Blue auroras could be possible over Arctic regions in late April 2026 as seasonal solar geometry allows sunlight to illuminate the upper atmosphere while ground-level skies remain sufficiently dark. The phenomenon is linked to ionized nitrogen emissions that are typically too faint to detect but can be amplified under these conditions.
Auroras are expected across much of the northern United States, southern Canada, and northern Europe on December 9, 2025, following a forecasted geomagnetic disturbance caused by a coronal mass ejection (CME) produced during the December 6 M8.1 solar flare.
Extremely rare red auroras were seen over Utsjoki, Finland, on Monday and Tuesday, October 12 and 13, 2020. These natural light display, also referred to as northern lights, are normally green. However, for some reason, the solar wind on Monday excited oxygen at…
The following video was compiled from time-lapse videos recorded from the International Space Station, courtesy of the Earth Science and Remote Sensing Unit, NASA Johnson Space Centre.
The Earth's magnetic field got disturbed in response to the arrival of the September 10 halo CME caused by X1.6 solar flare. Magnetometers around the world recorded a Geomagnetic Sudden Impulse at 15:55 UTC which signaled the arrival of the CME at
Coronal mass Ejection brushed Earth's magnetic field causing G2 (Moderate) Geomagnetic Storming late on February 27, 2014. The event was associated with the R3 (Strong) Solar Flare Radio Blackout event caused by February 25th X4.9 solar flare.

This time-lapse was captured on the morning of November 11, 2013. It is suspected that two CMEs (Coronal Mass Ejections) on November 8th and 10th from two separate X-class solar flares combined to form one cloud of plasma. The interaction of this energy with
There is still only a handful of spacecraft to watch for solar and magnetic storms but the number of observatories has been growing over the last six years. Today, these spacecraft have begun to provide the first multipoint measurements to better understand space

As Earth passes through a new coronal hole high speed stream, backed by unidentified CME shock, a prolonged interval of south-pointing magnetism (southward Bz) is having a strong impact on Earth's geomagnetic field. On June 29, 2013 Planetary K-index
