  • Hered in These Proceedings with the Aim to Keep Track of These Very Interesting Days
    Proceedings of GAIA-FUN-SSO 2014 Third “Gaia Follow-up Network for Solar System Objects” Workshop held at IMCCE/Paris Observatory 2014, November 24 – 26 Institut de mécanique céleste et de calcul des éphémérides Observatoire de Paris Legal Deposite – June 2015 ISBN 2-910015-73-4 Foreword The observation of Solar System Objects (SSO) by the Gaia space astrometry mission will be constrained by a scanning law. Much detection of interesting objects may occur with no possibility of further observations by the probe. These objects will then require complementary ground-based observations. Among them, previously unknown Near- Earth Objects, fast moving towards the Earth or going away from it could be found. Several objects discovered by Gaia could also be Inner-Earth Objects, as the probe will observe at rather low Solar elongations. In order to confirm from the ground the discoveries made in space and to follow interesting targets, a dedicated network is organized, the Gaia Follow-Up Network. This task is performed in the frame of the Coordination Unit 4 of the Gaia Data Processing and Analysis Consortium (DPAC), devoted to data processing of specific objects. The goal of the network is to improve the knowledge of the orbit of poorly observed targets by astrometric observations on alert. This activity is coordinated by a central node interacting with the Gaia data reduction pipeline all along the mission. In 2010 and 2012, we had organized the first two workshops in order to initiate the network and to meet the participants. In 2014, almost one year after the launch of Gaia, we organize the third Gaia-FUN-SSO workshop in Paris in order to discuss further the coordination of the network of observing stations, to discuss the prelaunch training observations which have been performed and to prepare the network for the operating phase of the alert mode which must begin in 2015.

The software PRISM was used to calibrate the CCD fields and measure the positions of Apophis and 2013 TV135, and our own software was used to Duende. Comparison results have shown that, the ephemerides of INPOP10a and JPL are consistent for Apophis and 2013 TV135, however quite inconsistent for Duende. Moreover, we have found that the mean values of the system errors between the ephemerides of INPOP10a and JPL are about 7200 and ¡19900 in right ascension and declination respectively for Duende, and the ephemeris JPL is reliable with the means of O ¡ C (observed-minus- calculated) residuals in right ascension and declination about 2:7200 and 1:4900.

  • Impact Hazard Communication Risk Study: 2007 VK184 Laura Delgado
    Impact Hazard Communication Risk Study: 2007 VK184 Laura Delgado López, Secure World Foundation Overview The 130-meter sized 2007 VK 184 was discovered in early November 2007 by the NASA-funded Catalina Sky Survey (CSS) at the University of Arizona. According to NASA, 2007 VK 184 was known to pose “the most significant risk of Earth impact over the next 100 years” with a rating of 1 in the Torino Scale, and a 1-in-1800 chance of impact in June 2048 with up to four potential impacts. Analysis was based on 101 observations that took place between 12 Nov 2007 and 11 Jan 2008,1 when the asteroid moved beyond view. It was sighted nearly six years later in March 2014 by Dr. David Tholen of the University of Hawaii who provided the new tracking data to the Minor Planet Center. NASA JPL’s “Sentry” system retrieved the observations and issued a when a new impact hazard assessment which concluded that no closer encounters are predicted for the foreseeable future. Given these observations, the NEO Program Office removed it from the Impact Risk Page. Coverage Media coverage of 2007 VK 184 focused on the initial discovery of the object in late 2007/ early 2008 and then on its demotion from a viable threat earlier this year. The object was mentioned in the intervening years in articles covering other objects, as one of few that represented non- negligible threats. Discovery On 30 December 2007 an Australian newspaper, The Age, reported the discovery in “Space rock on way, but don't panic yet” by Daniel Dasey.

  • Institute of Astronomy Public Open Evening Wednesday 23Rd October 2013
    INSTITUTE OF ASTRONOMY PUBLIC OPEN EVENING WEDNESDAY 23RD OCTOBER 2013 Welcome to our weekly public open evenings at the Institute of Astronomy. Tonight ROBIN CATCHPOLE will be talking about THE SUN AND CLIMATE CHANGE. The talk lasts for about half an hour, and begins promptly at 7.15pm; it will be followed by an opportunity to observe if (and only if…) the weather is clear. Temporarily we only have one of our historical telescopes open for use – the larger Northumberland telescope has been refurbished over the summer, we hope it will be back in action soon with its (very very) shiny brand-new dome. The Thorrowgood telescope is still open, we’ll have some small telescopes out, and the CAMBRIDGE ASTRONOMICAL ASSOCIATION will provide a floorshow with commentary on the observatory lawns relaying live images from three modern telescopes. If we’re unlucky and it’s cloudy, then we’ll offer you a cup of tea and the CAA will offer some more astro-information afterwards in the lecture theatre for those who want to stay on. The talk schedule for this term is available at: www.ast.cam.ac.uk/public/public_observing/talks2013-14 and we TWEET current astr0-news and events as IOACOA. If you have any questions, suggestions or comments about the IoA Open Evenings – particularly suggestions for talks you’d like to hear this year, please get in touch with CAROLIN CRAWFORD [email protected]. In next week’s talk our guest speaker, STEFAN GILLESSEN will be discussing BLACK HOLES - SCIENCE FICTION OR REALITY? JUST BEFORE A MASSIVE STAR GOES BANG W26 is a particularly luminous red supergiant star that is just one of several hundreds of thousands making up the giant star cluster Westerlund 1, some 16,000 light-years away from Earth.

Section One provides a brief discussion of the nature of such claims, the contexts in which they tend to be made and the kinds of probability that they can contain. Section Two provides an overview of the methodologies that have been developed to arrive at these probabilities and assesses their advantages and disadvantages.

  • Studies of Neos As a Task for Small Telescopes V
    Contrib. Astron. Obs. Skalnat´ePleso 43, 434 { 437, (2014) Studies of NEOs as a task for small telescopes V. Tarady1, O. Sergeev1, M. Andreev1, V. Godunova1 and V. Reshetnyk2 1 ICAMER Observatory, National Academy of Sciences of Ukraine, 27 Acad. Zabolotnoho Str., Kyiv, Ukraine (E-mail: [email protected]) 2 National Taras Shevchenko Univ., Faculty of Physics, 4 Acad. Glushkov Ave., Kyiv, Ukraine Received: November 5, 2013; Accepted: January 20, 2014 Abstract. The decades of successful research at the high-altitude observatory Terskol in the Northern Caucasus have yielded new data and findings in the field of monitoring and studies of NEOs. Facilities of the Terskol Observatory, which include optical telescopes with diameters up to 2 m, their instrumenta- tion (high- and low-resolution spectrometers, high-speed photometers, CCDs, etc.), have been heavily used for follow-up astrometry, photometry and spec- troscopy of Earth-approaching asteroids and comets. In this paper, advances in studies of NEOs achieved in the last years at Terskol are presented. Key words: asteroids: astrometry, photometry, spectroscopy { asteroid spec- tral types { NEOs 1. Introduction Beginning in 1996, the facilities of the Terskol Observatory (the Northern Cau- casus, 3100 m asl) contribute significantly to achieving important results in the following fields of research: precise astrometry and photometry of Solar System bodies, monitoring of NEOs and space debris, high-speed photometry of vari- able stars, high-resolution spectroscopy of interstellar clouds, search for optical afterglow of gamma ray bursts, etc. (Tarady et al., 2010). The available small and medium-sized telescopes (Zeiss-2000 and Zeiss-600, as well as Celestron 1100 and Meade 1400) provide good enough opportunities especially for astrometric, photometric, and spectroscopic observations of Earth- approaching asteroids and comets.

The work was launched in the collaboration with Kharkiv Institute of Astronomy within the Memorandum on scientific cooperation between Ilia State University (Georgia) and V. N. Karazin Kharkiv National University (Ukraine) in 2011. In the framework of this study the regular observations of several dozen asteroids per year are carried out to determine the rotation periods, size and shape parameters of these celestial bodies. A broad international cooperation is involved in order to improve the efficiency of the study. Abastumani is included in the observatory network called the Gaia-FUN-SSO, which was created for the ground support of the ESA’s Gaia space mission. Key words: Asteroid, photometry, CCD observations, albedo 1. Introduction Presently mankind has realized and assessed the probability and the scale of the effects of a possible fall of large asteroidal or cometary bodies to the Earth. Recognition of the impact hazard is based on the facts of numerous falls of celestial bodies to the Earth, the Moon and other bodies of the Solar system, which happened in the past and continues to occur today.
