Satellite Watching in Provo

Best Viewing Season

Summer and fall (June–October)

Weather Conditions

High altitude means thinner atmosphere and better seeing. Winter storms can bring clouds but are interspersed with crystal-clear spells. Summer is generally excellent.

Light Pollution

Provo has a Bortle class of 7 (suburban skies — ISS and bright satellites visible). The Mountain West region averages about 150 clear nights per year.

Launch Visibility

Not visible from the Mountain West.

Parts of Nevada and Utah have reported seeing exhaust plumes from Vandenberg launches during twilight, though this is uncommon.

Viewing Tips for Provo

The high elevation is a huge advantage — less atmosphere means brighter satellites. Central Idaho, rural Utah, and western Colorado have world-class dark skies. Natural Bridges and Great Basin are certified International Dark Sky Parks.

Best Time to Watch

Check for passes during the first 2 hours after sunset or before sunrise. This is when satellites catch sunlight against a dark sky.

What to Look For

Satellites look like steady, bright stars moving smoothly across the sky. They don't blink like airplanes.
