Anubis User ID: 35369805 Canada 03/01/2013 09:56 PM Report Abusive Post Report Copyright Violation | For my part I've been working on calculating the uncertainty region of the asteroid. FindOrb wasn't able to generate a file that ORSA could parse correctly until I started generating it with an epoch prior to the comet's eccentricity exceeding 1. That means I now have to integrate it forward in ORSA over a period of 3 years, which is a lot more processor intensive than if FindOrb was allowed to generate it at an epoch near the actual date of the Mars pass, but it's doing the integration right now. Both programs account for the gravity of all the planets, including Mars, so it doesn't much matter aside from the processor/time requirements. I'll check on it tomorrow morning and hopefully the first integration will have completed. Then I will do a second integration with a subset of the solutions that put it closest to mars with a much finer time resolution. Bottom line, I should be able to make a video of this preliminary analysis sometime in the next day or two if all goes well. Quoting: Dr. Astro that would be awesome Doc staying tuned. |

Dr. Astro (OP) Senior Forum Moderator User ID: 4211721 United States 03/01/2013 10:03 PM Report Abusive Post Report Copyright Violation | Working on it. The parsing issue was solved, but the file that could be parsed by ORSA was itself inaccurate; it had all the virtual comet positions plunge straight into the sun at the start of the simulation. Turns out that FindOrb loses accuracy in its oscillating elements at high eccentricities. Not an unworkable problem though because it also generates a separate file of the actual state vectors (I tested them and they're accurate even at high eccentricities). I'm now working on loading those into ORSA, though it has to be done manually. To give you some news about this comet in the meantime though: [link to spaceobs.org] Last Edited by Astromut on 03/01/2013 10:04 PM |

Thanks for the measurements! I will recalculate CA too. Leonid and Re: C/2013 A1 close approach to Mars in October 2014 Posted By: alvitagl Sat Mar 2, 2013 9:19 am Hi all, Thank you for sharing the latest Kitt Peak observations. I have runned the MonteCarlo generation of clones, including the latest observations. After that, the estimated probability of a Mars impact increases, and, moreover, the location of the possible impactors within the uncertainty "cloud" of the virtual comets moves from the border towards the middle of the cloud, in a region of higher density. What happens is that if the clones are generated assuming a lower standard deviation on the individual observations, e.g. . 0.5 arcsecs instead of 1.0 arcsecs, the cloud shrinks, but the virtual impactors are still well inside it, and, since the density increases, the impact probability estimate also increases. The linked image shows a picture of the current prediction taken about half an hour before the possible impact. The generation of clones was made assuming equal weights on all observations (one discarded) and an esd of. 0.5 arcsecs. The projection is on the Mars orbital plane, the white spot represents the nominal solution and the magenta spots are the virtual impactors. In total, 2000 clones are represented. The resulting estimated impact probability is ca. 0.3% [link to www.webalice.it] Later I might post an histogram of the distribution of the closest approach distances. Best regards Aldo Vitagliano |

The thing with science is that you don't know anything for sure until you can run the same data and calculate the same answer over and over. Then and only then can it be confirmed as fact. This thing has only been discovered for two months. It's still far away. As it comes closer the numbers will be more accurate and then they can track it. But knock yourself out accusing. You probably wouldn't know how to calculate the answer yourself, nor do I, which is why I rely on people that do know, like Astro and others here. Why would they not tell?
