As 2024 draws to a close, stargazers are in for a treat. A G3 geomagnetic storm is set to light up the skies with the northern lights. This celestial show will begin in early January, peaking on 31 December night and continuing into 1 January morning.
The Sun has really stepped up over the past few days, with frequent solar flares including a strong X-class event! A selection of these flares produced Earth-directed eruptions, expected to trigger a strong geomagnetic storm (bringing aurora) on the 31st! #spaceweather pic.twitter.com/oSiBZWAM4h

Causes of this spectacular phenomenon
The aurora borealis occurs when solar particles meet Earth’s magnetic field. These particles, released by solar flares, energise the atmosphere. On 29 December, a coronal mass ejection (CME) was released. This solar event is responsible for the upcoming auroral display.
Three X-class solar flares also erupted on 29 December, enhancing the spectacle. Though these CMEs won’t directly strike Earth, they will energise particles enough to produce vivid auroras.
Viewing locations and times
NOAA predicts the best viewing times will be between 4 a.m. and 7 a.m. EST on 31 December. The auroras could stretch as far south as:
Parts of Europe will also witness this display. Clear skies and dark locations are ideal for the best experience.
What is a geomagnetic storm?
Geomagnetic storms occur when solar activity disrupts Earth’s magnetic field. These storms can impact satellites, navigation systems, and power grids. Fortunately, Earth’s magnetosphere protects humans from harm while creating stunning auroras.

The G3-level storm is linked to Solar Cycle 25's high activity. This cycle has brought frequent northern light displays throughout 2024.
Tips for viewing the aurora
Find a dark location away from artificial lights. Look north with a clear view of the horizon. Use night mode on your camera to capture vibrant colours.
This rare New Year’s Eve event promises to be unforgettable. For skywatchers, it’s a dazzling farewell to 2024.
