Following a powerful geomagnetic storm over the weekend that caused widespread northern lights displays, there's still a possibility to see them on Monday night, though likely weaker. The forecast has 'lots of potential [and] lots of uncertainty' due to the tail end of a coronal mass ejection (CME) interacting with Earth's magnetic field.

TL;DR: Key points with love ❤️Following a powerful geomagnetic storm over the weekend that caused widespread northern lights displays, there's still a possibility to see them on Monday night, though likely weaker. The forecast has 'lots of potential [and] lots of uncertainty' due to the tail end of a coronal mass ejection (CME) interacting with Earth's magnetic field.
Trending- 1 Last May/October: Previous strong northern lights displays.
- 2 Saturday: A coronal mass ejection (CME) hit Earth, resulting in auroras.
- 3 Sunday: Northern lights show continued into daylight hours in Canada; Kp Index went as high as eight.
- 4 Early Monday: Kp Index fell to five.
- 5 Monday afternoon: Auroral oval was tipping south.
- 6 Monday night: Chance to see northern lights again.
- Beautiful displays of northern lights
- Potential for weaker displays
- Uncertainty in forecasting
- Visibility potentially hampered by smoke from forest fires
What: A possibility of seeing the northern lights (aurora borealis) on Monday night, following a powerful geomagnetic storm and widespread displays over the weekend.
When: Weekend (Saturday, Sunday), Monday night, early Monday, Monday afternoon. Previous displays in last May and last October.
Where: Canada (southwestern Ontario, Western Canada for forest fires), U.S., Airdrie, Alta.
Why: Particles from the sun carried by fast-moving solar wind, often due to a coronal mass ejection (CME), interacting with Earth's magnetic field. A CME hit Earth on Saturday.
How: Observing the Kp Index (strength of geomagnetic storm), checking if the auroral oval tips south, looking north for visibility, considering hampering factors like smoke from forest fires.
