Re-Observing 2015 FP118 Another Look Almost Three Years later

When I am looking objects to observer, I try to find something within the capabilities of the telescope, interesting, and 'needing" observation. To these ends I check following lists:
On 2018-05-28 I saw  that 2015 FP118 was on both the Arecibo and Goldstone lists, needing astrometry,  and it was within the capabilities of iTelescope.net's (T27 TEL 0.70-m f/6.6 reflector + CCD) so I went for it. As I was create a directory so I could downloading the .FITS(Flexible Image Transport System) files I found out that I observed 2015 FP118  for  19.6 min on  2015-06-06.
