Hello,

I would like to know if any of you have tried to see if variations in the H-field could be detected if you move a magnet in front of a ferrite antenna.
It would probably need to be moved/waved a bit fast because of the low pass filtering in the preamps to see anything.

The reason why I ask is because I want to see if I can make a system to detect magnets being brought into a fitting room.
Shoplifters use strong magnets to take of security labels. If you can detect their magnets, you can catch them in the act.

I already have a system that can detect a magnet at about 30cm, but I want to extend this to about 80-100cm.
The (leaked) pictures of the system blue preamp look a lot like what I had in mind to make, but in my case with low pass filtering and probably a lot of gain.

Milan.

Greetings all!

Just a curiosity more than anything..

Last night we had quite a wicked little storm (along with others in the area) move through my community..  There was easily a few flashes every minute (or more) for about a half-hour at least.  I know for sure there were storm cells besides the one over us, causing all sorts of lightning at the same time.

Curiously, not a single stroke was detected by ANY station, mine included (though it may have been too close).

I did observe that all the lightning appeared to be inter, and intra cloud and very little, if any cloud to ground.

I wonder if that makes any difference?  I know that storms earlier in the day in my area were quite accurately picked-up, so it's not an issue of lack of coverage..


Ideas, thoughts?   Makes me wonder if we are missing a lot more strikes than we realize...

Cheers

For the last 13 years, I have used exclusively Mac computers and don't intend to change back to Windows or Unix for the foreseeable future. If I purchase a System Blue to become a station in the Haut Var in France (Tourtour), which is a lightning hot spot, with my house being hit by lightning twice in 12 years, are there versions of the software to work with Mac computers? I would very much prefer not to install virtualisation software such as Parallels or Fusion + Windows or Boot Camp, given the problems this has caused in the past, when I installed Parallels then Fusion plus Windows 8 to try and run medical practice management software, only available in a Windows version. Boot Camp, Apple's own version of a Windows operation partition, caused different but as many problems, particularly with running daily back ups. 

As a newbie to Lightning detection, any advice would be most welcome.

PS Is the final price of the System Blue kit announced yet?

Greetings all!

I have a quick question in calculating the length of the e-field antenna.. (in order to enter it into the station details section)..

I want to put a few loops at the end of the copper wire antenna.. would the antenna length be whatever the length of the wire rod was BEFORE twisting the loops (longer), or just the length AFTER creating the loops (shorter)..

My gut feeling is that the loops are still considered part of the antenna length, even though they aren't straight.

Thanks everyone

Hi,

At this moment i have the experience that the created alerts not come consistently.
I have made in the config.php the next settings:

Good afternoon fellow "Blitzortunger's"!

I am in the process of commissioning a newly built system "Red" lightning detector, and have a question in regards to that.

I already have a user ID number and account.  I have tried repeatedly to enter my 24 digit system ID hex number (without dashes) into the appropriate field.  However, when I click "OK", the field simply clears, and the system remains unregistered.

Is there something I am missing here?  I would think that is all that is involved.  Perhaps new system registration has been temporarily suspended?

Thanks in advance, and I look forward to participating,

Cheers from Canada

Sometimes it is possible to check the accuracy og the system.

The roof is copper and acts as a lightning rod, so nothing happened

Today, I spend some time to watch die Google map for BO.

There are some (active) stations far far away from other (>1000km) :

 993 - Maui, Hawaii - United States / Hawaii
 935 - Atalaya  and 665 - Cúcuta - Colombia
1267 - Sint Eustatius - Netherlands Antilles
 913 - Rio de Janeiro, Copacabana and 939 - Fundão - Brazil
1305 - Farm Tivoli - Namibia
1332 - Wolmanansstad
1352 - Pretoria - South Africa
987 - Armavir - Russian Federation
1365 - Doha - Qatar
1307 - Turar and 1357 - Almaty - Kazakhstan
1113 - Bangkok - Thailand
1303 - Hong Kong - China
844 - Rockingham - Australia
973 - Perth - Australia
966 - Darwin, Alawa and 915 - Darwin - Humpty Doo - Australia

The northernmost station is 184 - Inari, Ivalo - Finland, the southernmost is 1325 - Dunedin - New Zealand.

Whats' about the station in the Antarctic ?

Hope, I didn't forget one

We need some stations in Alaska, Canada, Argentina, Chile, Russian Union, Japan ...
