Ursids in Mexico City

The Ursids meteor shower peaks from Mexico City around Dec 22, with up to 10 meteors per hour under ideal conditions. In 2026 a half moon will wash out fainter meteors, and from Mexico City the radiant in Ursa Minor climbs to 28° above the north horizon around 05:45. Local best viewing window: 04:45–05:45 CST on the peak night, about 1.0 hours of astronomical darkness. Scaled to that altitude, the 10/hour headline figure works out to roughly 5 meteors an hour from Mexico City under a genuinely dark sky. The radiant stays low from Mexico City, so expect fewer meteors but longer, shallower trails near the horizon. Tonight: overcast throughout, so expect nothing visible.
