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
