Re: [TCML] Ball Lightning




Ball lightning terminology--we are talking about ball lightning in this thread. St. Elmo's fire is totally different. It is a corona discharge on a tall object due to the electric field from an overhead thunderstorm. I have never seen it (major life bummer) but it apparently looks about like Tesla coil streamers, but directed upward and not so active. I once heard it from the top of a flagpole--a series of pulses or a low tone varying in pitch, changing abruptly when lightning struck anywhere in the area. It was daytime, so I couldn't see a discharge. Generally speaking, if St. Elmo's fire is present in your immediate environment, you are in major trouble. I have no idea who St. Elmo was, but apparently the name was given by mariners on the old sailing ships when the corona appeared on the rigging and mast tops. It would be really cool to see it, subject of course to the caveat two sentences ago.

Can you revisit this link, the article is mixed up with another
causing a confused mess.

Here's another link, same report.

 Casual google news search on

    ball lightning

 will return a manyness of references.
