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).

Pulsar in a C4 B Community-corroborated

Pulsar systems are very powerful when utilized correctly. They provide large improvements to shield hitpoints and capacitor recharge time. They also greatly increase ship signature radii, enabling the effective use of much larger weapons than would be available in ordinary systems. Armor ships will suffer a resistance debuff, and should be used carefully or not at all. And finally, as a partial countermeasure to the capacitor recharge bonus (especially against capital ships), Energy Neutralizers and Noferatus are also greatly strengthened.

Effect C1C2C3C4C5C6
Shield Capacity +30%+44%+58%+72%+86%+100%
Armor Resists -15%-22%-29%-36%-43%-50%

Signature Radius +30%+44%+58%+72%+86%+100%
NOS & Neut Drain Amount +30%+44%+58%+72%+86%+100%

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.
