  Data Access
Posted by: John.Sacrey - 2015-11-06, 15:32 - Forum: General Discussion - Replies (28)

Hi Folks,

I have been seeing several members requesting access to the network data without having a participating station.  I hope the following information will save the developers some time in answering emails on this subject, so they can continue developing System Blue unimpeded. 

Access to the data is granted after you have a completed and registered station that is sending data to the network. The data is not to be used for commercial purposes and/or monetary gain. To my knowledge, there aren't any exceptions to this. Any exceptions would have to come from Egon and/or Tobi.

Respectfully,

John Sacrey

  resonance frequency
Posted by: JuR - 2015-11-06, 15:17 - Forum: Hardware, Software, Lightning Physics - Replies (7)

Hello, 
i am trying to understand the functionality of B- and E-field antennas, but there is one thing that i dont understand.
Why do the magnetic antennas that are presented in the project description have a resonance frequency? The loops behave like  inductors, but there are no capacitors, so there shouldnt be a resonant circuit?
Greetings,
Julian

  RED-Controller nach Stromausfall nicht mehr lauffähig
Posted by: BerndKie - 2015-10-31, 18:38 - Forum: Non-English - Replies (1)

Guten Tag,

gestern Nacht hatten wir während eines entfernten Gewitters zwei Mal einen kurzen Stromausfall (je ca. 5 sec.).
Wie ich am nächsten Morgen feststellen mußte funktionierte mein RED-Controller (RED_board 10.4; fw7.4, contr.) seitdem nicht mehr, denn Blitzortung.org meldet 0 (NULL) Signale seit 31.10.2015, 00:49 h, siehe:
http://www.blitzortung.org/Webpages/inde...t_order=de .
Trotzdem steht meine Station (1025) mit dem Status "ONLINE" in der Liste. Mein WLAN-Router weißt den RED-Controller mit "OFFLINE" aus.
Ich versuchte trotzdem mit dem Webbrowser und der korrekten IP einen Connect zum RED, aber wie zu erwarten vergebens.

Sodann betätigte ich sowohl am Controller als auch am Amplifier die Resettaster, löste und schloss alle Kabelverbindungen. Die kleinen LEDs auf beiden Platinen leuchten bzw, blinken wie gewohnt. Es fällt aber negativ auf, daß das Display dunkel bleibt und keinerlei Anzeige macht. Alles änderte nichts daran, daß der Controller nicht mehr sendet.

Bis zu diesem Ausfall arbeitete das System hervorragend und war in der Stationsrangliste von Spanien in der Effectivity M&L meistens auf Platz zwei oder eins.
Gibt es noch eine Hoffnung, den Controller wiederzubeleben?
Muß ich den Controller und/oder Amplifier als nicht reparabel abschreiben oder hat jemand von den Experten noch einen Rettungsvorschlag?

Gerne erwarte ich hilfreiche Vorschläge.
Es grüßt

  Interessante Geschichte zu Blitzeinschlägen?
Posted by: BotterSt - 2015-10-23, 13:47 - Forum: Non-English - No Replies

Hallo Forum,

ich bin von einer Redakteurin (Fernsehen) wegen der Blitzortung kontaktiert worden. Sie möchte einen Beitrag über Blitzeinschläge drehen, über das Blitzortungsprojekt soll es dabei auch (kurz) gehen. Sie sucht nun aber nach einem "Aufhänger" für die Story, ihr schwebt eine Erfahrung mit Blitzeinschlägen vor - sie hatte jemanden, bei dem der Blitz im Lauf von einigen Jahren mehrfach eingeschlagen hat, dieser ist aber leider abgesprungen.

Nun meine Frage: hat jemand von Euch eine solche oder ähnliche Geschichte, die er/sie mit dem Fernsehpublikum teilen möchte? Ich kann die Verbindung zur Redakteurin herstellen.

"Fernsehen" heißt hier öffentlich rechtlich, und sachlich, vielleicht mit einem kleinen bisschen Schock.

Vielen Dank für Eure Aufmerksamkeit,

Stefan

  Ortungswinkel - locating angle
Posted by: hans.mayer - 2015-10-02, 17:10 - Forum: Website, Maps and Applications - Replies (2)

dear all, 

what is "ortungswinkel" ( locating angle ) ? 
today i noticed a stroke at  02.10.2015 16:12:34.826867174 UTC
location of the lightning was Lat/Lon: -4.405123 / 18.224421 
my possition is: 16 17' 1" East 48 8' 57" North --> JN88dd45at

www.lightningmaps.org tells me that Ortungswinkel is: 189 degress 
accidentally i noticed i get a different value if i calculate the angle. 
on my linux box i have a command line tool called "qth" which tells me 178 degrees.
if i use google earth the result is 177.55 deg which is as rounded value the same as qth's result.
but both are quite different from the result of lightningmaps.org

on other hand i can't believe that ightningmaps.org does bad mathematics.
so my question: what is this value for called in german "ortungswinkel" ? 

kind regards 
hans

  NeB Q: Will nearby FM Radio Cell towers cause problems
Posted by: br1ght - 2015-09-18, 20:20 - Forum: Hardware, Software, Lightning Physics - Replies (2)

HI All,
I am considering purchasing a Blue (once available) and setting up at my house. My concern is that I have a cluster of several large (120-170 m tall) towers within a 0.3 km of my property. One or more at broadcasting at 93.1 MHz. another lower tower is a cell that may be using HSPA+ technology and eventually LTE... the cluster is due west of my property the direction which most of our Tstorms approach from. 

My question is, will the 'wall of towers' interfere with receiving approaching storms? I realize their broadcast bandwidths are well above the VLF of lighting but will their close proximity limit the receiver's reach to the west  Huh  TIA

  Infrasound
Posted by: Bonzo - 2015-09-15, 16:57 - Forum: Hardware, Software, Lightning Physics - Replies (10)

I am wondering whether it would be useful to add an infrasound detector to the Blitzortung System.

Obviously it could register the sound of thunder of a local thunderstorm and add some time information. At least for regions with high station density.

But moreover, there seems to be a correlation of infrasound and the appearance of sprites. [1]

So, to register pulse profiles of the EM wave in conjunction with the infrasound profiles would add a fundamental research experiment to the system.

The sensor could be realized by means of so-called microbarometers. That has to be evaluated. Also the effect of interferers like wind turbines en stuff.

This is just an idea, not a proposal.

What do you think, it this interesting? Feasable? Desirable? Are there people out there that have the skills (and interest) to add according algorithms to the existing software?

Or is that completely out of interest for this project?

BTW: I am connected with the LOFAR radiotelescope [2] where some stations are also equipped with infrasound detectors as a part of the infrasound array of the Dutch meteorology institute KNMI.

cheers
