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).

Cataclysmic Variable in a C4 B Community-corroborated

Cataclysmic Variable systems are an interesting paradox. On the one hand, they enormously increase the strength of remote repair modules, and the capacitor volume of the ships using them. (And while they also slow capacitor recharge times, the larger increase in volume results in increased stability.) On the other hand, they also greatly reduce the strength of local repair modules, and remote cap transmitters. The result is a system type which encourages group play with either spidertanked ships or heavy logistics support, but forces the use of locally cap-stable logistics ships and discourages capital warfare.

The C4 column is the one that applies here. Effect ladders stated identically by two independent sources: the EVE University wiki (rev 230274), which cites CCP's Hyperion dev blog for the August 2014 rebalance that set these numbers, and the anoik.is dataset. 32 of 33 rows agree.

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.
