observed by Rosetta at comet 67P
N. J. T. Edberg, F. L. Johansson, A. I. Eriksson +6
Context. The Rosetta spacecraft made continuous measurements of the coma of comet 67P/ Churyumov-Gerasimenko (67P) for more than two years. The plasma in the coma appeared very dyn…
Plasma Density Structures at Comet 67P/Churyumov-Gerasimenko
I. A. D. Engelhardt, A. I. Eriksson, G. Stenberg Wieser +7
We present Rosetta RPC case study from four events at various radial distance, phase angle and local time from autumn 2015, just after perihelion of comet 67P/Churyumov-Gerasimenko…
