Go for it. I just notified JSpOC to name catalog 43017 as AO-91.

If all of you are OK with Object 43017 as AO-91, I will make the change Thursday. 11-30-2017.

Nico,
I get the same identification using a different technique. While I haven't had time to characterize the AO-91 transmitter frequency dependence on temperature, in AO-85 is was about -62 Hz/degree C. Looking at the changing temperatures, that converts to about the same value in AO-91.
