There are 114 new models of asteroids published. You will find them in Scientific Results section.

What is the total number of asteroid models so far?

Very impressive!

I especially like the poster behind the link at the bottom of the page, good publicity for A@H and BOINC. I would like to print that poster and display it in various places around my city (eg. the public library, the local computing club, physics and computer science departments at the local university). May I have permission to use it (unaltered)?

We have 390 models of asteroids.

to Dagorath:
Yes, you can. The publicity is good.

It seems a bit strange, to me anyway, that they are all "fig" shaped. Surely some of them are some other shape?

Well, this method can derive only convex models so there are no detailed models with rocks and craters, if you meant this.

I understand you wouldn't be able to get down to that level of detail. I would have thought some would be spherical, oval or maybe cylindrical shapes. Something other than fig-shaped.

He wanted different shapes but when He and the angel Gabriel were making the asteroids God stubbed his little toe just when Gabriel asked what shape they should be. While He was dancing around in pain, holding his little toe, He yelled "Oh, frig!!" Gabriel, ears still ringing from the Big Bang, replied, "OK, figs it is." and the rest is history.

YES! I've never actually been the volunteer to accomplish anything yet :D!

There is a strong bias in the shapes we derive. The closer the shape is to a sphere, the lower is the variation of the reflected light caused by its rotation. In such cases, the signal is drowned in the noise and we can't derive the rotation period. Given the poor quality of the data we have now, the shape has to be elongated enough to produce a high-amplitude lightcurve - only then we can find the period and the corresponding shape.

When BOINC tells me there's new messages I almost never ever click to view them. When I clicked on the messages I almost never ever click on the announcements to read more. When I follow through I rarely ever take a close look at the results.

For whatever reason I did all of the above and I was surprised discover my computer was one of the ones to get lucky enough to be dished out the WU to do the computation for one of the new models.

Even though it was just luck on my part to get a "winning" WU (there are many other number crunchers out there I'm sure who didn't get in, but crunched just the same) I do find it really really cool that my computer has done something useful. Thanks for sharing the results with us. Often BOINC projects feel like a black hole and it's hard to know what's going with a project. Glad to see you are keeping the community up to date.

(I don't know if you have access to send messages to individual participants, but it may be worth sending individual messages to people whose computers did find a model. My guess is some people in the list may not know they are on it but would find it equally as cool as I do that their computer is on it).

Congrats Granite on finding a new model :)

I was wondering approximately how often the scientific results page is updated with newly computed models of asteroids. Is there a periodicity of the update process, or it happens randomly? When was the last update, when will the next one occur, stuff like that :) On the A@H Twitter account the last update was announced in March 2013, which is quite a while back in time, but I'm guessing that there have been more recent updates too.

New models aren't published periodicaly. We just have to process many results and there if there is enough new models then we will publish them. With the optimization there are much more data for processing now and there is also a change is storing older data which are needed to publish who find right model so there are still no new models published but don't worry, they will be. It is just not scheduled.

Thank you for the info, Kyong!

I'd like to make some small suggestions for making the scientific results page better when you update it next:

1. Add a "last updated" field somewhere, to let us know when new results were published last.
2. Add some number (index) in front of each asteroid model (not the asteroid's own index which is already there, but a new table column with a result index going 1,2,3,4...N). It's easier to find the one you're looking for like this and it also helps knowing how many there are in total.

Thanks!
