'Cannibal' Solar Storm Could Paint Auroras Above 18 US States This Labor Day

'Cannibal' solar storm could paint auroras above 18 US states this Labor Day

Space weather experts warn that a "strong" geomagnetic storm will rock Earth on Sept. 1-2, potentially lighting the skies with vibrant auroras across large parts of North America. The disturbance is being triggered by a rare, cannibalistic ejection from the sun.

Cannibal explosion from Sun to hit Earth today. Power grids, satellites on alert

This rare and intense solar event began on August 30, when sunspot region AR 4199 unleashed a long-duration M2.7-class solar flare.

Solar plasma strike expected to induce major geomagnetic storm today

New Delhi: On 30 August, at 20:02 UTC, the SIDC Sunspot Group 617 or NOAA Active Region 4199 erupted in a long-duration M2.7 flare, the second-highest category of solar flares. This resulted in a spectacular full-halo coronal mass ejection (CME), where magnetised plasma from the Sun is hurled outwards into interplanetary space. On encountering planets with a geomagnetic field, such as the Earth, this material from the Sun induces geomagnetic sto…

Solar Aurora Possible Mon Night: Flares and CME likely to cause G3 (strong) geomagnetic storm

At Providence, solar aurora may be visible overnight Mon into Tue, although fairly unlikely. Aurora is unusual at latitudes this far south, but it typically happens a few times every year. Weather at Providence during the potential aurora will be partly cloudy with about 50% cloud cover, temperature about 60°F and near-zero chance of rain. The aurora is caused by a pair of solar flares on Aug 30, a relatively small magnitude M1.3 event at 1159UT…

Long-duration M2.7 solar flare launches Earth-directed CME, impact expected late on September 1

A long-duration solar flare measuring M2.7 at its peak erupted at 20:02 UTC on August 30, 2025. The eruption produced an asymmetric full halo coronal mass ejection (CME), with impact expected late…
