OK, this is the first time playing with asteroids since I got Guide 9.

I downloaded todays MPCORB.DAT file and placed it in both the Guide9 folder and the Guide9/asteroid folder. Which one should it be in? I put a copy in both just to cover my bases.

To be safe, I zomed in to 15 arc-minute FOV and in "Data Shown" turned Asteroids ON.

In the Extras dropdown menu, in the Asteroid/Comet options, I checked the "Use MPCORB" checkbox.

I tried finding asteroid 2000 AT4, and then I tried asteroid 75571 (same rock).

Both come up with the dialogue box "Not an asteroid!"

What am I doing wrong?

Thanks! -Scott
