During periods of heightened solar activity, the aurora borealis could be visible from ten U.S. states on clear, dark nights; check local aurora forecasts and cloud-free skies for the best viewing chances.
A 94-day observation of solar active region NOAA 13664 by Solar Orbiter and SDO captured its evolving magnetic field, revealing the Sun's strongest geomagnetic storms in over two decades and causing auroras visible as far south as Switzerland along with disruptions to satellites and railway signaling; the study, published in Astronomy & Astrophysics, marks a major advance in understanding space weather.
A groundbreaking collaboration between the ground-based DKIST telescope and the space-based Solar Orbiter has provided new insights into the Sun's activity, including the discovery of tiny structures called 'campfires' and detailed observations of the Sun's magnetic fields, advancing our understanding of solar phenomena and their impact on Earth.
NOAA has issued G1-G2 watches for January 3-4 due to expected CMEs from solar activity, which may cause minor to moderate geomagnetic storms, affecting HF radio and navigation signals.
NASA's Parker Solar Probe captured unprecedented close-up images of the Sun's magnetic activity during its 22nd flyby, revealing new details about magnetic 'tadpoles', the tearing of the heliospheric current sheet, and the formation of magnetic in/out pairs, advancing our understanding of solar phenomena.
NASA's Parker Solar Probe captured detailed images of solar material doing a 'U-turn' after eruptions, revealing how the sun recycles its magnetic energy and material, which could improve space weather forecasting.
NOAA has issued a G3 warning due to effects from a coronal hole high-speed stream, impacting radio communications and navigation, with conditions expected to persist into Wednesday evening, December 3, 2025.
A powerful X1.9 solar flare from sunspot AR4299 caused radio blackouts in Australia and Southeast Asia, with further solar activity expected from the larger, more complex sunspot AR4294, potentially leading to additional flares and minor geomagnetic storms in the coming days.
NOAA has issued a G2 (Moderate) geomagnetic storm watch for December 3-4 due to a coronal mass ejection associated with an X1.9 solar flare, which may impact radio communications and navigation systems.
India's Aditya-L1 solar mission is poised to observe the Sun during its maximum activity cycle in 2026, a period marked by increased solar storms and coronal mass ejections (CMEs). The mission aims to study these phenomena to better understand solar behavior and improve space weather forecasting, which is crucial for protecting Earth's infrastructure and satellites. Aditya-L1's unique instrumentation allows continuous observation of the Sun's corona, providing valuable data during this intense solar period.
The Northern Lights have been visible across the U.S. and parts of the world due to a G4 geomagnetic storm caused by solar eruptions, creating spectacular displays in the sky, including in England, China, Germany, and various U.S. states, with the storm being one of the strongest in decades.
NOAA has issued geomagnetic storm watches from November 11 to 13 due to coronal mass ejections (CMEs) impacting Earth, with storm levels ranging from minor to moderate, and ongoing analysis to refine forecasts.
The northern lights will be visible in the Austin area tonight due to increased solar activity and favorable weather conditions, making it a rare opportunity to see the Aurora Borealis far from its usual polar regions.
A powerful geomagnetic storm caused the northern lights to be visible across many US states, with forecasters predicting continued auroral activity due to multiple coronal mass ejections from the sun, potentially leading to more spectacular displays and G4 severe storm conditions.
The article provides tips for photographing the northern lights, emphasizing checking aurora forecasts, choosing dark locations, planning compositions, using appropriate camera gear, and adjusting settings for optimal shots, especially during peak solar activity periods.
