Re: Any "Humanity Star" sightings?

It seems clear to me that the initial orbits for the
cubesat dispenser and "Humanity Star" payload and the
rocket body are the 289 by 533 Km eccentric orbits for objects
18-10A, 18-10D and 18-010F (43163, 42166 and 43168).

Then the dispenser released the cubsats near its apogee
into the 500 by 530 Km orbits for the other three objects.

The "Humanity Star" object should have the highest area to mass ratio
and also the highest drag.

JSpOC shows a "zero" drag for all six objects.  But the changing
mean motion shows the true drag.

The 18-010F (43168) object shows a far higher drag than the other objects.

My guess is that it is the "Humanity Star" object.

Its drag seems consistent with the guess that this object will
decay after about 9 months.

The "where is it now" map is

It appears to me that this plot is for the "A" object (43166).
