Best seen full screen as the bolt is extensive. The charge goes from the two points where the difference in electrical potential charge is greatest. Sometimes that is ground to cloud. Sometimes cloud to ground. The last possibility is cloud to cloud. This of course is the latter. When I think of lighting, it’s cloud to ground but I see many of each type in the limited storm chasing I do. I way prefer cloud to cloud from a safety standpoint lol. Hopefully there isn’t cloud to Raptor…..
I tend to see these cattle in this hollow when storms come through as I watch storms from this hill top often. The road up there isn’t a mud problem as others are. The type of soil is better drained sandy material. I don’t like to drive on ground that will rut and work rain storms lol. Those cows though… I think there is some instinct that says clear out of the rest of the square mile pasture and congregate there during a storm. I’m not sure of the instinct that drives them here. I’m not even sure of the instinct that drives me here lolol.
So lightning heats up the air to around 50,000 degrees F. That’s about 5 times the temperature of the surface of the sun. When the differences in charges between the clouds in this case overcame the insulative ability of the air, a flash happens. Quickly… Like the close to the speed of light fast.
Chasing LIghtning is not for the faint at heart. Being in a vehicle “reduces” your exposure. It’s also possible for the vehicle to be struck. This can destroy the vehicles wiring or it’s computer. You also don’t want to be touching metal when that goes down lolol. I’ve been very close to bolts before. This one was REACHING out my direction lolol. It’s miles long.
I was driving up in Montana where my son and I watched a bolt hit the dirt 30 feet off the road on the drivers side. It hit in front of us so we had a clear view of it. I can still see the outline. The truck was all closed up so the sound was muffled. I’ve heard some pretty loud bolts but with a window open… a close bolt is going to leave some “ringing” in my ears lolol.
I usually work scenes like this with 2 cameras sitting on the cars passenger window on clamp tripods. Using Lightning Triggers allow you to set your camera to click with the bolt. My Sony Mirrorless respond within a few milli-seconds to the initial start of the flash. I usually use about 1/4second or longer time exposure which you adjust to the brightest part of the image. (expose the highlights properly). If you set the ISO too high, you will have the bolts too bright which tends to grow them larger than they are. This is about as perfect an exposure as you can get for as dark as it was for this scene. 📸
