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

The appearance of plasma bubbles at mid latitudes during severe storms

Editor’s Highlight—   Based on data analysis of Total Electron Content estimated from Global Navigation Satellites and Defense Meteorological Satellite Program spacecraft ion density measurements, this paper reports the occurrence of plasma bubbles (depletions) in an anomalously high middle-latitude.... more

The application of heliospheric imaging to space weather operations

Editor’s Highlight—   This paper provides a timely assessment of the value of heliospheric imaging observations in the context of space weather operations with a clear apparent aim of advocating for a deep-space mission for operational space weather prediction. The authors review a cross-section of.... more

Researchers uncover 200-year-old sunspot drawings in Maine

Blog—  When the summer of 1816 was abnormally cold, with severe frosts in June and snow in July, Reverend Jonathan Fisher did what he always did: He documented it in his journal. Fisher, a Harvard-educated minister in the small coastal town of Blue Hill, Maine, used his own phonetic shorthand to record.... more

Testing Models of Near-Space Electrical Currents

Leah Crane, Freelance Writer

From Research Spotlights— Modeling Earth’s near-space environment and its electrical currents is challenging. A new study compares how four different models stack up against observations. High in Earth’s atmosphere, electrical currents called Birkeland currents flow along the planet’s magnetic.... more

Improving the prediction of geoelectric fields caused by magnetic storms

Editor’s Highlight—   The use of 3D induction models for the modeling of geoelectric field is a young field. Most current models still use 1D models but there is a need to compare with 3D models and begin to understand the differences and significance of 3D induction effects. This paper presents an.... more

Impact of Space Weather on the Satellite Industry

Editor’s Highlight—   Today’s society is ever more dependent on satellites but space weather can cause malfunctions or total breakdowns. This paper offers a bridge between the heavy science aspects of space weather and sometimes ephemeral societal impacts studies. It could be useful for both technological.... more

Ground Surveys Reveal Space Weather Risk to Spain's Power Grid

Mark Zastrow, Freelance Writer

From Research Spotlights— A survey of bedrock conductivity across Spain improves predictions of how vulnerable the nation's power grid is to solar storms. When you think of regions that are vulnerable to solar storms, the first places that probably come to mind are at high latitudes, like.... more
