... I have to say that with so many distracting (now confirmed) variable stars, I wasn't looking for stuff this tiny.


I was looking for stuff that tiny, and found quite a few, but the majority of the images they gave us were so noisy or messy that such small things couldn't be spotted.

That is true. This slew of images was repeats. Those things were flagged for followup even before I tagged them.

After a prolific start (almost 19,000 images viewed) I have to admit I've been away from Icehunters for awhile. I finally check back in and see this smile.gif :

Checking the Icehunter forums, it seems that people are waiting for a list of identified KBOs. This is that latest pertinent information I could find:

Yes, all the Subaru images from 2004/2005, and from 2011, have now been searched, and a bunch of KBOs have been found as a result, though so far none are obvious targets for New Horizons. A list of discoveries, and official thanks to all the volunteers, will indeed be posted soon.

There will probably be additional posts in the next few months of some of our Magellan data on a new site, CosmoQuest, which will have much the same functionality as IceHunters, so stay tuned.

Thanks again to everyone,
John

Has there been more extensive review beyond this?

The number "reviewed" hasn't changed in quite awhile, and sure enough, it seems that I can go in an find big beautiful blobs marked by 45 people that seemingly are marked only as "likely KBO / Variable Star" which would seem to indicate it's not been sorted into the review/not review piles yet.

I've not been doing those reviews or updates, so I can't answer directly, but I do know that essentially all the data generated by Ice Hunters has been sorted through, and the real KBOs have been extracted and compiled. We are however behind in posting the results, and we're working on fixing that.

Yay! The icehunter results are up and I was among those marking three of the confirmed KBOs. The first to mark one of them!

I don't know who this Sergei Schmalz guy is, but he was the first to mark at least 5 KBOs. It would have been 6 but I beat him by two minutes on one. laugh.gif

A good tip for those looking for a particular screen name was given in the forums: "most browsers have a find function, use ctrl+f then type your username." This worked for me using Firefox. Note that you need to re-click on "highlight all" for each page.

Looks like Nick (NPrev) got one: IH-105036 (KBO) which is on page four of the current layout.

EDIT: also Ian_Regan, TASP, tdemko, and antoniseb .... (that I recognize anyway)

congratulations to the discoverers and to the IceHunters Team for the success of this project!!

Alas, my objects are all stars, 'roids, or unclassified... no KBOs for me.

Why does the asteroid gallery say "no orbital elements"? I would think they would be easier to determine than the KBO ephemeris, and it would be interesting to know what type of asteroids they are. I realize that's not useful for New Horizons, but isn't there the potential for follow up observations to confirm these too?

I wonder what "unclassified" implies? I'm sure some of these might be hot pixels or cosmic rays, but some really look like diffuse KBOs. I wonder if these are image artifacts, or if there was not enough information to classify them and could potentially be an interesting object?

"Hero" laugh.gif

Well... I didn't save any lives, or feed the poor, or.... but it is nice to think that somewhere out there is a chunk of ice that I was the first to see (by two minutes.) smile.gif

I found the timeline of discoveries interesting. All three of the KBOs I featured in my previous post were "discovered" over a span of just 45 minutes.

I thought it would be more like what we see below. The time-span from first to last discovery is seven months. What an age we live in when some of the most sophisticated machines built by man can take pictures of space objects that are then put on the internet where one is discovered by SickChick79!

Gnsorgathon was the sole discoverer of one... I'm not sure how that sort of thing got followed up? There were a few others. Perhaps the mark was in line with some others?

Me too. Though I'm tied for first on three "Asteroid IDs," whatever that means. Not sure if it means they simply look like an asteroid, or if they've been correlated with a catalog, or if they precovered or observed them elsewhere...

I got me a KBO! I'm pretty surprised actually, I only had ~3k images searched.

http://www.icehunters.org/object.php?mid=77557

I shall keep it, and pet it, and name it George! smile.gif

Edit:
re: Asteroids not having elements

Here is a response from Pamela (sic):

starstryder (admin) in response to gonano
The times are all there because people wanted to know who found things first. If we had sufficient data to get orbits fro the asteroids (and we don't seem to) then it would matter for naming. As it stands, it's mostly the "OH COOL - I saw it first" factor.

So, it's really just bragging rights, but I think that's cool in it self :-)

Cheers,

Pamela

I had 1441 images. Looks like statistically (from some stats by a forum user), you could reasonably expect 1 in 2000.
