🌌 Tonight at the Grand Canyon: Patience Pays Off

Bortle 2 skies + a razor-thin Moon + clouds that finally clear = a rewarding late-night session.

Hour-by-hour breakdown

There's a beautiful trend here: clouds steadily erode from 64% at 9 PM down to 40% by 1 AM — a classic canyon burn-off pattern. Meanwhile, temperatures slide from 21°C to ~18.7°C (bring a light jacket), winds stay flatter than a pancake at ~3 m/s, and visibility holds at a crisp 16 km throughout. Precipitation is negligible (5–6%).

🌙 The Moon & Planets

• Waning Crescent at only 10% illumination — practically invisible. The sky stays moonless until it creeps back above the horizon in the pre-dawn hours, giving you hours of pristine darkness.
• Saturn (mag 0.58) is the sole planet in view, transiting at 04:04 AM — its rings will be razor-sharp through a scope during that 1–4 AM window. Worth staying up for!

🎯 Targets for the Clear Window (01:00 onward)

• M22 (globular, mag 5.1) — a dense summer showpiece, low but juicy.
• M13 & M5 — the Great Hercules cluster and its rival; with Bortle 2 darkness, these will resolve into countless stellar pinpricks.
• M7 & M6 — two gorgeous open clusters nestled in the Milky Way's core.
• M31 & M33 — Andromeda and Triangulum climbing higher for galaxy hunters.

Verdict: The first half of the night is a bust, but 1 AM onward is a goldmine — moonless, transparent, steady air, and Saturn nearing its best. Set up early, let the canyon skies shed their clouds, and be ready when the switch flips. Clear skies! ✨
