"Pseudo-MPEC" for 2013-041B = NORAD 39224 = WGS 6 Rk = S509434

Created 2017 Mar 23 18:23:51 UT using Find_Orb

You'll notice that this has really bad residuals. That's probably due to it having a low perigee (nominally 6621 km above the geocenter, or about 250 km above the surface). This should cause it to reenter sometime around mid-2017.
