Дима, 2 фото, что ты добавил, а убрал, были абстрактные- телескоп вообще непонятно чей, а укрытие - из Благовещенска. Это они в предыдущей новости тиснули, поскольку реальных фото не было.

А сейчас впервые именно реальные фото

"Pseudo-MPEC" for 2019 OK = S511618 = asassn3

This object was initially found by SONEAR in Brazil, with a short arc of three observations, not enough to tell us much except that it had to be close to us. They posted the data as a new object on the NEOCP under their designation, S511618.

Shortly afterward, the ASAS-SN (All-Sky Automated Survey for Supernovae) found a moving object in their images, and posted the data to NEOCP with the designation asassn3. Things were a little confused here. As the name indicates, ASAS-SN focusses on supernovae (and finds a lot of variable stars and some galactic novae). Their data were posted as having come from the observatory codes (711) McDonald Observatory in Texas and (F65) Faulkes Telescope North in Haleakalā, Hawaii, but were not from the telescopes actually at those locations; the ASAS-SN telescopes share domes there. The data were posted to the Possible Comet Confirmation Page even though the object wasn't at all a possible comet. Supernova surveying can be done with large pixels and poor astrometry, but when we see 5" residuals from (711) and (F65), we're usually thinking "bad data".

Neither arc, by itself, looked all that unusual. Put together, they fit into an orbit that would pass us at about 71000 +/- 1000 km in a mere four hours. (The orbital elements after collecting all the data gave a perigee distance of 71359.03 +/- 2.33 km from the center of the earth.)

However, I didn't realize the (711) and (F65) data were actually from ASAS-SN. If I had, the large residuals would have been to be expected; they aren't asteroid astrometry folks. I thought the data were coming from the "usual" McDonald and FTN scopes; coming from them, the data looked suspiciously bad.

So I took the possibility that S511618 and asassn3 were the same object with a big grain of salt. It seemed likely to me that the (711) and (F65) data were just wrong. But I posted a request on MPML for observations on the theory that the best way to find out if the linkage was real was to look for the object in the place you'd expect to see it. (Which would be a relatively small area of sky with a very bright object.)

Very shortly after I posted that request, (F51) PanSTARRS went through their archives and realized they had some data for the object, which firmed up the orbit tremendously and confirmed that the linkage was real. I got an e-mail explaining the situation for the ASAS-SN data from (711) and (F65), so that mystery went away. The object was rather low on the horizon as seen from Europe, but two ISON stations were able to track them (it probably helped that these objects were really bright, as NEOs go.)

We now have radar data for this object from Arecibo, which (as often happens with radar) really firms up the orbit. The Doppler (radial velocity) measurement fits to within 1.2 sigmas; the ranging data fit almost exactly. (Though the radar guys tend to lowball their uncertainties. I really ought to adjust them by about a factor of three to get them to match the sigmas given to optical data.)

If you look at the along-track/cross-track residuals, you'll see some systematic timing errors near perigee, of the sort that often crop up with fast-movers. I'm hoping the stations involved will check their timing by observing GPS/navigation satellites. If they do, and if their timing is reasonably consistent ("hmmm, our clocks are off by -5.4 seconds, and were probably off by the same amount when we observed 2019 OK"), then we should be able to recompute the orbit using corrected times. I hope.

Статья Шустова Б.М. "О роли науки в изучении и парировании космических угроз":

http://www.inasan.ru/wp-content/uploads/2019/10/Статья-о-космических-угрозах-Вестник-РАН.pdf

На стр. 781:

Следует  отметить  существенный,  причём на протяжении многих лет, вклад в наблюдения большой академической сети ISON (International Scientific Optical Network), поддерживаемой ИПМ им. М. В. Келдыша РАН, которая предназначена в основном для регистрации космического мусора с помощью телескопов класса 50 – 70 см. Значительная часть базы данных космического мусора ИПМ РАН основана на наблюдениях сети ISON, особенно наблюдений объектов в зоне геостационарной орбиты. Иллюстрацией может служить мгновенный снимок распределения КМ в ОКП (рис.  2).  Хорошо  выделяются  сгущения  КМ на низких орбитах и в области геосинхронных орбит. Важной особенностью сети ISON является её широкое распространение по планете.

На стр. 785:

Российские учёные и специалисты участвуют в международной кооперации по обнаружению ОНТ, но, к сожалению, вклад наших наземных средств – обсерваторий и сетей ISON и МАСТЕР (МГУ им. М. В. Ломоносова) – пока весьма скромен и не превышает 0,1 % от общего числа открытий АСЗ.

Small telescopes and their application in space debris research and space surveillance tracking

2.2. The International scientific optical network

The largest civilian network performing the SST function is the International scientific optical network (ISON) operated by the Keldych Institute of Applied Mathematics, Russian Academy of Sciences, Russia. There are more than three dozen of observation facilities worldwide contributing to the ISON network. ISON is continuously increasing its coverage and currently contains 90 telescopes with apertures in range from 0.125 m to 2.6 m (Mokhnatkin et al., 2017). A majority of the telescopes’ operators are from academic institutions. ISON focuses on the cataloguing and research of objects on higher orbits and Near Earth Asteroids (NEA). Three ISON telescopes, a 64-cm AT-64 (a), a 2.6-m ZTSh in Nauchniy-1 (b) and a new 50-cm VT-40/500 in Ussuriysk (c) are shown in Fig. 2. The 2.6-m ZTSh telescope, situated in Nauchny, is the telescope with the largest aperture from all sensors contributing to ISON.

The geographic distribution of the ISON telescopes and its cooperating telescopes as to 2017 are plotted in Fig. 3. Most of the ISON telescopes are situated in the Russian Federation but are continuously deployed to other locations such as South and North America, Australia and Africa.
...

4. Summary

Space surveillance of space debris is essential for space operations safety and long-term sustainability. Surveillance networks such as USSTRATCOM and the Russian ISON are widely using optical sensors/telescopes, which discover new objects and maintain their own catalogues. Both systems’ data is publicly available and largely used by different subjects, from governmental entities and space agencies to academic researchers.

Small optical telescopes play a crucial role in space debris research and space surveillance tracking. Their role in space safety will increase in the next few years due to the large privatization of the space industry, which will bring new challenges like the mega-constellation projects.

5.1 MORE SENSORS

Several other actors are developing their own comparable SSA networks as well. The Russian International Scientific Optical Network (ISON) expanded its number of instruments to more than 50 telescopes located in 17 countries, primarily for GEO observations [27]. Over the last 10 years, ISON multiplied the number of its daily detections by a factor of 200 [28].

Along the ancient Silk Road

....

Rolling all the way down the next day, we stopped first at Kitob, where we had a Couchsurfing host, our only host in the country. Our host himself lives in Tashkent, but his parents hosted us, and what an experience! Not only were we fed and treated like family, we also got a glimpse into the work that they do. His parents are observers with the International Scientific Optical Network (ISON), and they have an observatory with four telescopes that are mostly used for the observation of space debris. Every night, one of them works the whole night through, taking astronomical photos that are sent to the headquarters in Moscow for analysis. With the data collected by observers like them from all across the globe, active satellites can be steered away from potential collisions with space debris, an increasing problem in space.

Tracking and Identifying Anonymous ISON Satellites

The Russian based ISON (International Scientific Optical Network) provides a weekly update of a catalog
listing manmade objects in Earth orbit for which no obvious match exists. The “ISON catalog” is
maintained at http://spacedata.vimpel.ru/ As stated on that website, “Orbits with a period of over 200
minutes are mainly investigated, which basically include geostationary space objects and objects with
large eccentricity orbits.

One of the other main entities that track satellites is ISON. As stated on the data portal, “OJSC Vimpel,
which has a unique 40-years’ experience in developing , testing and practical implementation of
software for carrying out the various tasks associated with maintaining the catalog of artificial space
objects…Hundreds of previously unknown space debris objects were found, including substantially large
objects, that formed over decades of space activity, but which were not duly tracked by ground-based
monitoring stations and as a result have been lost.” This situation can come about from the many
difficulties faced when tracking the tens of thousands of objects in orbit above us.

Among the hundreds of ISON objects are most of the classified satellites cataloged (as classfd.tle) and
tracked by Seesat. Through the arduous efforts of many observers and analysts, most of the classfd.tle
objects were correlated with ISON objects prior to this study. However, there remained a fair number of
objects being routinely tracked by ISON that were reported to have standard magnitudes of 8.0 or
brighter. This indicated these objects might be independently monitored by hobbyists, and perhaps
identified. I had been observing ISON objects but had not systematically approached tracking them. I
developed an unidentified ISON target list, widened my approach with global remote imaging, and set
these goals:
1. Identify more of these anonymous ISON objects using the Space-Track and Seesat TLE files
2. Determine which objects are consistently trackable using equipment available to amateurs
3. Identify origin of objects that are trackable but do not directly correlate with known objects


Over the course of a yearlong effort, 153 anonymous objects from the ISON catalog were observed to
determine ones that were trackable and potentially identifiable. 89 objects were reported with at least
one set of positional data. Of the 52 total objects identified by Seesat, 35 were found by this imaging
and tracking method. 44 of the total 52 hits were found in the unclassified catalog. The 8 classified
objects involved have since become unclassified and appear in the Space Track catalog.

UNOOSA and the Keldysh Institute of Applied Mathematics are working on an Announcement of Opportunity to provide telescopes to institutions in developing countries

VIENNA, 24 December (UN Information Service) - The United Nations Office for Outer Space Affairs (UNOOSA) and the Keldysh Institute of Applied Mathematics (KIAM), on behalf of the International Scientific Optical Network (ISON), signed a Memorandum of Understanding (MoU) on 14 June 2019. The objective of this MoU is to provide the opportunity for selected academic and research institutions in developing countries to receive small telescopes and training to operate them free of charge. UNOOSA and KIAM are working on this Announcement of Opportunity (AO), expected to be published in early 2020. The selected institutions will benefit from the experience of ISON and will have the chance to take part in global observation campaigns and distribute observation data openly and freely.

ISON is an open international project consisting of more than 50 installed telescopes in 20 observatories in different countries. ISON is managed by KIAM, part of the Russian Academy of Sciences, and it has been credited with the discovery of eight comets, 17 near Earth asteroids and around 1,500 asteroids in the main asteroid belt. It is now one of the largest observation systems in the world. Acquiring a small telescope can help receiving institutions contribute to scientific progress and join international exchanges in the observation field.

The AO will be part of UNOOSA' s Access to Space 4 All initiative, which already provides a portfolio of research and orbital opportunities for all countries, in particular developing countries, to access space and its innovative tools.

Simonetta Di Pippo, Director of UNOOSA, said: "UNOOSA is proud to be working on such an exciting initiative that will make a concrete difference for receiving institutions, empowering their talents to contribute to global scientific advancements and knowledge exchanges. At UNOOSA, we aim to bridge the gap between space-faring and non-space faring nations, to ensure that everyone, everywhere, can benefit from space. The Access to Space 4 All Initiative was created with this goal in mind, and this partnership is a welcome addition to its portfolio. By empowering recipient institutions, this opportunity will contribute to advance their countries' space related activities, in line with the objectives of the Initiative."

"ISON is an open international non-government project mainly aimed at being a free source of information on space objects for scientific analysis and other applications. International cooperation has always been at the heart of big astronomical projects. Observations that requires covering the complete sky stimulate large international cooperation and are fundamental for many scientific fields," said Igor Molotov, coordinator of ISON project and senior researcher of KIAM who added: "UNOOSA works to promote international cooperation on the peaceful uses of outer space, so this collaboration is natural."

The Announcement of Opportunity will be posted on the Access to Space 4 All pages on the UNOOSA website (https://www.unoosa.org/oosa/en/ourwork/access2space4all/index.html).

Перевод

ЮНООСА и Институт прикладной математики имени Келдыша работают над объявлением о возможности предоставления телескопов учреждениям в развивающихся странах

Вена, 24 декабря (информационная служба ООН) - 14 июня 2019 года Управление Организации Объединенных Наций по вопросам космического пространства (ЮНООСА) и Институт прикладной математики имени Келдыша (KIAM) от имени Международной научной оптической сети (Исон) подписали меморандум о взаимопонимании. Цель настоящего Меморандума заключается в том, чтобы предоставить отдельным академическим и научно-исследовательским учреждениям в развивающихся странах возможность бесплатно получать небольшие телескопы и обучать их работе. UNOOSA и KIAM работают над этим объявлением о возможностях (AO), которое, как ожидается, будет опубликовано в начале 2020 года. Отобранные учреждения воспользуются опытом ISON и получат возможность участвовать в глобальных кампаниях по наблюдению и распространять данные наблюдений открыто и свободно.

ISON-это открытый международный проект, состоящий из более чем 50 установленных телескопов в 20 обсерваториях разных стран. ISON управляется KIAM, входящим в состав Российской академии наук, и ему приписывают открытие восьми комет, 17 околоземных астероидов и около 1500 астероидов в главном поясе астероидов. В настоящее время это одна из крупнейших систем наблюдения в мире. Приобретение небольшого телескопа может помочь принимающим учреждениям внести свой вклад в научный прогресс и присоединиться к международным обменам в области наблюдений.

АО будет являться частью инициативы ЮНООСА "доступ к космосу 4 All", которая уже обеспечивает портфель исследовательских и орбитальных возможностей для всех стран, в частности развивающихся стран, для доступа к космосу и его инновационным инструментам.

Симонетта ди Пиппо, директор UNOOSA, сказала: "UNOOSA гордится тем, что работает над такой захватывающей инициативой, которая будет иметь конкретное значение для принимающих учреждений, позволяя их талантам вносить вклад в глобальные научные достижения и обмен знаниями. В UNOOSA мы стремимся преодолеть разрыв между космическими и некосмическими странами, чтобы обеспечить, чтобы все и везде могли извлечь выгоду из космоса. Вся инициатива "доступ к пространству 4" была создана с этой целью, и это партнерство является желанным дополнением к ее портфолио. Расширяя возможности учреждений-получателей помощи, эта возможность будет способствовать продвижению космической деятельности их стран в соответствии с целями инициативы."

"ISON-это открытый международный неправительственный проект, направленный главным образом на то, чтобы быть свободным источником информации о космических объектах для научного анализа и других применений. Международное сотрудничество всегда было в центре больших астрономических проектов. Наблюдения, которые требуют полного покрытия неба, стимулируют крупное международное сотрудничество и являются фундаментальными для многих научных областей", - сказал Игорь Молотов, координатор проекта ISON и старший научный сотрудник Киам, который добавил: "UNOOSA работает над продвижением международного сотрудничества в области мирного использования космического пространства, поэтому это сотрудничество естественно."

Объявление о возможности будет размещено на всех страницах сайта UNOOSA Access to Space 4 (https://www.unoosa.org/oosa/en/ourwork/access2space4all/index.html).

The ZTF Survey scores the asteroid with the smallest aphelion distance

09 January 2020

The year has just started, and we already have a very interesting discovery of a new and so far unique asteroid.

The Zwicky Transient Facility (ZTF), a survey program currently operating the Samuel Oschin Telescope at the Palomar Observatory, has been dedicating some time to survey observations at very low solar elongations. These observations are capable of finding objects with orbits located entirely within the orbit of the Earth, the so-called Atira objects, or IEOs (Interior-Earth Objects). ZTF had already found quite a few of them last year, including 2019 AQ3, the asteroid with the shortest known orbital period. So far, only about 20 are known, showing how difficult it is to discover them.

On 4 January 2020 they were observing an area at less than 40° of elongation from the Sun, when they discovered a new object that looked like a promising Atira candidate. Subsequent observations showed that the object was even more interesting: with an aphelion at just 0.654 au, the object's orbit is entirely contained within the orbit of planet Venus, making it the first known representative of the so-called "Vatira" class, the Venusian equivalent of Earth's Atiras.

The object is now designated 2020 AV2. It has an orbital period of 151 days, almost identical to 2019 AQ3, but its lower eccentricity of just 0.178 makes it the natural object with the smallest known aphelion in our Solar System (except for planet Mercury).

2020 AV2 observed from the Abastumani observatory in Georgia on 6 January 2020, in the context of our collaboration with the ISON network. At the time of the observation, the asteroid was located just 20° over the local horizon, at an elongation of 39° from the Sun.
