Hello,
Dealing with raw data I wondered how accurately the whole system (especially concerning Europe) is working.
When downloading raw data the coordinates are given with an accuracy of five or six decimal places. Calculating worst case scenario (a stroke being detected on the equator) the maximum deviation would be calculated as following:
5 decimal places: +- 55,5 m
6 decimal places: +- 5,5 cm
(The stroke was detected in a circle with +- x metres round the given position.)

I do not think the network is able to calculate positions of strokes with this accuracy, can it?
Secondly I wondered about the deviation parameter "mds" descibed as giving the maximum deviation in nanoseconds. Am I right this value refers to the stroke´s timestamp given at the beginning of each line? But in what way does this affect the position of the stroke?
(Could it be the radius of the circle is calculated by multiplying the deviation "mds" with c = 299 792 458 m/s?)

best regards
PothThom

and thanks for your time...

Hallo zusammen

seit der Webseitenumstellung habe ich Probleme ...
Menüs gehen nicht mehr bzw. die Unterseiten sind nicht aufrufbar .
Gesetzte Favoriten sind auch nicht mehr verfügbar....

Hello,

When I surf blitzortung with my tablet, I'm always redirected to the dynamic map and I don't like it

It would be nice to have a little cookie which remembers the choice I've made between the mobile or desktop version.

Regards

Just yet I've read a newsletter from The Royal Netherlands Meteorological Institute (KNMI) about 3D lightning analysis.

Happy reading.

Hello,

I have made some (maybe) interesting maps animation from Blitzortung.org data during year 2015 over Europe.

First is timelapse of 90 minute history images with 10 minute step. Look at summer fronts above continent and winter "electrified" cyclones in Mediterranean area.

Second is GIF animation of monthly merged lightning strikes into European map.

Hello Group I'm new to the group, my Name is Bill and I live in Yuba City, CA, USA. I have always had a big interest in storms and lightning and have made several detectors, just simple pulse detectors with a beeper and flashing LED. Well I have had it on the back burner to build a detector that would give me azimuth too. I was on the web page from Holland I thing for the Lightning Radar LR detector. Well I noticed it was no longer being used due the the passing of the guy who developed it, rest his sole. 

Sense I had the parts I made a PCB and put it together and Have been playing with it trying to learn from it. To my surprise I can pick up lightning a lot father away than I thought I could. From California I can see storms from the east coast of the US. My setup is  a pair of opamps and 2 fairrite loop antennas both about 200mm long. I have the antennas shielded they are connect to the opamp board in a water tight box right next to the antennas and I have cat 5 cable running to the ham shack right below it. Antennas are running NS and EW and both are tuned to 10 khz. 

OK here is where my question comes in. right now I'm connected to a digital Oscope and I set the trigger high enough so only a lightning pulse sweeps it. But I noticed that most of the time one trace is out of phase with the other one 180 degrees. I took care to make sure both antennas are connected the same ie ground and signal. Is this normal that the NS and EW signals would be out of phase 108 degrees or do I need to swap the leads on one antenna? 

I plan on connecting it to my sound card and play with it on Spectrum Lab but want to make sure it is connected right to begin with. Every once in awhile I get a signal that looks to be in phase. I hope to soon to setup the system used here using TOA, but for now I want to learn as much as I can and maybe write some software to use this setup as a portable system I can use while RVing. 

Thanks and I hope this post is OK here on this Forum, if not delete and let me know, I want to stay in good terms with the group. Also Have been watching the Biltzortung real time maps and I have to say Wow! what a great system.

There seems to be a problem viewing the new website using Chrome or Safari on iPad. The pop up menus off the main menu bar are not visible, only the Login button works.

Other than that, the new website looks very nice, and System Blue is looking good

Hi collegues,
I am planning to give my fellow HAMs in our area (North-East Netherlands) a presentation on Blitzortung.
I would like to give the people who started this fantastic system a place in my story. However on the website I can not find data on historical facts of the organisation like when the initiative started (2003?) and by whom and where ?
Maybe some of you had the same idea and actually showed the fun of tracking thunderstorms this way. Would you be willing to share your presentation material with me ?

Hallo zusammen,

habe vor über einem Jahr die Teile bestellt, bin aber seit dem nicht dazu gekommen, mich mit mit einem Lötkolben bewaffnet auf das Projekt zu stürzen.

PCB 12 Ver. 3c und PCB 10 Ver. 4 

War das Set  a+b+E:
-Controller board PCB 10.4, GlobalTop PA6H GPS module, SMA connector, and a network connector
-H-Field Amplifier board PCB 12.3c, 4xMCP6S91, 2xMCP6292, 2xLMH664, and a programmed ATmega8 microcontroller
-two 20cm ferrite rod antennas

Evtl. war auch die etwas spärliche Dokumentation, was man noch an Bauteilen braucht und wie man weiter vorgeht, dran schuld das ich da noch nicht dran gegangen bin. ;-)

Habt Ihr evtl. eine Bauteilliste für mich, was ich noch für die oben aufgeführten Teile brauche, um sie fertig zu bestücken und eine Anleitung wie ich sie in betrieb nehme?

Würde mich sehr über Eure Antworten freuen.

Grüße,
Oliver

The map pages seem to have changed recently and it is no longer possible to zoom in on my Android phone. This makes the map more or less useless
