Kinematically the PMSand Pleiades-type stars appear to form a group with space velocitiesclose to the Castor moving group but clearly distinct from the on observations collected at the German-Spanish AstronomicalCentre, Calar Alto, operated by the Max-Planck-Institut fürAstronomie, Heidelberg, jointly with the Spanish. 46 Boötis is a binary star system in the northern constellation of Boötes, located mid-way between α Coronae Borealis and ε Boötis. It has the Bayer designation b Boötis; 46 Boötis is the Flamsteed designation. The system lies light years away from the Sun based on parallax, and is visible to the naked eye as a faint, orange-hued star with a combined apparent visual magnitude of Date and Time of start and end of observation (local time or UT) Location of observation (Place Name, Latitude, Longitude, and Elevation) Percent cloudy at each hour during the observing period; Direction faced and altitude observed and time of any changes; Sky conditions at each hour during the observing period (Seeing and Transparency).

The effects of some short-period tidal and nutational terms in the observations of the Herstmonceux PZT have been re-examined using observations that O’Hora N.P.J., Griffin S.F. () Short-Period Terms in Time and Latitude Observations Made with the Herstmonceux Photographic Zenith Tube.
Buy this book on publisher's site; Reprints Cited by: 2. The latitude and time observations of the Herstmonceux and Ottawa PZT’s for the years – have been jointly analysed to discover whether discontinuities or other systematic changes in the results can be associated with the incidence of major : N.
O’Hora, D. Thomas. Numerical values in time and latitude for these terms to he expected at the Tokyo PZT are also given. From the data of time observations obtained by the Tokyo PZT during the past 15 years, amplitudes of the terms, cos(α–2L α) and sin(2α–2L α) in time, are obtained as + and ms, : Shigetaka Iijima, Shigeru Fujii, Yukio Niimi.
The Mizusawa PZT (Photographic Zenith Tube) was moved from its semibasement location (the second PZT observation room) to a location m above ground level (the third PZT observation room) in order to avoid the effects of temperature variations near the ground during observations.
Some provisions are made for prevention of heat flow from the ground and for radiation by: 1. Excerpt from Astronomy, Determination of Time, Longitude, Latitude, and Azimuth From time to time during many years publications have been issued describing the.

Djurovic D. () Polar Coordinates and UT1 — UTC from PZT Observations. In: McCarthy D.D., Pilkington J.D.H. (eds) Time and the Earth’s Rotation. International Astronomical Union (Symposium No, Proceedings of Pzt Observations of Time and Latitude book 82nd Symposium of the International Astronomical Union Held in San Fernando, Spain, 8–12 May, ), vol Residuals in the latitude observations by the US Naval Observatory at Washingtonin the years – are analyzed.
They are shown to be correlated with the southern oscillation index (SOI) in the interannual frequency range, with correlation coefficients as high as – or greater.
The PZT residuals lag behind the SOI by some 2 years. It is suggested that catalog errors and the annual part of polar motion cannot be completely separated from each other on the basis of only PZT observations.
Most of the existing discrepancy between the polar motions in time and in latitude observations in fact can be attributed to the errors in the current PZT star catalogs; this is obtained from a comparison of the positions between AGK3R.
Here, we use the latitude part of ten Photographic Zenith Tubes – PZT data (more than million observations made at 6 observatories during the time interval –), and combine them with the Hipparcos catalogue ones, with suitable weights, in order to check the proper motions in declination for common PZT/Hipparcos stars (and.
IAU Symposium No. 82, "Time and the Earth's Rotation", met to discuss modern research in the field of the rotation of the Earth with particu lar emphasis on the role of new observational techniques in this work.
The use of these techniques has prompted a new look at the definitions of the. This annual report consists of two parts. The first part shows the results of the time services, i.e., time and latitude observations with the PZT, comparison of UTC(NAOM) with the Loran C and GPS (Global Positioning System), and comparison of the atomic clocks at the Mizusawa Astrogeodynamics Observatory.

In this paper we analyse the observational data obtained by the Chinese-made PZT in the two periods Feb – May and Dec – March.
The. We present the results of optical photometric observations of three extreme TeV blazars, 1ES $+$, 1ES $+$, and 1ES $+$, taken with two telescopes ( m.
The latitude part of ten Photographic Zenith Tubes (PZT data made at 6 observatories) were useful to combine them with the Hipparcos data and to construct the PZT catalogue with µ δ for The theory that the eastern and western hemispheres are drifting apart was expounded in particular by A.
Wegener. Modern geophysical theories seek to explain paleomagnetic observations by - suming that two things have occurred in the past: (a) large-scale polar wandering, and (b) continental drift. Yet it is stated in the IAU Meeting Report  that there is good agreement between the observational results of the old and new PZT at Mizusawa.

On some of my other web pages there's information about the PZT but in reference to it's use to determine the time based on the Earth's rotation. But in the D.O.C. U.S. Coast and Geodetic Survey Special Publication No. 27, "Latitude Observations with Photographic Zenith Tube at Gaithersburg, MD.".
Here, we use the latitude part of ten Photographic Zenith Tubes – PZT data (more than million observations made at 6 observatories during the time interval –), and combine them.
Astronomical time-latitude observations are characterised by their high accuracy and systematic nature. In the time-latitude service we have accumulated a wealth of continuously recorded data spanning many years.
So, we can hope to find some.

The accuracy of latitude and Universal time determination from the optical astrometry observations, obtained during the last century in programs of monitoring Earth orientation, strongly depends. The Earth orientation parameters, based on optical astrometry observations of latitude/universal time variations and the HIPPARCOS Catalogue, covering the interval -were determined.

Time to PZT for all nest configurations during inclement weather conditions (T a = −2°C and u = 10 m/s) ranged from minutes to minutes (>75% difference), while estimates of time to PZT during mild weather (T a = 9°C and u = 1 m/s) ranged from minutes to minutes (∼10%.
The current equation of time is ( minutes 45 seconds), so subtracting a negative number means that clock time is about 13 minutes later than local solar time. You also need to correct for your longitude east or west of your standard time zone's central meridian. Dasen was influential in education wmte, august, vaxjo, sweden, pp.

The latitude of the South Pole is 90° S, and the latitude of the North Pole is 90° N. Locating Places in the Sky. Positions in the sky are measured in a way that is very similar to the way we measure positions on the surface of Earth.
Instead of latitude and longitude, however, astronomers use coordinates called declination and right. The link between longitude & time. Each 15° of longitude is equivalent to a difference in time of one hour. In theory then, in order to find out how far east or west he was from his homeland, all a sailor had to do was determine his local time from observations of the Sun or stars and compare it with the time back home at the same moment.

This is a colorful and interactive geography activity for young explorers!. The Antarctic Circle on the other hand, is the latitude 66° 34′ south. Any locations falling south of this latitude are said to be in the Antarctic Circle. Places in both the Arctic and Antarctic circles experience the Midnight Sun and polar night.
The latitude 23° 26′ North is also known as the Tropic of Cancer. It marks the northern.Latitude was not much of a problem. All the sailor had to do was measure the altitude of the sun at noon. This varies with latitude (and with the time of the year), and a simple geometric calculation allows the latitude to be computed from the noon altitude on any given day of the year.HD Observation data Epoch J Equinox J; Constellation: Boötes: Right ascension 14 h 34 m s: Declination +36° 37′ ″ Apparent magnitude (V): Characteristics.
