Lightning strikes heard, but did not appear on map. - WØTDH - 2014-07-23
We heard three/four strikes near us, but no indication of those on map.
( During last two T.S that passed through today )
Intensity of strikes too low or no rcvr site near enough to our location?

Between the DC region and Florida, there is indeed a "gap" without stations. Typically, to detect strikes in NC would probably require the participation of (at the closest) some of the DC region stations, Florida stations, and Kentucky stations. So lower-intensity strikes might get missed, anyway, due to the distance...and if enough of the surrounding stations are in interference mode due to storms in their immediate vicinity, stations even farther away would need to do the detecting. It's a situation higher density of stations will help quite a bit.
It's also possible that the strikes were cloud-to-cloud, which the Blitzortung system (like most lightning detection networks) filters out.

Hello, I'm a new user in this forum
I live in Tromsø in northern part of Norway. Normaly we do not have much lightning here. But last year we had a few days. And this year it has been lighting strikes many times through the summer. We have had especially hot weather thats not normal for this region, so that is the reason for all those lightining strikes.
I first discovered this site when a newspaper posted a picture of the map when the bad weather was coming up from the south in the country. And I have visited this site regualary since. It seems that none of the strikes in the northern part of norway is detected at all. I know there is no detectors here, but it seems that they have a pretty good range? I see detectors in northern Finnland detecting strikes in Germany and Poland...
Will the high mountains in my region interfere with the detections from far away? I see the closest detector is in Trondheim (in middle of Norway) and the ones in northern Finland.
Would it help for the rest of the northern part of Scandinavia if I got an detector here?
Is there special requriements besides power for the electronics and internetconnection that is required for this to work?

Hello,
Lightnings in your area are not detected because the coverage is not important enough. You can have some explanations there: http://www.lightningmaps.org/extra/coverage?lang=en&ratio=&dist%5B150%5D=1&dist%5B500%5D=1&dist%5B2000%5D=1&bouser
Every participant is welcome but maybe that in your region we will need more than only one detector...
There is no particular needs more than a power supply and internet. Avoid installation near noisy electric equipments.

That's because YOU were not participating, or you had seen much more.
There should actually just one or two more stations in your area at a reasonable coverage

"Important Enough" might simply be a translation artifact... not to put words in Delande's mouth, but perhaps he meant "dense"... not enough stations...

Yes Mike that's right.
Sorry, I do my best

if you're bored, get Google translate, enter something in English, translate it to, say German... Then translate the German back to English. Repeat it several times. The final result is liable to start a war... .

Those of us who have enough difficulty speaking one language are just glad most of this board is in English!
