1am night sky, occasional flashes of lightning.

On a sleepless night, I went out to our kitchen service yard and stared long and hard into the distant scenery of the dim, May night. Slowly, I found that in that very distance, a spontaneous flash of lightning could be seen on and off, illuminating the clouds at and beyond the horizon.
So I took a camera out and recorded 4:20 minutes of it.
