We've just been treated to a great light show. I guess it's common near the coasts, but it's fairly rare here in the cornfields, we call it heat lightening. The sky lights up like fireworks, but it is completely silent. The cloud cover and the lightening have to be just right. I tried to take a video, but it's too dark to see much. Mrs WD and I have been on the back porch in our rockers, sipping wine and watching the show. It's a beautiful sight. What a gift.

From Wikipedia:
"The actual phenomenon commonly called heat lightning is simply cloud-to-ground lightning that occurs very far away, with thunder that dissipates before it reaches the observer.[2] At night, it is possible to see the flashes of lightning from very far distances, up to 100 miles (160 kilometres), but the sound does not carry that far."
