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

New insight into solar wind-magnetosphere-ionosphere interactions

Editor’s Highlight—   A Sudden Commencement of a geomagnetic storm (SC) is the result of the impact on the geomagnetic field of an abrupt solar-plasma front impacting the magnetosphere. The characteristics of the SC have been described for a long time. Using a combination of data from many satellites.... more

Making the case for more sophisticated approaches to modeling radiation belts

Editor’s Highlight—   Modeling the radiation belts is often done with a simplified model for the plasma waves, those oscillations in the electric and magnetic field in near-Earth space that can scatter the relativistic (i.e., really fast) charged particles of the radiation belts, breaking their “trapped”.... more

Tracking a solar eruption through the solar system

Press Release—  Ten spacecraft, from ESA’s Venus Express to NASA’s Voyager-2, felt the effect of a solar eruption as it washed through the solar system while three other satellites watched, providing a unique perspective on this space weather event. Scientists working on ESA’s Mars Express were looking.... more

Simulations Give New View of Global Auroral Storms

Mark Zastrow, Freelance Writer

From Eos.org: Research Spotlights— New computer models capture the movement of the strongest auroral storms as they sweep across Earth at night, challenging scientists’ views of what drives them. Auroras may appear calm and gentle as they shimmer under starry skies—but that placid beauty belies how.... more

A new co-rotation electric field model

Editor’s Highlight—   This paper computes the electric field that arises as a result of the (main) magnetic field produced within the Earth and co-rotating with it. This is a difficult subject that requires dealing with the complex issue of the behavior of the Maxwell equations when changing from an.... more
