Space Weather Threat to Australian Power Networks Assessed

Mark Zastrow, Freelance Writer

From 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

Comparing and optimizing the accuracy of empirical magnetic field models

Editor’s Highlight—   Improving models of the geomagnetic field is relevant to calculation of the adiabatic invariants for radiation belt studies, calculation of conjunction between satellites, calculation of mapping from the ionosphere to the magnetotail or vice versa, to name just a few applications..... 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

New study highlights ‘hidden figure’ of sun-watchers

Press Release— Few people have heard of Hisako Koyama, but the dedicated female solar observer, born in Tokyo in 1916, created one of the most important sunspot records of the past 400 years, according to new research. A new study recounting Koyama’s life finds she created detailed sunspot drawings.... more

NASA Fleet Helps Predict Space Weather

Sarah Witman, Freelance Writer

From Research Spotlights—  Using 8 years of data collected via spacecraft, scientists produce hindcasts of plasma eruptions from the Sun. These will help improve forecasts. The outermost layer of the Sun’s atmosphere is a halo of hot gases; temperatures top 1,000,000°C. This formation, called.... more

Ground-based solar monitoring and energetic particle event warning

Editor’s Highlight—   The Mauna Loa Solar Observatory (MLSO) located on a mountain top in Hawaii, USA, uses an instrument called K-Cor that creates artificial eclipse images for daily observations of the sunlight scattered by electrons in the inner solar corona. The polarized light from the solar limb.... more

Federal Space Weather Research Could Improve Hazard Preparation

Sarah Stanley, Freelance Writer

From Research Spotlights— Researchers outline the history of the U.S. government’s involvement in space weather research, from before World War II, through the Space Race, and beyond.  The Sun provides light and warmth that fuel life on Earth, but it can also generate disruptive space weather..... more

Expansion of ionospheric monitoring over Asia

Editor’s Highlight— This paper describes the exciting expansion of Global Navigation Satellite System (GNSS) monitoring across China. The Beidou Ionospheric Observation Network (BION) consists of 32 GNSS receivers across China which sample navigation signals at 0.5-5 Hz from multiple GNSS constellations,.... more
