Hello;
I just do not know if this is happening to me.
You tell me what happens to guide 9.0 and asteroids.
I have placed the asteroids in order and what is my surprise that many asteroids come with Mg? Erroneous? to Mg - 0.5 (2010 LF74 mag
-0.5)
Is this an error or catalog guide MPCORB 9.0?
Or everything is correct.
