An analysis of monitoring observations for the pulsar PSR B0655+64, which is located in a binary system, at 111 MHz during 2002–2015 are presented. The Keplerian parameters of the pulsar have been refived: the longitude of periastron ω = 276. °5785 ± 0. °0005 and the orbital semi-major axis is a p sin i = 4.124976± 0.000003 s. The parameters of the perturbed motion have been determined: the motion of periastron ω = 0. °315 ± 0. °005/ year, and the derivative of the period of the binary system Ṗ = (-1.66 ± 0.11) × 10-14 s/s = (-0.524 ± 0.038) µs/year. The estimated time scale for the decay of the PSR 0655+64 system is (1.7 ± 0.1) × 1011 yrs.

В течение 2010–2012 гг. на радиотелескопе БСА Пущинской радиоастрономической обсерватории АКЦ ФИАН на частоте МГц проведены наблюдения RRAT-пульсаров J0627 16, J0628 09, J1819-1458, J1826-1419, J1839-01, J1840-1419, J1846-0257, J1848-12, J1850 15, J1854 0306, J1919 06, J1913 1330, J1919 17, J1946 24, J2033 00, наблюдавшихся ранее на 64-м телескопе в Парксе (Австралия) и на 300-м радиотелескопе в Аресибо (Пуэрто-Рико) на частоте 1400 МГц. Характерной особенностью этих пульсаров является спорадическое радиоизлучение в редкие активные моменты и отсутствие радиоизлучения в течение длительного времени. За время наблюдений в ПРАО заметной вспышечной активности указанных пульсаров обнаружено не было. Однако обработка наблюдений с помощью алгоритма быстрого суммирования с учетом известных данных о мере дисперсии и периоде пульсара показала, что даже в пассивные интервалы времени большинство исследовавшихся пульсаров генерируют слабые радиоимпульсы с периодом, соответствующим периоду радиоизлучения спорадических импульсов RRAT-пульсаров, наблюдаемых в активные моменты. Плотность потока этого радиоизлучения даже на низкой частоте МГц в максимуме импульса не превышает мЯн. Это значительно затрудняет регистрацию радиоизлучения RRAT-пульсаров на высоких частотах, так как плотность потока радиоизлучения RRAT-пульсаров уменьшается с ростом частоты.

The new modern and reliable data storage system was acquired in 2010 in order to develop internal telecommunication resources of the Observatory. The system is designed for store large amounts of observation data obtained from the three radio-astronomy complexes (PT-22, DKR-1000 and BSA). The digital switching system - "Elcom" is installed in the Pushchino Radio Astronomy Observatory to ensure the observatory by phone communications. The phone communication between buildings of the observatory carried out over fiber-optic data links by using the ip-telephony. The direct optical channel from tracking station RT-22 in Pushchino to Moscow processing center has been created and put into operation to transfer large amounts of data at the final stage of the establishment of ground infrastructure for the international space project "Radioastron". A separate backup system for processing and storing data is organized in Pushchino Radio Astronomy Observatory to eliminate data loss during communication sessions with the Space Telescope.

On PRAO’s web-site we have for several years been developing a database of the major and most important astronomical catalogs most frequently used by radio astronomers. These are survey catalogs of radio sources observed on various radio frequencies (and also frequencies of other spectrums), catalogs of major heavenly objects studied in radio astronomy, etc. The astronomical catalogs data is operating in on-line mode on the site called “Radio-astronomer’s working environment”, http://astro.prao.ru/db/. It already contains some tens of the major astronomical catalogs. Starting in 2011 the database has been actively equipped with means of graphical visualisation of the data and cross-analysis of the catalogs among themselves. These means will serve as the base for statistical processing and cross-analysis of various astronomical catalogs. For example, catalogs of radio-sources on various frequencies can be widely used in further theoretical and experimental research of properties of both extragalactic radiation sources and objects in our own Galaxy. Statistical cross-analysis of the data from various catalogs can be used both for research of properties of separate objects and for the statistical analysis of properties of various classes of objects. It can also be used for research of properties of the catalog data like completeness, reliability, calibration of catalogs etc. For the tasks at hand we are developing tools for graphic representation of the data from several catalogs within a chosen sector on the sky; representation of the data and the statistical analysis of the main parameters of each catalog; and statistics of cross-identifications of the catalogs selected by the user.

The Radio Astronomy Data Center (RADC) are developed at PRAO ASC LPI in last some years. It consists from: a) the database of most important for radio astronomers astronomical catalogs; b) the database of observational data of Pushchino Radio Astronomy Observatory. The database of astronomical catalogs http://astro.prao.ru/db/ contains few tens of most important catalogs for planning radio astronomy observations. Since 2011 a database of astronomical catalogs actively equipped with graphical tools for data visualization and cross-analysis of catalogues between one with other. The observation database http://observations.prao.ru/ is collected observational data from base observatory instruments and radio telescopes. This database provides access to observation instruments and telescopes descriptions, techniques of making data samples per instruments, information about types of observations, observers and dates of observations and so on.

Development of fundamental science today depends largely on the availability of modern computing and communications resources. Pushchino Research Center consists of 8 institutes and 2 branches of RAS, including specialized research facilities and system of data processing and storage, as well as a number of other objects. And all these objects combined into a single local area network built on fiber optical channels and on the signal topology named "star". The main management servers that organize routing and provide the necessary Internet services (mail, web servers, databases, etc.) are located in the center of the network at the Institute of Mathematical Problems of Biology. Servers work under control of virtualization system. The network of Pushchino Research Center includes a high-performance cluster with total performance about 830 gigaflops, designed for resource-intensive computing tasks of broad range basic research. A separate external optical communication channel with data rate 1 Gbit/s created in the Pushchino Radio Astronomy Observatory in the framework of international project of space radio telescope "Radioastron" together with the company «Stack Group».

We have detected the new pulsar PSR J2225+35, which displays the properties of the new class of radio sources “Rotating Radio Transients” (RRATs). RRATs are distinguished by isolated bursts of radio emission and long quiet periods. Throughout 45 observations with a total duration of about 3 hr, only two bursts of radio emission lasting a total of about 10 min were detected in two observations. The temporal and frequency delay of the pulses corresponds to the dispersion measure DM = 51.8 pc/cm 3 and the distance d = 3.05 kpc. The period of the pulses is P = 0.94 s. The emission is polarized, with the rotation measure being RM = 49.8 rad/m 2 .
