...impossible to view AO-51...

I will stick with the information that NASA offers...and sources like astronomer Dave Kornreich (Dave earned his PhD from Cornell in 2001 and is now an assistant professor in the Department of Physics and Physical Science at Humboldt State University in California) -

I did, indeed, see the light of the sun reflecting off of AO-51 earlier this week with the naked eye.
