I uploaded my logs there and it's one i discovered first so should be it!Thank you! I looked through the EDSM data and this might actually be it, body C6 has large gap in it's rings. The only thing that worries me is that on the screenshots the ring looks like it is illuminated by something blue and the system has only yellow and red stars. Still Byeia Eurk ZC-S c5-9 is worth checking anyway
