What it takes to see the aurora borealis (northern lights) from North Bay
Aurora visibility is set by your geomagnetic latitude — your position relative to Earth's magnetic pole, not the geographic one. North Bay sits at 54.7° geomagnetic. The auroral oval hovers near 66° in quiet conditions and expands toward the equator as geomagnetic storms strengthen: roughly 2° per step of the Kp index. For North Bay that means a moderate-to-strong storm (Kp 5.1+) pushes the oval close enough to see glow on the northern horizon.
How to actually catch it
- Get away from city lights with a clear view of the northern horizon — light pollution is the #1 killer of borderline displays.
- Best window: 22:00–02:00 local time; best seasons: around the equinoxes, and dark winter months at high latitudes.
- Your camera sees more than your eyes: a 5-10s phone night-mode exposure reveals green/red glow invisible to the naked eye.

FAQ
Can I see the northern lights tonight in North Bay?
Unlikely: tonight's Kp is 2, below the Kp 5.1 North Bay needs. A free Cosmik alert emails you the moment the forecast reaches it. Updated every 30 minutes from NOAA SWPC data.
Can you see the aurora from North Bay?
Yes, when geomagnetic activity is strong enough. North Bay sits at geomagnetic latitude 54.7°, which means the aurora becomes visible on the northern horizon at roughly Kp 5.1 — during moderate to strong storms.
What Kp index does North Bay need for aurora?
About Kp 5.1. The auroral oval sits near 66° geomagnetic latitude in quiet conditions and pushes roughly 2° toward the equator with each Kp step; North Bay's geomagnetic latitude is 54.7°. You don't need the oval directly overhead — NOAA notes the aurora can be seen on the horizon from up to 1000 km away, but that reach grows with the storm: this figure credits none of it near the oval, where low-Kp aurora is faint and low, and up to 2.5 Kp at mid-latitudes, where storm aurora is tall and bright.
Which direction should I look for the aurora in North Bay?
North. From North Bay the auroral oval lies toward the north magnetic pole, so the aurora appears low on the northern horizon first. Pick a spot with an open northward view, away from city lights — your phone's night mode picks up glow your eyes miss.
When is the best time to see the aurora?
Around local midnight (22:00–02:00), on dark clear nights away from city lights, and statistically around the equinoxes (March/April and September/October). Solar maximum — happening now — delivers the most storms.
