Helping With The Confirmation of the Mars-crossing Asteroid 2018 PO23

On 2018-08-13 I check the NEO Confirmation Page(NEOCP) and  an object clalled ZTF00Th.

I was able to obtain a  set of  4-60 second luminance BIN2 images taken with iTelescope.net's (T30) and a set 12-60 second luminance BIN2 images taken with iTelescope.net's (T30). I use Astrometrica to do the data reduction by way of the stack and track method. I had Astrometrica stack 3 sets(stacks) of 3 images.  Each image was shifted match movement of ZTF00Th.

Then I  submitted this batch of  4 observation to the Minor Planet Center.
About 14 hours later I  obtain a  set of  60-60 second luminance BIN2 images taken with iTelescope.net's(T11) I had Astrometrica stack 3 stacks of 15 images ( note a star keep me from having  4 stacks of 15 images)

Then I  submitted this batch of  3 observation to the Minor Planet Center.
After another ten  hours I  obtain a  set of  60-60 second luminance BIN2 images taken with iTelescope.net's(T17) I had Astrometrica stack 3 stacks of 15 images ( note the first 9 images where on the "wrong" side of the meridian flip)

Then I  submitted this batch of 3  observation to the Minor Planet Center.

After 110 observations,  collectively made from 27 observatories from around the world, at Aug. 16.90, 2018 the Minor Planet Center gave  ZTF00Th. the provisional designation 2018 PO23 and removed it form the NEOCP.
