Checking live activity…

Checking Thera and Turnur connections…

Live figures come straight from EVE's official ESI API in your browser: kills and jumps are the last hour, and ESI refreshes them hourly. Thera and Turnur connections come from EVE-Scout's public signature feed, mapped by their scouts and expiring on their own timers. Nothing here is cached by this site, so it is as current as those two APIs are.

Statics B Community-corroborated

From the MIT-licensed whdbx dataset, cross-checked against anoik.is: both list exactly these statics for this system. Destinations come from EVE's official wormhole data. Statics themselves are not in EVE's static data, so no official source can confirm them. Statics data: whdbx by Alexey Min, MIT licence (full notice).

What spawns in a C4

The quiet class. C4s connect to other wormholes and almost never to known space, so nothing casually stumbles through - safer to live in, and slower to move anything in or out of.

Three sites do things this one deliberately does not. Kill history, route mapping and live chain data are theirs, and they do them better.
