Aurora across all of Delaware
Delaware only sees the northern lights during major geomagnetic storms, which can strike any month but are most likely near the equinoxes (September–March). On those rare nights, the aurora appears as a faint glow low on the northern horizon rather than overhead.

Northern lights in Delaware — FAQ
Can I see the northern lights tonight in Delaware?
Unlikely: tonight's Kp is 3.3, below the Kp 7 Delaware 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 northern lights in Delaware?
Yes, on the right night. Delaware needs the planetary Kp index to reach Kp 7 for the aurora to appear low on the northern horizon. That happens during geomagnetic storms — Cosmik shows tonight's live odds above so you know before you drive out.
What Kp does Delaware need for the northern lights?
Delaware needs a Kp of about 7 for the aurora to become visible from a dark site with a clear northern horizon. That figure comes from the state's geomagnetic latitude (48.7°): the higher your geomagnetic latitude, the lower the Kp you need.
When is the best time to see the aurora in Delaware?
Look between about 10 pm and 2 am local time, on a clear, moonless night, from a spot with no light pollution and an open view to the north. The season peaks September–March, and geomagnetic storms are most frequent near the equinoxes. Cosmik tracks the live Kp so you can catch the exact night it spikes.
Which direction should I look for the aurora in Delaware?
North. From Delaware 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.
