🌌 Tonight in Grand Canyon: A Moonless Masterpiece

Date: June 14–15, 2026 | Sky Quality: Bortle 2 (pristine natural darkness)
Moon: Waning Crescent (<2% illuminated, below horizon all night — moon set before sunset, moon rise after 4am)
Viewing Quality Index: 100/100 — perfect conditions

⏱ Hour-by-Hour Evolution

The weather cooperates beautifully, improving as the night deepens:

• 9 PM (MST): 21°C, clouds at 14% (a few high wisps, no issue), light wind ~3.5 m/s, fog 0%. Starts clear and mild.
• 10 PM: 19.5°C, clouds drop to 12% — the sky cleans up. Wind eases to 3.2 m/s.
• 11 PM: 18.5°C, only 10% cloud cover. Thermals are settling, air becoming still.
• Midnight: 17.8°C, 8% clouds — transparency is excellent. Wind negligible at 2.9 m/s.
• 1 AM: 17.2°C, 7% clouds — the best hour. Near moonless, zero fog, 16 km visibility.

Trend: Clear early, getting progressively better toward 1 AM. No precipitation, no fog, no aurora interference. The night can only improve.

🔭 What to See

✨ Only one bright planet visible: Venus (-3.9 mag) — it sets early after sunset, so catch it low in the west during twilight. The real show is deep-sky.

💫 Top 3 Messier picks for tonight's moonless sky:

Also don't miss M6 & M7 (the Butterfly and Ptolemy clusters) in Scorpius, and M31 (Andromeda Galaxy) — it's just rising after midnight, but its 3.4 mag core is an easy naked-eye target from Grand Canyon's dark skies.

No ISS passes tonight and no meteor shower activity — but the Milky Way will be a river of starlight overhead by 11 PM.

🗺 Pro Tip

With Bortle 2 and a nearly invisible moon, bring binoculars (or your telescope) and scan the Scorpius–Sagittarius region after 10 PM. The Lagoon Nebula (M8) and Trifid Nebula (M20) are just south of M7 and are visible as soft glows even without filters at this site.

Set up early, let your eyes adapt, and enjoy a night that starts good and only gets better. 🌟
