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.

The Asteroid (357439) = 2004 BL86 On 2015-01-25

The NEO (357439) 2004 BL86 (Orbit type: Apollo ) (estimated to be 440–1000 meters in diameter) will safely make a Close-Approach of 3.1 Lunar Distance on 26 January 2015. This will be the closest known Approach by something this large (H = 19.0) until 2027, and will briefly peak at around apparent magnitude 9.0 It has been schedule for Goldstone Observations(2015 Jan 27-Feb 1).
