Lightning strike yesterday evening...
http://www.swsports.org/images/Movies/strike.wmv Sorry for the little wobble - I still can't figure out how to use that stabilization thing - I know, I'm a putz. |

Any idea what it was hitting? Looked like it must have been very attractive to the lightening. There is bound to be an amount of movement beyond which stabilization will have no effect. Being caught in gusts of wind may just be more than stabilization can handle. What model camera did you get? Better yet, just post a URL to a site. -- John *H* |

If you lived in a more civilized part of the Nutmeg State, you'd know the difference between "klutz" and "putz." :) |

Were those separate strikes? They look Identical. I wondered about that myself as I'm not an expert on lightning strikes even though for about 12 years I had three tall towers in the back yard. I was only an expert on preventing damage and repairing damage I couldn't prevent. :) So I emailed one of my old friends who is a professor of meterological sciences along with the video and he replied: "It's called a secondary strike which can repeat the main strike as many as 40 times. The time delay can be variable from nanoseconds to miliseconds between the strikes. It's one of those things we were discussing the other day about "optical delusions" as the secondary strikes will occur even when the main flash is still visible - you got lucky in that one of the secondary strikes is in the millisecond category. I'll bet you anything it hit the old Fern's tower over on W. Quassett Road right? You also got lucky with the ionization flare - notice that little tiny thin flash at the start of the strike? That was the ionization trail and from the looks of it, it started at the lake." He was right which is why I aimed the camera in that direction because that tower is like a freakin' lightning magnet. Learn something new everyday although I think he mentioned it once in a lecture of his I attended - I just forgot. So it's the same as learning something new. :) |

Learn something new everyday although I think he mentioned it once in a lecture of his I attended - I just forgot. So it's the same as learning something new. *:) Simply put: Cloud-to-ground lightning (CG's) A channel of negative charge, called a step leader, will zigzag downward in roughly 50-yard segments in a forked pattern. This step leader is invisible to the human eye, and shoots to the ground in less time than it takes to blink. As it nears the ground, the negatively charged step leader is attracted to a channel of positive charge reaching up, a streamer, normally through something tall, such as a tree, house, or telephone pole. When the oppositely-charged leader and streamer connect, a powerful electrical current begins flowing. A return stroke of bright luminosity travels about 60,000 miles per second back towards the cloud. A flash consists of one or perhaps as many as 20 return strokes. We see lightning flicker when the process rapidly repeats itself several times along the same path. The actual diameter of a lightning channel is one-to two inches |

I took a direct hit on my lightnig rod on the garage the day before we went on vacation (2 weeks ago) The Mexican who had been working in the yard about ****ed his pants. He was plastered against the garage door, not moving. I was out in the yard when it hit but this was the second direct strike I have seen there in a year so I wasn't all that "shocked" It did blow the serial port on my weather station again. I guess I will have to work on that problem. It seems to be a pattern. ;-) wow , be careful something is attracting and acting like a lightning rod. if you do not have one you might want to put one up -- Boat Auctions http://sailirc.net/boats/index.php |

I'm thinking of putting it on the the top of a flagpole, as far from the house as possible. A flagpole has been on my agenda anyway. |
