Monday night the sky was dark. The Sky Quality Meter was reading sqml=21.60 mpsas. Off to the east, however, silent flashes of light were intermittently lighting up the sky. This is often called "heat lightning". It is just regular lightning, but the storm clouds producing it are too far away for the sound to reach.
The following images were all obtained with a Sony A7iii and a Bower (Samyang) 35mm f/1.4 lens.

Seven minutes later, with the sky illuminated by distant lightning:
