had some glances during the last hours and have seen 3 ringed, not mentioned in row as I did see them:
1) R: metal over red L: orange over blue V331 as far as I was able to catch
2) R: metal over black L: black over red Z848
3) R: black or perhaps darkblue ? over metal L: black all over Y445
and now I have to stop watching
thanks to all for photos, videos and navigating cam.
