Time between strikes

[Jon1980]

Is there a color chart somewhere that shows the time line of a strike? I see that they change color and am not seeing anything to show me how long it has been since the strike happened. Certain customers shut us down due to lightning and we have to wait 30 min from the last strike within eye sight. I found this and would like to use it more often but i need to be able to prove that we are in the clear. Any help would be appreciated.

Uhm, unless I'm missing something, the answer is right before your eyes.

You didn't say what you were that 'gets shutdown'.... but the "30 minutes since last visible strike" is an excellent 'rule of safety' ! Assuming I now also see an horizon to horizon clear sky. I would not depend on Blitzortung or any other network's data to be a 100% guarantee that an "anvil crawler" starting 50 miles away wouldn't decide to earth at my location!

I think some things need to be voiced very clearly and strongly before anyone attempts to use Blitzortung for determining when it might be time to do something relative to the last time of a strike. See the following statement that can be found on the Blitzortun.org "Contact" webpage (http://www.blitzortung.org/Webpages/inde...=en&page=7):

That was pretty clear.

That said, it is also my impression so far that BO is better giving positive indications than negative.
Meaning if it indicate a strike, then the probability is high that there was one. Maybe cloud-cloud, but a lightning anyway.
If it does not indicate a strike there may well have been one, or many.

There will also be a very long way to go to claim indication of every strike. Even the expensive commercial services will not give you that. Maybe we'll get there before there is a man on Mars, maybe not.
