When I select the Realtime Maps tab the window that comes up shows detectors and vectors but there no longer are any MAPS in the background.

Is there a fix for this?

Tried to search this forum with all the relevant keywords but could not find this to have been discussed. Sorry in advance if I'm mistaken.

I am writing software to fetch the recent strikes as per documentation, and while everything else seems to work perfectly, the "time" parameter in the URL seems to be ignored.

/Data/Protected/last_strikes.php?time=1778840631155816319&number=30000&west=10&east=40&north=70&south=50&sig=0

done at time 1778840931155816319 (i.e. the request limit is 5 min earlier) results in response containing (as last record, there were 1188 records, so the "number" parameter did not limit anything either)

{"time":1778827480863817500,"lat":60.535376,"lon":33.547539,"alt":0,"pol":0,"mds":14367,"mcg":242,"status":0,"region":1}

Here are the times again with a fixed width font and a space separating seconds from nanoseconds
REQUEST:           1778840631 155816319
REQUEST DONE AT:   1778840931 155816319
RESPONSE:          1778827480 863817500

So the record is almost 4 hours old. I can easily filter those out, but just wondering whether there is a bug or I just do not understand something here. Likely the latter.

Also, the documentation states that the default value of the "time" is "current time stamp", which cannot possibly be true? Wouldn't that filter out all the strikes automatically (and by default!)?

Anyway, being new to this project and community, I have to say that I am deeply impressed by the quality of everything. Especially I love the no-nonsense diagnostic page of the station!]]>

I'm Adrien Revel, technical director at AKER. I'm writing on behalf of artist Marie-Luce Nadal to request access to Blitzortung's historical lightning data for a non-commercial sound art installation.

The project is called "Skin Of the Sky" and premieres June 6, 2026 at the Église Saint-Laurent in Paris during Nuit Blanche. The concept: members of the public call a phone number and confide a wish to the sky. Their voice messages are then spatialized inside the church, triggered and positioned by real lightning strike coordinates. Using an azimuthal equidistant projection centered on the church, each strike maps to a physical direction in the nave. Storms over Sweden send voices from the north, storms over Brazil from the south-west, and so on.

What we find beautiful is the kinship between our projects: Blitzortung is built by a worldwide community of volunteers mapping the electrical activity of the sky; Skin Of the Sky collects anonymous voice messages, the emotional activity of people looking up. Both are participatory, open, and built on collective contribution.

What we need: access to a few days of global archived strike data for offline playback. We do not need real-time access.

Regarding the external project criteria:

• Non-commercial: public artwork, free admission, co-produced with the City of Paris
  
• Original use: lightning data drives spatial sound, not a map or weather tool
  
• Freely accessible to the public
  
• Blitzortung.org credited as data partner in all signage and communications
  
• No redistribution of raw data, used only within the physical installation
  
  

We'd be glad to share documentation and footage with the community afterward.

And if anyone here would like to participate, the phone line is open now: call +33 1 59 58 00 99 and confide a wish to the sky. Your voice could end up traveling through the church, carried by one of the lightning strikes you helped detect.

Thanks for reading, and thanks for the remarkable network you've all built together.

I looked at a project on github.com that uses WebSocket. I was able to get it running and receive thunderstorm marker data on the map.

To avoid overhead, I saved the history in localStorage, meaning new data is stored temporarily while the delay occurs.

Can I use WebSocket in an app?

Naturally, I'm specifying blitzortung.org to make it clear.

My goal is weather, precipitation, and markers. I know this is just for fun and not 100% accurate.]]>

My station 1365 used to be located in Doha, Qatar, but I moved country a few years ago to Cyprus, and have resurrected the system and after giving the amp board a bit of TLC it appears to be working again on the test bench.

However, I have noticed that LightningMaps is continuing to show the station located in Qatar and not in its new location of Cyprus, Paphos, depending on which part of the site you are on.

I can't see any options to resync or force any update, so I assume that this will need to be done by admins.

Can someone help?

Thanks,

I'm in the process of adding lightning data to a weather site / app that I'm creating at  weathercastpro.com/

This is non-commercial, free to use. 

how do I request access to use the blitzortung lightning strike data on my radar feature?

I beleive I need credentials for non-commercial projects under CC-BY-SA 4.0 license.

The website is created purely for public benefit and educational purposes — it is free to use, contains no paid access, and does not generate any profit. Its goal is to help people better understand weather conditions, especially severe weather and thunderstorms.
I am currently working on a storm and precipitation map, and I am looking for a reliable way to visualize real lightning activity. Unfortunately, I do not have the technical possibility to build and operate my own Blitzortung detector, and there are no other free and trustworthy sources of live lightning data available.
Therefore, I would like to kindly ask whether it would be possible to grant limited access to lightning data for this non-profit project, or to advise me on any acceptable way to use Blitzortung data in a public, educational context.

My name is Krzysztof. I am a software developer and a student at the Silesian University of Technology. For several years, I have been developing a system for detecting lightning strikes in long video recordings, as a tool to facilitate the work of storm chasers, researchers and software developers. This project has become the subject of my engineering thesis. As part of my master's thesis, which I am currently working on, I am creating a system that involves continuous detection of lightning strikes on video streams from cameras, which will allow for the approximation of the location of a lightning strike.

I wanted to ask if it is possible to obtain raw detection coordinates with timestamps in order to compare these results in my master's thesis.

I saw that on the Blitzortung website, you can only access raw data if you are a contributor, so unfortunately, I do not have access to this data (I was considering joining the project, but there are already detectors in my area, so I don't know if it makes sense). Unfortunately, the historical data I can obtain on LightningMaps is also in the form of a map (without the coordinates and timestamps I need).

Thank you in advance, and I look forward to your response or suggestions on where I could obtain such data.

Best regards, Krzysztof]]>

Ich möchte trotzdem einmal mitteilen, dass sich auf der VectorMap-Seite ein Tippfehler bei dem PopUp-Feld für die einzelnen Stationen ein Tippfehler eingeschlichen hat.

Bei "Statistik für Benutzer: xxx" wurde das 'z' vergessen.
