Names are the people who usually observe at that site, from Project Pluto's tables. MPC's astrometry records only the observatory code, never the individual, so these are not the observer of this particular object. Automated surveys list a telescope and no people.

Drawn from MPC's own variant-orbit offsets, at the same epoch as
their plot. Each orbit is one
solution consistent with the observations so far; the ring marks the nominal
position, and the field box appears only when it is comparable in size to the
cloud.
Dot size shows how many variants share a position. MPC
publishes these offsets rounded to whole arcseconds, so a tightly constrained
object has thousands of orbits landing on a handful of grid points —
their own picture is drawn from unrounded values and looks smoother. Sizing
by count puts that density back rather than stacking invisible dots. Hover any
dot for its share.
