…Checking tonight's sky…
The next three nights
Geomagnetic activity (Kp) forecast for the selected town's dark hours. Kp runs 0–9; how much a town needs depends on its magnetic latitude. New to this? What the Kp index means, in plain words → Nights tagged “outlook” use NOAA’s 27-day outlook where the 3-day forecast doesn’t reach — whole-day values, so treat them as rougher estimates.
What Talkeetna needs for a show
Whether aurora reaches a town is mostly a matter of magnetic latitude — distance from the magnetic pole, not the geographic one. Talkeetna sits at magnetic latitude 62.9°, which puts it in the Kp 3 band: when the forecast Kp for the dark hours reaches about 3, the oval's southern edge reaches Talkeetna and displays can appear low on the northern horizon. At Kp 5 or better, expect the band overhead at times. The same law draws the band on the homepage globe: the oval's edge at magnetic latitude 69 − 3×Kp.
| Magnetic latitude | 62.9° |
|---|---|
| Kp needed (horizon show) | About 3 |
| Kp for a strong overhead show | About 5+ |
| Coordinates | 62.3239°N, 150.1094°W · Southcentral |
Kp is only one of four ingredients in the live call above: cloud cover over the dark hours, the town's actual darkness window, and moonlight all count too. A Kp 5 night under solid cloud is still a no — which is why the verdict, not the index, leads this page.
Talkeetna’s aurora season
Talkeetna has a real off-season: from about Apr 15 to Aug 27 (135 nights) the sun never dips 18° below the horizon, so it never gets truly dark and aurora can't be seen even when it's active. Outside that stretch, 230 nights in 2027 get a true-dark window.
| Month (2027) | True darkness | Typical dark window, mid-month |
|---|---|---|
| January | Every night | 12 hr 8 min |
| February | Every night | 9 hr 58 min |
| March | Every night | 7 hr 1 min |

True darkness = the sun below −18° (end of astronomical twilight), computed with the standard NOAA solar algorithm for Talkeetna’s coordinates. The live call at the top of this page uses tonight's actual window, not these averages.
