Are you talking about the Earth Sun Lagrange 3 point? Always opposite to the earth relative to the sun. I did some research online and couldn’t find any record of us observing it.
Don’t get your hopes up though. L3 is gravitationally unstable. It is likely that nothing is there besides a weird bend in gravity.
