The Recovery on 2nd Opposition of the Asteroid 2011 YS62 From 2015-09-26 To 2015-09-28
Observing Runs Looking for 2011 YS62 from 2015-08-26 to 2015-08-28
When
it comes to target selection there two criteria I use first is would additional
observations be useful, the second is the target in range of the telescope's
capability. To find targets I check one or all of the lists (see below) and see
if the target is range of the telescope's capability (if it is important I will
push the limit of the range) Then I will plan an observing run. Recently I checked the Arecibo Asteroid
Schedule and I saw they had requested optical astrometry for 2011 YS62. At the time this asteroid had a data-arc span
of 89 days and had been unobserved for 1314 days (3.597 years)
First Night
I first did run of 15 - 120 Second Luminance BIN2 Images on itelescope.net's (TEL T27), with no luck,. Next I used Find_Orb to generate new orbital elements with Epoch 2015 Sep 26.0 and did a another run 15. I also used Find_Orb's Monte Carlo function to generate a lot of clones(virtual asteroids) orbital elements and then manually add them to Astrometrica's MPCOrb.dat file. Then I created 3 stacks of 5 images and found a moving object near the known object box of one of the clones. I assigned a temporary designation to the object and submitted night one's observations to the Minor Planet Center.

Second Night
Using Find_Orb I generated two
orbits one was with just night one’s observations, the other with 2011 YS62 and
night one's observations (“updated orbit”) and manually replaced the
"clones" orbital elements. Next I ran a series of 6-120
Second Luminance BIN2 Images on itelescope.net's
(TEL T27) and created a stacks of 5 images and found an object at
the known object box for the "updated orbit". Then I ran a second run of 6 images and created
a stack of 5 and saw that the object was moving. Later on I ran another run of 15 images
and created a 3 more stacks of 5 images. I assigned a (new) temporary
designation to the object and submitted the second night’s observations to
the Minor Planet Center. Shortly thereafter the object was listed on the
NEO Confirmation Page.

Third Night
I did the same orbit update has I did the night before then, I obtain 32--120 Second Luminance BIN2 images with itelescope.net's (TEL T27) and created 3 stacks of 10 image and submitted the third night observations to the Minor Planet Center using the designation that was on the NEO Confirmation Page.
