The Nationwide Oceanic and Atmospheric Administration (NOAA) of the USA has issued a G4 extreme geomagnetic storm warning. The storm is anticipated to affect energy grids, GPS programs and radio communications. Regardless of these potential disturbances, it supplies a wonderful alternative to witness vibrant auroras at excessive latitudes, particularly in elements of Canada and the USA.
NASA astronaut Matthew Dominic, who’s presently aboard the Worldwide Area Station (ISS), shared a powerful time-lapse video of the occasion. The footage reveals the moon setting in opposition to a backdrop of dramatic purple and inexperienced auroras, earlier than dawn casts a tender blue gentle on the Soyuz spacecraft. This time-lapse was shot utilizing an Arri Zeiss 15mm lens mounted on a Nikon Z9, which was just lately transported to the Worldwide Area Station on the Cygnus cargo spacecraft.
We’re within the midst of a extreme geomagnetic storm! 🌎🧲💥

Photo voltaic flares, often known as coronal mass ejections (CMEs), are liable for these geomagnetic storms. These flares happen when unstable magnetic fields on the solar’s floor launch charged particles into area. The depth of those occasions is measured on a scale from G1 to G5, with G5 being essentially the most extreme. A G5 flare was recorded earlier this 12 months, inflicting extreme disruptions to energy grids, GPS and radio communications.
When these charged particles collide with Earth’s ambiance, they work together with atmospheric gases, creating the aurora borealis, or aurora borealis. The present geomagnetic storm is assessed as G2 and is anticipated to final till August 14.
Whereas the storm poses sure challenges, similar to potential impacts on expertise and infrastructure, it additionally supplies the chance to expertise certainly one of nature’s most awe-inspiring phenomena. The continued auroras are a surprising reminder of the dynamic interaction between Earth and photo voltaic exercise.
