Sorry if this is posted somewhere already.  A forum search for "dashed" and/or "green" is not providing an answer.

What are the straight, green dashed lines showing up on the page  https://www.blitzortung.org/en/live_lightning_maps.php  ?

They are often intercontinental but don't seem to show up with every strike.
