A thunder storm

We did get an inch-and-a-half of rain and the landscape is greener.  During the storm, I tried out the video feature of the Canon 60Da because we were getting quite a lightshow.  The camera was running at 59.94 fps.  The CMOS sensor reads out from top to bottom,  so it records only partial frames of short duration events like  lightning flashes.

Here are 3 consecutive frames:

Apparently there are several flashes recorded.  A snippet of the movie is on YouTube.
