SpaceX sent another batch of Starlink satellites to orbit this morning from Space Launch Complex 40 at Cape Canaveral. Liftoff was at 11:07 AM EST into seasonably cool (~65ºF) and crystal blue skies over Florida.

Beautiful SKies, But Launch Bad Photography Weather

The cooler air over warmer water meant different air densities were mixing, creating perfect conditions for something I call “shimmer” but is more properly called “heat distortion.” Given that 8-9 miles is as close as almost anyone can view some launches (Starlink, especially) these are a real PITA for photographers. The stars twinkle in the night sky because of the same principles.

So, that meant taking the picture the situation allows. This is about as good a launch photo as anyone got from this launch location.

Once a rocket distorted by shimmer starts climbing, the calculus changes: skies are usually pretty clear and the acutance is through the roof.
