Star wolves 3: Validol help

[Mars_Alator]

I'm playing star wolves 3 for my first time and I'm having trouble locating Validol after recieving the letter from Aylon.

The letter says his last known location was in a casio in Sunnie. I don't know if I'm being completly stupid but I can't find a system called Sunnie and have not came across any casios in the systems I have been in.

Can someone please enlighten me as to where I should be going?

Ok I figured it out the system is Solncevka, if you continue to Moscovy you get the chance to chose to find Validol before continuing with the mission Viper sets you.

you need a radar that can detect ships 400 clicks aways (4 square blocks) in this mission
i bought it at charon
to make it eaisier *click "v" on keyboard two times when you're at grid menu (press tab at game)
