Exploring How Space Weather Can Damage Power Grids

Michael Hapgood, Editor, Space Weather

Editors' Highlight— A new model of geomagnetically induced currents revisits how space weather damaged a New Zealand grid transformer in 2001, and shows how much worse it could be in a space weather superstorm. A key topic in space weather research is how to model the geomagnetically electric currents.... more

Space Weather: Exploiting Meteorology’s Toolkit

Michael Hapgood, Editor, Space Weather

Editors' Highlight— Space weather forecasting is benefiting, and can benefit much further, from concepts and tools already developed by the global meteorological community. Tools previously developed to assess and improve the value of terrestrial weather forecasts are now being used to advance space.... more

A Cost-Loss Approach to Solar Wind Forecasting

Commentary— This commentary concerns recent work on solar wind forecasting by Owens and Riley (2017). The approach taken makes effective use of tools commonly used in terrestrial weather—notably, via use of a simple model—generation of an “ensemble” forecast, and application of a “cost-loss” analysis.... more

Preserving a 45-Year Record of Sunspots

Emily Underwood, Freelance Writer

Research Spotlight— Maps reveal how the Sun’s magnetic field evolves through solar cycles. In 1964, the late solar researcher Patrick McIntosh launched an ambitious effort to track sunspots—relatively cool, dark blotches on the Sun caused by disturbances in the star’s magnetic field. He traced sunspots.... more

Comparing the Accuracy of Geomagnetic Field Models

Delores J. Knipp, Editor-in-Chief, Space Weather

Editors' Highlight—  Improved accuracy and optimization of models could benefit many applications. Improving models of the geomagnetic field is important to radiation belt studies, determining when satellites are on the same magnetic field line, and mapping from the ionosphere to the magnetotail or.... more

A Survey of Solar Radio Burst Statistics

Delores J. Knipp, Editor-in-Chief, Space Weather

Research Spotlight— National solar radio archive records have substantial missing data potentially affecting the ability to benchmark extreme solar events. Noting the threats from large radio bursts to Global Navigation Satellite System (GNSS) receivers and other radio technology systems, Giersch et.... more

Space Weather Threat to Australian Power Networks Assessed

Mark Zastrow, Freelance Writer

From Eos.org: Research Spotlights— Power companies should be cautious during severe solar storms to maintain the integrity of Australia’s power grid, a new study finds. When the Sun unleashes its powerful storms, some of the most vulnerable pieces of human infrastructure are power grids. The mass of.... more

Imaging the Sun’s Atmosphere

Delores J. Knipp, Editor-in-Chief, Space Weather

Editor’s Highlight— The technique of heliospheric imaging could be valuable for future space weather operations. Heliospheric imaging is a technique developed to look at the Sun’s extended atmosphere, rather than the Sun itself. The Sun’s tenuous atmosphere extends well beyond Earth’s orbit. The accompanying.... more

Verification of space weather forecasts

Editor’s Highlight—   This paper shows thorough validation of our current probabilistic capabilities concerning space weather forecasting. The authors present initial forecast verification from two types of probabilistic forecasts of space weather activity: predictions of geomagnetic Kp and predictions.... more

Measuring radiation at the International Space Station

Editor’s Highlight—   This paper offers some very practical insight into how radiation and radiation dose is measured at the International Space Station (ISS). The authors provide simultaneous, long-term estimates of radiation dose external to the ISS for four source categories: (i) galactic cosmic.... more
