I got me a KBO!... I shall keep it, and pet it, and name it George! smile.gif
Going for spousal brownie points, telling my wife I discovered it for her. International Star Registry can go suck it! tongue.gif

I hate to think what my false positive rate must be for me to have spotted that one... but to be the only one who did? I'll have to start wearing knit hats because I won't be able to get a regular one big enough!

Just a quick question - did anyone else experience trouble in creating a Zooniverse account when they began hunting KBOs? I'd like to help, but I can't seem to register for some reason.

Looks like I got one too! First to spot it (by 38 seconds!). IH-267996.

...but will it get a visit?

Oh, my.

Whodda thought? It was quite difficult going through those pictures and not wanting to flag every little blip, but not wanting to miss maybe a significant little nugget either.

I assume most of these 'rocks' won't get much in the way of follow up observation time unless they look really primo for a NH encounter. Still, if any of them have odd or unexpected orbital inclinations or eccentricities, it would be interesting to know and compare to some of the other unusual ones we already know about.

BTW, for the objects with multiple images, are there any unexpectedly large brightness variations among the images? Seems like a large brightness variation might be indicative of global dichotomy or an elongated object, making for an object a little more interesting than the others.

Hoping the NH team gets a real gem or two for the extended mission!

You have to remember that the discovery "images" on icehunters are not single images, but algorithmic mergers of several. I don't think you can address the questions you're raising from them.

I don't know about the registration problem, but there are no new images to analyze right now. From these posts in the IceHunters forum, I gather it may be weeks - or months (depending on what "a while" turns out to be) before new images are available and when they are, the search may continue at a different web site: http://cosmoquest.org./

Thanks for the reply. It turns out I couldn't register due to the maddening technical hitch of my being unable to read simple English... rolleyes.gif

I managed it in the end, thank goodness. It's a fine site. I am thinking about helping out with the 'planet hunters' project in due course - or while we wait for another cache of KBO images!

I didn't figure out how to search just for ones that I'm listed on, but I looked through the roughly 150 confirmed KBOs and noticed my ID on three of them. I'd gone through about 20,000 images, so by the above suggestion should have seen about ten, but it is hard to know, and I'd have to say a large fraction of the images I searched were unusable... so maybe three is right.

^ The poster on the forum at icehunters said (s)he'd started late, so some of his 1-in-2000 "discoveries" were no doubt images be refloated to the top of the queue to get more looks. Indeed there were probably a lot of images that got skimmed by a few people and then thrown out of circulation.

Just noticed the following in the IceHunters forum.
I used the starstryder@gmail.com address and got a form e-mail back saying Pamela was traveling. I see nprev on the Name Needed list in case anyone wants to get word to him.

Gnsorgathon was the sole discoverer of one... I'm not sure how that sort of thing got followed up?...
Just found out myself. Clicking on the "?" in upper right on the catalog pages gives general information including, "Scientist Confirmation: Scientists review all marks - even those with a single click (but those are de-prioritized)." Objects with three clicks were reviewed first.

SEARCHING FOR KBO FLYBY TARGETS FOR THE NEW HORIZONS MISSION
QUOTE
Results so Far: We have identified 24 KBOs in the 2004/2005 data, some with arc lengths up to 1 year, and so far about 18 unique KBOs in the 2011 data (Table 1), though analysis of the 2011 data is not yet complete. No KBO yet found is reachable by New Horizons, but the closest one to the NH trajectory would require less than twice the available onboard delta-V to be targeted
