[Neocp_artsats] C3R7HJ1 = 2016-038C = NORAD 41590 = Falcon 9 stage

[Bill Gray]

Hi folks,

    This is a somewhat unusual case.  The object gets observed by the 
surveys frequently (nice and bright and slow-moving at apogee). 
However,  starting in late May,  the perigee dropped a bit,  drag set 
in,  and the Space-Track TLEs lost it (wrong argument of perigee,  at 
present,  by about 20 degrees.)  Details at

https://www.projectpluto.com/pluto/mpecs/16038c.htm

    As noted there,  the perigee will gradually go back up due to 
lunisolar perturbations over the next few months,  and the orbital 
period will stabilize at a lower level.
