Confirmation Images of the COMET C/2018 K1 (Weiland)

On 2018 05 25 Henry Weiland an observer with ATLAS-MLO(Asteroid Terrestrial-impact Last Alert System ---Mauna Loa) reported a possible comet to the Minor Planet Center in Cambridge, Massachusetts, USA.  This possible comet was reported using the observer-assigned temporary designation "A1072Wf".  It was posted to the Possible Comet Confirmation Page(PCCP) and came to the attention of observer around the world. On 2018-05-26 I woke up, check iTelescope.net and saw that their facility in Siding Spring Observatory, AU was open. So had T30 started an imaging run of  60 - 60-second luminance BIN2 images and went out to eat breakfast. I got back made four stacks of 5 so can work around "stars that were in the way." I submitted my observations, as more observations came in and as the morning change to the afternoon, I saw my observations had poor residuals, so I did imaging run of  60 - 60-second luminance BIN2 images on T27.

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:

• NEO Confirmation Page(NEOCP) and Possible Comet Confirmation Page (PCCP)
• The Impact Risk Monitoring lists(See Jon Giorgini's "Understanding Risk Pages"  for more inofmation)
• JPL Sentry
• JPL Scout(NEOCP)
• ESA NEODyS CLOMON2 Risk list
• The Radar Support Lists (Arecibo or Goldstone)
• Near-Earth Object Human Space Flight Accessible Targets Study (NHATS)
• ESA's NEO Coordination Centre (NEOCC) Priority List

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.
