A fast‑moving stream of plasma from a yawning coronal hole is barreling toward Earth, and forecasters at NOAA’s Space Weather Prediction Center (SWPC) have issued a G2 (moderate) geomagnetic‑storm watch for the night of 25 June 2025. If the solar‑wind blast couples efficiently with our planet’s magnetic field, auroras could surge as far south as Colorado, New York…

A burst of high‑speed solar wind from a giant coronal‑hole on the Sun is slamming Earth’s magnetic field this week, prompting NOAA to issue a G2‑level geomagnetic‑storm watch and raising the odds that the aurora borealis will spill far beyond its usual haunts—potentially as far south as Illinois, Ohio and New York on the night of 24–25 June 2025.…

Microwave radiometry is a passive remote sensing technique that measures naturally emitted thermal radiation in the microwave portion (0.3–300 GHz) of the electromagnetic spectrum. In essence, a microwave radiometer detects weak microwave energy from Earth’s surface and atmosphere and expresses it as a brightness temperature, the equivalent blackbody temperature of the emitting source. Unlike optical…

A New Era of Weather & Climate Satellites The period 2025–2033 is witnessing an unprecedented boom in satellite constellations dedicated to weather forecasting and climate monitoring. Around the globe, space agencies and private companies are deploying hundreds of new satellites to observe Earth’s atmosphere, oceans, and environment with greater fidelity and frequency than ever before.…

Introduction to Weather Satellites Weather satellites are spacecraft orbiting Earth that continually observe atmospheric conditions from above. They serve as “eyes in the sky” for meteorologists, providing a global view of weather systems that ground observers alone could never achieve. By capturing images and data on clouds, storms, temperature, and more, weather satellites supply crucial…

Space weather refers to variations in the space environment between the Sun and Earth that can affect technological systems both in orbit and on the ground swpc.noaa.gov. It is generated by solar phenomena—particularly solar flares, coronal mass ejections (CMEs), high-speed solar wind streams, and solar energetic particle events—that release bursts of radiation and charged particles…
