Hello alltogether,

blitzortung is really a great project. I am already on the list, if a station in Dortmund, germany is needed

My question is: Does somebody use a blitzortung-map in grafana? I managed to embed the interactive map as html via iframe:
   

The embedded map is static and does not resize, if the browser window size is changed. In this case scrollbars are shown in the interactive map due to defining a static height and width:
   

Did somebody already try to embed a reziable map? For my case, the interactive map is not necessary. This small map is great:

  2019-09-22 22_36_53-Integrate into your own website __ LightningMaps.org.png (Size: 4.72 KB / Downloads: 44)

I would be great if I could define
1. the central point of the map (e.g. Dortmund = 51.514468, 7.465147)
2. the width e.g in kilometers or as coordinates of how much from the map is always shown, (200 km width or "show the map until 51.336534, 9.499416")
regardless of how small or big the map is.

Any hint would be helpful.

Have a great day

Hey there!

Recently I've noticed that lightning strikes in northern Sweden has been absent. I had a full blown storm above my head with 30-40+ strikes that didn't show on the map.

Previously it has been spot on all the time, but the last two storms were not present apart from one strike out of *many*. Even the giant ones doesn't register even though I think some of them might have raised hairs a hundred miles away.

Is this due to faltering coverage or something else?

I have had a station for a few years as user: opadavis. Today I cannot sign in. I have requested a new password but this does not work. I have had to generate another name and email address in order for me to ask for help.

My day started with getting a new modem that has not yet assigned an IP address to the lightning reciever. I was able to find it (http://192.168.0.219) for the older Cisco DPC3848V, but cannot find it in the new Hitron 2250.

Please help.

Problem: When searching on this forum, we cannot search for gps or any of the six 3-character words at the top of our status pages.

Reason: The default minimum search term in MySQL is four characters.

Solution: A very simple change to a configuration file can change it from to four to three.
This article at https://www.electrictoolbox.com/mysql-fu...ord-length tells how.  

Quote:Change the full text index minimum word length with MySQL

The MySQL full text index by default only indexes words which are 4 characters or longer, which means on a blog like mine if you search for "PHP" nothing will be returned. This post shows how to change minimum word length in MySQL so words or 3 characters (or even 2 if you want) can be indexed as well.

Edit the MySQL configuration file my.cnf which is usually located on a *nix box at /etc/my.cnf or /etc/mysql/my.cnf and add the following line under the [mysqld] section to change the default to 3:

Code:

ft_min_word_len = 3

If the ft_min_word_len value is already in the file then change the number to the minimum length required.

After making this change the MySQL server must be restarted for it to take effect. It is not possible to change the size with a set query (e.g. "SET ft_min_word_len = 3" which will result in the error "#1193 - Unknown system variable 'ft_min_word_len'").

Now that the minimum word length has changed, and new or updated records will use the new minimum word length, but existing records will not be affected. To rebuild the full text index on a column for an example table called my_table, run this query:

Code:

REPAIR TABLE my_table QUICK;

I have seen comments by some people who have suggested that on large tables it may be faster to drop the index and create it again depending on the size, and also that the repairing it may mean the query cache is not flushed whereas dropping and re-indexing will solve this.
Note however that if you drop the index and then re-create it you may get SQL query errors on your website. As always it is advisable to test this sort of thing out on a development server configured in the same way as a production server before doing it to the production server to ensure you don't have any issues.

Hallo,

ich habe mal eine Frage in die "Blitzgemeinde".

Ich möchte die Rohdaten pro Tag auslesen und dann pro Tag die Entfernung von dem am kürzesten entferntesten Blitz und wenn die Entfernung z.B. unter 15 km von meiner Station (2624) liegt dann auch noch zusätzlich die Menge der Blitze feststellen. Beides  möchte ich in merine Wettertabellen (Excel) einbaiuen.

Nun stoße ich hier auf mehre Probleme...

Wenn ich beim Auslesen der Daten



24 h (von 0:00- 23:55) dann erhalte ich überhaut keine Ergebnisse! (Vieleicht ist die Datenmenge zu hoch?)

Hat da jemand vielleicht eine Antwort?

Das zweite Problem ist, mit den Daten die ich dann Empfange, kann ich erstmal so richtig nichts anfangen...  

time,lat,lon,alt,pol,mds,mcg
1567947600566532546,45.393374,12.88165,0,0,14263,68
1567947600566528007,45.390739,12.87448,0,0,10801,120
1567947600566539991,45.418641,12.858451,0,0,4087,221
1567947602015536261,45.350632,12.912416,0,0,5344,108

Was bedeuten diese Zahlen?

die Überschriften

time --> Was ist das für eine Zeit??
lat
Ion ---> sind das die Georgrafischen Koordinaten ? (Länge, Breite) ???
alt --> ?
pol ---> ??
mds ---> ???
mcg ---> ????

Fragen über Fragen....

Kann mir jemand helfen?

As you can see the Greek stations appears 2 times on the list in this link.

Maybe the admins have to check it!
Have a nice day!

 Dear All

I am new to this community and posting for the first time in this forum. Can't wait to complete the assembly of my System Blue kit and begin contributing to this global network.

However I haven't been able to find any information related to the best practice of antenna placement and installation location (Let me know if it's my fault).

Is there any best practice or installation position to avoid for both the E-field and H-field antennas? 

The Antenna Documentation does say "It should be placed high and far away from electrical installations" but can community members please share how high and how far you positioned your antenna? 

By the way, I live in a very dense urban neighbourhood (Hong Kong) and I would appreciate if you could share your experience, if any, installing your hardware in such undesirable settings.

May the fields be with you.

Our blitzortung network is picking up lightning around the eyewall of the hurricane. As we all know, lightning in hurricanes is uncommon, except for in intense hurricanes. The storm just hit 180 mph sustained winds and over 220 mph gusts. This is scary situation for the Bahamas. All unprotected living beings will suffer the wrath of this dangerous hurricane. I hope for the best for them all. 
I live in Jupiter, Florida, which is about 100 miles west of the Bahamas. We still have the possibility of a hit, even though the models have it turning north, the warning cone still has us in our area. 
I’m going to have to take down my electrical probe from the roof, but I will be keeping the magnetic field up.

Brand new System Blue just received. I parted the PCB boards and filed the nubs when L104 fell off. C605, right next to L104, has a cracked joint and tombstoned up when I touched it.

How should I proceed? I don't mind trying to rework board but all I have is lead-based solder. Is this indicative of faulty board which will continue to give me trouble?

Hi All,

I would like to know what kind of CAT5 cable I should use between the H-Field pre-amplifier board and the mainboard. Is it a crossover cable or straight through cable?

Thanks

Best regards

David
