Parameters of the Infrasound Signal Generated by a Meteoroid over Indonesia on October 8, 2009
Kinematics and Physics of Celestial Bodies - - 2018
L. F. Chernogor, M. B. Shevelev
The basic parameters (delay time, celerity, duration, oscillation period, and amplitude) of the infrasound signal recorded by 17 stations are statistically analyzed as a function of the horizontal distance between the Indonesian superbolide total radiated energy and the infrasound station location. Fitting dependences of signal parameters on distance are given. Correlation diagrams are constructed...... hiện toàn bộ
Analyzing the Time Series of Coordinates from the GNSS Station Chernihiv (CNIV)
Kinematics and Physics of Celestial Bodies - Tập 37 - Trang 212-219 - 2021
N. I. Ishchuk, M. V. Ishchenko, Yu. I. Velikodsky
Observations at permanent stations of the Global Navigation Satellite System (GNSS) are directly related to global and local movements of the Earth’s crust and are also affected by various factors, such as the multipath effect and radio noise in the signal. Currently, the influence of such effects can be analyzed and excluded from further processing of GNSS observations. However, there are a numbe...... hiện toàn bộ
Convection Effect in the Surface Atmosphere of Solar Eclipses of March 20, 2015, and June 10, 2021
Kinematics and Physics of Celestial Bodies - Tập 37 - Trang 284-292 - 2021
L. F. Chernogor
The parameters of geophysical fields and numerous parameters of the Earth–atmosphere–ionosphere–magnetosphere system significantly change during a solar eclipse (SE). In particular, the planet surface temperature decreases, the convection and turbulent processes slow down, and the air temperature near the ground reduces. The inhomogeneous structure of the surface air layer notably changes, and the...... hiện toàn bộ
Kết quả của chiến dịch đo đạc địa lý thứ ba trong khu vực thử nghiệm địa động lực học địa phương của MAO NAS Ukraina Dịch bởi AI
Kinematics and Physics of Celestial Bodies - Tập 24 - Trang 309-316 - 2008
A. N. Samoilenko, A. V. Adamenko, O. V. Bolotina, V. V. Zayets, O. A. Khoda
Các tọa độ chính xác cao của các điểm tham chiếu (giảm) của các trạm nằm trong khu vực địa động lực học của MAO NAS Ukraina đã được xác định trong hệ tọa độ địa phương topocentric. Các mối liên kết địa lý địa phương (độ lệch) giữa các điểm tham chiếu của trạm GPS “Kiev/Goloseev” và trạm định vị laser vệ tinh “Goloseev-Kiev” có độ dài lần lượt là 100.2358 m, -11.0398 m, -85.8256 m trên trục X, Y, Z...... hiện toàn bộ
Compiled catalog of the proper motions and infrared photometry of stars at the north Galactic pole
Kinematics and Physics of Celestial Bodies - Tập 24 - Trang 176-180 - 2008
S. P. Rybka, A. I. Yatsenko
We describe the procedure we used to compile a catalog of the proper motions of 23 633 stars in the sky area covering about 700 square degrees at the north Galactic pole. The compiled catalog combines the data from the UCAC2, Tycho-2, and FONAC catalogs for stars down to V ∼ 14 m in this sky area. In addition to proper motions, the catalog also contains the near-...... hiện toàn bộ
On the modern approach to the problem of detecting hazardous celestial bodies
Kinematics and Physics of Celestial Bodies - Tập 32 - Trang 218-222 - 2016
B. M. Shustov
The problem of detecting dangerous (in the sense of a collision with the Earth) celestial bodies of natural origin and the modern concept of building a system of detection of such bodies are discussed. The concept includes two items: remote detection of large (>50 m) hazardous objects providing warning time of several tens of days, which is sufficient to allow the active counteraction and detectio...... hiện toàn bộ
Influence of the random refraction of radio waves in the corona on the properties of solar noise storms
Kinematics and Physics of Celestial Bodies - Tập 23 - Trang 191-195 - 2007
Yu. F. Yurovskii
Scattering of radio waves on irregularities in the coronal electron density is inevitably accompanied by variations of scattered signal intensity. According to the probability theory, the scattered signal intensity distribution is described by an exponential law. The empirical intensity distribution in the majority of the observed noise storms is also adequately described by an exponential law, an...... hiện toàn bộ
Compiling catalogs of stellar coordinates and proper motions via coprocessing of archival photographic and modern CCD observations
Kinematics and Physics of Celestial Bodies - Tập 30 - Trang 296-303 - 2014
Yu. I. Protsyuk, M. V. Martynov, A. E. Mazhaev, O. E. Kovylianska, S. V. Protsyuk, V. N. Andruk
A catalog of positions and proper motions of stars in the fields around open clusters was compiled at the Research Institute—Nikolaev Astronomical Observatory (NAO) with the use of the results of photographic observations conducted in the 20th century (at the NAO zonal astrograph with D = 11.6 cm and F = 2.04 m) and modern CCD observations performed with the Mobitel NAO telescope (D = 50 cm and F ...... hiện toàn bộ
Prediction for the amplitude of solar cycle 24 from the pattern of activity near the cycle minimum
Kinematics and Physics of Celestial Bodies - Tập 29 - Trang 37-43 - 2013
M. I. Pishkalo
Correlations are investigated between the pattern of solar activity described by the smoothed monthly relative sunspot numbers (Wolf numbers) near the minimum of a solar cycle and the cycle amplitude. The closest correlation is found between the amplitude of a solar cycle and the sum of the decrease in activity over two years prior to the cycle minimum and the increase in activity over two years a...... hiện toàn bộ
Spectrum of comet C/2009 P1 (Garradd) in the optical wavelength range
Kinematics and Physics of Celestial Bodies - Tập 30 - Trang 276-287 - 2014
O. S. Shubina, P. P. Korsun, V. L. Afanasiev
Moderate-resolution spectra of comet C/2009 P1 (Garradd) in the wavelength range from 380 to 540 nm have been analyzed. The spectra were acquired, when the comet was at the distances 1.96 and 1.36 AU from the Sun and the Earth, respectively. The observations were fulfilled in the prime focus of the 6-m BTA telescope (Special Astrophysical Observatory, Russian Academy of Sciences) with the use of t...... hiện toàn bộ
