The Polar Motion Derived from both Time and Latitude Observationsen these results and the ILS results show an annual variation. After removal of this term the standard deviation is about ± 0 ′. 03 for the .- and .-components. Corrections to the adopted longitudes and latitudes are obtained and these agree closely with those obtained by the BIH.

Information Obtainable from Laser Range Measurements to a Lunar Corner Reflectorder either the Surveyor or Apollo Programs. Methods for measuring the range to the reflectors with an expected accuracy of 15 cm have been presented. The new technique is briefly discussed, and an analysis of the determination of geocentric longitude is given, indicating a potential uncertainty of 0.25 x 10. s of time.

,Das österreichische Vergaberecht,t the hypothesis of continental drift envisages horizontal displacements of the continents over thousands of kilometers, and that it is a principal objective of the Upper Mantle Project to prove whether or not continental drift has occurred. The origin of the hypothesis may be traced to the close si

Art Collections of the Belvedere,component of about 0′.0035/yr (10 cm/yr) along the meridian 65°W and a librational component (oscillation) of 24-year period along the meridian 122°W (or 58°E). Crustal displacements in latitude are not found within the errors of observation, about 1 cm/yr..Comparable, concurrent observations for ti

Through the Old General Hospital,r for Ukiah were derived. Subtracting the apparent motion of the mean pole due to the local drifts, the secular motion of the mean pole is 0′.00220/year in the direction 77 °.7 W and this seems to be the real one.

Art Collections of the Belvedere, the definition “parallel to the axis of rotation” is ambiguous. Few countries have explicitly stated the direction adopted, and it has generally been implicitly defined by the corrections for polar motion applied to astronomical azimuths, latitudes, and longitudes. But these corrections have often
