Close lightning at 36°F near Addieville, IL - March 17
A short but fruitful chase tonight! This close lightning strike shot at 10mm south of Addieville, IL occurred with surface temperatures of 36°F! You can't see it on this still here, but a shower of orange sparks was visible at the ground, where the bolt connected to power lines. I was stopped down to F7.1 here, but it wasn't quite enough to keep this from partially blowing out. Click this image for a larger verson.
Closer examination of the photo reveals three 'flashovers', places along the power lines where the lightning jumped across insulators to reach ground (click to enlarge):
Sometimes, these flashovers can start a secondary arc from the man-made current in the power line itself, creating a bright blue/turqouise explosion at the arcing point that lingers after the lightning strike is over (see the page on flashovers). The dimmer, 'streaking' orange lights in the image are sodium streetlights (their blur is due to this being a handheld shot).
