Solar Wind Sets the Magnetosphere Ringing

Alan Rodger, Editor, JGR: Space Physics

Editor’s Highlight— A combination of data from satellites and ground-based instruments gives new insight into solar wind-magnetosphere-ionosphere interactions. A Sudden Commencement of a geomagnetic storm is the result of the impact on the geomagnetic field of an abrupt solar-plasma front impacting.... more

Analyzing a 3-D kinetic simulation of a vortex-induced reconnection event

Editor’s Highlight—   This paper presents an analysis of a 3D fully-kinetic simulation of Kelvin-Helmholz vortices along Earth’s magnetopause. The results of the simulation are compared to observations from NASA's Magnetospheric Multiscale (MMS) mission. The authors present evidence of secondary, turbulent.... more

Analysis of pulsations observed during a solar flare

Editor’s Highlight—   Solar flare emission at X-ray and extreme ultraviolet energies cause substantial enhancements in the electron concentration in Earth’s lower ionosphere (about 60-90 km altitude). Flares often show quasi-period emission (QPPs) with periods ranging minutes to tens of minutes. This.... more

Is There a Greenhouse Effect in the Ionosphere, Too? Likely Not

Mark Zastrow, Freelance Writer

Editor’s Highlight—A mechanism of mid-latitude noontime foE long-term variations inferred from European observations The study of long-term trends and in long-term variations in thermospheric and ionospheric parameters are currently very popular, and conclusions of these studies differ substantially..... more

How Earth’s Outer Radiation Belts Lose Their Electrons

Emily Underwood, Freelance Writer

From Eos.org: Research Spotlights— A new analysis of three space storms reveals the mechanisms of particle loss from the Van Allen belts. The Van Allen belts are massive, donut-shaped rings of radiation that encircle Earth, extending up to 58,000 kilometers into space. Held in place by Earth’s magnetic.... more

MMS mission data on the Earth’s dayside magnetopause

Editor’s Highlight—   Using data collection by the Magnetospheric Multiscale (MMS) mission spacecraft in the high-resolution mode, this paper presents the first detailed account of magnetic reconnection observed at the front side of the Earth’s magnetosphere on length scales down to the electron scale..... more

Description of substorm cycle in Mercury’s magnetosphere

Editor’s Highlight— This study uses observations from the MESSENGER (MErcury Surface, Space ENvironment, GEochemistry, and Ranging) spacecraft of Mercury’s (southern) magnetospheric lobe. The authors analyze tail loading and unloading phases in a dataset based on 1000 passes. These phases are viewed.... more

Iron ions discovered in the Earth’s magnetosphere

Editor’s Highlight—   Apparently the Earth's magnetosphere is iron-fortified, just like your breakfast cereal. Not only does this paper present the discovery of singly-charged iron ions but also tests three possible sources for these ions, concluding that they originate from the Earth’s ionosphere..... more
