An Asteroid as Entered the Blogosphere… Should I Be Worried?

A commentary by Steven M. Tilley

The Asteroid to Earth "Say out my Way!!!!"
Earth to the Asteroid "Watch where you're going ... fool!!!"
Image edited by Steven M. Tilley
(Disclaimer -- Earth and
asteroids CAN NOT talk)
see the original (public domain) image
Planetoid crashing into primordial Earth at
Donald Davis' official site

About every few month or so an asteroid makes waves online. This lead some people to panic. Before anyone panics and does something dumb. One should remember one of the secrets to life, breathe, in and out. Then remember anyone can post anything online. Some sources are better than others when it comes to asteroid information. Sources range from very useful to worse than useless.

First check for reliable information from some of the reliable sources such as the Minor Planet Center, NASA NEO Program Office at JPL, ESA's NEODyS (Near Earth Objects Dynamic Site), or The Tracking News. The writer of this blog post is aware that are many people in the blogosphere who distrusts one or more of the name reliable sources. The author suggests that they reexamine their stand. A significant number of individuals and organizations from around the world observe asteroids; these observations serve as a cross check. If someone or a group makes an error, the error would soon come to light with more observations. If there is nothing about the asteroid from the name from reliable sources most likely, the story probably is wrong.

Another thing to remember as a story moves through the blogosphere it changes like the "telephone game." The original story is misread, poorly translated, misunderstood, etc. then rewritten by other writers with the wrong information. Then other writers then use the revised story as a source for new stories adding to the madness. One should seek out the original story(and see if it is reliable).

When reading up ( and writing) about asteroids one should know the limits of one's knowledge base. Some of bloggers and youtbers out there go way outside of their knowledge base; they think they "know" when they don't "know." The problem is many people mistakenly repost "wrong" blog posts(and videos) adding to the madness. Just because something has been shared, many times does not make it true.

It should be stated that no post is complete without a "good" headline and an image to hook readers. Many times the picture is wrong, and the headline is highly misleading. It takes lots of time to find a picture of the asteroid or use a telescope to image the asteroid in question. This requirement of time will lead many writers to find any old image of any old asteroid. Many times if the author used a real picture of the asteroid internet users would not click.

Finally one should keep studying about asteroid there so much to know. One should not be afraid seeking good answers to questions. Just look for good sources of information.

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.

On 2015 Sept. 28 the Minor Planet Center issued MPEC 2015-S102: 2011 YS62 with the observations from the three nights of and updated orbital elements.
