Andrushivka Astronomical Observatory ABSTRACT OBSERVATORIES OF THE ASPIN PROGRAM ASPIN (Asteroid Search and Photometry Iniave) - ISON asteroid program started in September 2003 at Andrushivka astronomical observatory (A50, Andrushivka, Ukraine). For these purposes was used Zeiss-600 telescope with small CCD camera. In 2009, telescope was upgraded by new full-format CCD camera and lens corrector, which increased FOV to 72’x72’. During first 7 years, observatory discovered more than 350 asteroids, include 2 NEAs. Unfortunately, at present me, when rivalry of surveys was growing up, Andrushivka forced to stop observaon in 2013, due to bad astroclimate and, as result, low magnitude limit. In 2014, we planning to install new, wide-field ORI-50M (0.5-m f/2.3) telescope at new site with good astroclimate condions. Aer that, survey program will resume. Next ISON observatory, which started own survey, was ISON-NM (H15, Mayhill, NM, USA). Survey work started in July 2010 and connues to this day. First telescope of this Andrushivka observatory was Centurion-18, 0.45-m f/2.8 with full-frame CCD camera. In September 2013 with telescope replaced by our new telescope Santel-400AN (0.4-m f/3) with Chuguev Khuraltogot Kislovodsk 105’x105’ FOV. Telescope installed at new AP 1600GTO mount. Both telescopes was controlling remotely from Moscow. At ISON-NM was discovered more than 1,400 Ussuriysk asteroids, include 5 NEOs and 2 comets – well-known C/2010 X1 (Elenin) , P/2011 NO1 (Elenin) . Obtained more than 450,000 observaons of small bodies. Except survey work, Simeiz Tien-Shan ISON-NM carry out photometric observaons of NEAs, obtained dozens lightcurves, determined rotaonal period for more than 20 NEAs, include extremely close and fast Mayhill Abastumani Majdanak rotators, such a 2012 KP24, 2012 KT42, 2012 LZ1 and Duende (2012 DA14) . Since April 2012, another observatory joined to ASPIN – ISON-Kislovodsk (D00, near Kislovodsk, North Caucasus, Russia). At observatory installed one (and first) of two Santel-400AN telescopes with full-frame CCD camera, provided 105’x105’ FOV. At present me, ISON-Kislovodsk - second of all APSIN observatories by number of measurements and discoveries. For 2 years observatory discovered about 100 new asteroids, include 1 NEA and famous comet C/2012 S1 (ISON) . More than 80,000 measurements obtained. In 2013, ISON started using very wide-field telescope VT-73e (0.19-m f/1.5) with FOV 7°x4.5°, for chasing comets and bright NEAs. As first result – discovering new comet C/2013 V3 (Nevski) . Next step of ASPIN program was installaon of our biggest wide-field telescope Santel-650A (0.65-m f/2) in September 2013 at ISON-Ussuriysk observatory (C15). With 50x50mm CCD chip, FOV of telescope is 132’x132’. Test survey observaons started in December 2013. During first two months, obtained more than 10,000 measurements and 3 new asteroids discovered. Furthermore, we ready for producon absolutely new prototype (Project 400/500) of paired 0.4-m surveys telescopes with extremely wide FOV - 11.2°x5.6° with Kodak KAF-4301 and 13.8°x6.9° with more expensive Fairchild CCD-486. In binocular mode, this instrument may cover about 2500 sq. degrees per night with limit magnitude about 20m. All data obtained during survey observaons processed by our CoLiTec package, in near real-me mode. Main features of processing pipeline: cosmec correcon, astrometric and photometric reducon, detecon of moving objects, idenficaon detected object with MPC database, interacve filtraon of detected objects by operator via GUI, sending all approved object to MPC or directly to NEOCP. Preparing sky coverage report. More info about CoLiTec - hp://www.neoastroso.com/?lang=en_us In addion to survey's telescopes, APSIN include a photometric and, in the near future – follow-up sub-networks. For photometric tasks, ISON used 0.4-2.6-m telescopes with small and moderate FOV. Already obtained hundreds lightcurves , defined rotaonal period for dozens NEAs, discovered 6 binary systems . Carried out observaons in support of the study YORP effect. Follow-up sub-network will be use medium aperture telescopes for astrometric support recently discovered NEAs and other unusual objects, by ISON network or objects posted at NEOCP by other observatories. Four 0.4-0.5-m telescopes already installed in Kislovodsk (Russia), Blagoveschensk (Russia), Khureltogot (Mongolia) and Sinaloa (Mexico).

  • Comet ISON 26 November 2013
    Q&A: Comet ISON 26 November 2013 billion years ago. It's been traveling from the outer edge of the solar system for about five-and-a-half million years to reach us in the inner solar system, and it's going to make an extremely close approach to the sun and hence could become very bright and possibly a very easy naked-eye object in early December. What will happen to comet ISON on Thanksgiving? So there are three possibilities when this comet rounds the sun on Thanksgiving Day 2013 [Nov. 28]. It could be tough enough to survive the passage of the sun and be a fairly bright naked-eye object in the early morning sky in the first week of December. Or, the sun could actually pull it apart. The tidal forces could actually pull this comet apart and so it becomes several chunks rounding the sun Comet ISON appeared in the higher-resolution HI-1 camera on NASA's STEREO-A spacecraft.

However, in the time since the publication of Asteroids III, evolution of astronomical instrumentation, laboratory capabilities, and theoretical models have led to great advances in our understanding of H2O/OH on small bodies, and spacecraft observations of the Moon and Vesta have important implications for our interpretations of the asteroidal population. We begin this chapter with the importance of water/OH in asteroids, after which we will discuss their spectral features throughout the visible and near-infrared. We continue with an overview of the findings in meteorites and asteroids, closing with a discussion of future opportunities, the results from which we can anticipate finding in Asteroids V. Because this topic is of broad importance to asteroids, we also point to relevant in-depth discussions elsewhere in this volume. 1 Water ice sublimation and processes that create, incorporate, or deliver volatiles to the asteroid belt 1.1 Accretion/Solar system formation The concept of the “snow line” (also known as “water-frost line”) is often used in discussing the water inventory of small bodies in our solar system. The snow line is the heliocentric distance at which water ice is stable enough to be accreted into planetesimals.

  • On the Russian Contribution to the IAWN
    IAWN Steering Group Meeting Minor Planet Center & Harvard-Smithsonian Center for Astrophysics 13 – 14 January 2014 On the Russian contribution to the IAWN Boris Shustov Institute of Astronomy, RAS Plan of the talk ! " The need for a national NEO program ! " Astronomical requirements for NEO detection/ monitoring ! " Existing premises and recent activities ! " What we plan to do ! " How to contribute to the IAWN 2 Arguments pro national program in Russia (NEO aspects) 1." The NEO problem is a multi-problem. Various organizations (ministries) are to be involved (coordinated); 2." The expensive technologies of massive detection of NEO, preventing collisions and mitigation can be proposed but cannot be realized under the responsibility of individual research institution; 3." Cooperation of countries on the NEO problem implies the involvement of Russia Government (or authorized body); 4." Regular funding is vitally important for real progress. 3 Suggestion to the definitions of hazardous celestial bodies (HCB) PHO - MOID < 0.05 A.U. Threatening object (TO) D < LD, D - 3σD < RE Collisional object (CO) D < RE, 3σD < RE NB: In the definition of PHO limiting size (or H) is not included! -3 6 -4 For TO collision probability >~10 , (if LD = 10 km then >~10 ) For CO collision probability >~0.5 4 Two tasks and modes of detection Large Distant Detection (LDD). Major goal is to detect “all” PHO larger than ~ 50 m well beforehand (to ensure possibility of active counteraction). Near Earth Detection (NED). Major goal – to detect “all” PHO larger than ~ 5 m in the near space (D < LD). This makes possible warning. “all” means > 90% 5 LDD mode: NEO detection (general requirements and other inputs for design of detection instrument ) ! " Time interval between detection+characterisation and rendez-vous must be not less than warning time (tw).

From the outset, Comet C/2012 S1 (also known as As this is being written, only a few weeks after the Comet ISON after the International Scientific Optical discovery with Comet ISON still 6 a.u. from the Sun, it’s Network involved with its discovery) was wrapped in a unclear whether the comet’s orbit is parabolic or very swirl of hype and controversy.

  • The Comets Are Here!
    Comets in the sky in 2014 As of July 2013 there were 4,894 known comets, and this number is steadily increasing. However, this represents only a tiny fraction of the total potential comet population, as the reservoir of comet-like bodies in the outer Solar System may number one trillion. Roughly one comet per year is visible to the naked eye, though many of these are faint and unspectacular. Particularly bright examples are called "Great Comets". A comet goes by many names, the most important of which to its discoverer is his or her surname. Many bright comets that frequently return retain their popular names, such as Comet Halley. (Halley did not discover the comet, but he predicted its orbit and return.) Frequently, two or more observers discover a comet simultaneously or independently. The names of the first three observers to report their discovery properly are affixed to the new comet. The rapid growth in the number of known comets has prompted the International Astronomical Union (IAU) to catalogue them according to precise rules. A new cometary designation system was adopted 1 January 1995. The new system resembles that of minor planets, with objects recorded by the half-month. Thus the third comet reported as discovered during the second half of February 1997 would be designated 1997 D3. When appropriate, the nature (or suggested nature) of an object can be indicated by preceding the designation with A/ (for minor planet), C/ (for comet), P/ (for periodic comet), etc. Hence, under the new cometary designation system, Comet Hale-Bopp was designated C/1995 O1.
