Figure 4. This shows the axial sag of encoder A as a function of telescope elevation angle. The circles show data collected while the elevation angle was increasing from the horizon (0 degrees) towards the zenith (90 degrees) and the squares show data collected in the opposite direction. ... The differences between the values of m2 measured when the elevation angle is increasing and that measured when the elevation angles are decreasing is real. ...

... Moon Phase below . ... ARTICLE: Why the moon always shows us the same face . ... Before you continue reading, you should know that this was not always the case, i.e. the Moon once was rotating with respect to the Earth, so that on every night a terrestrial observer (if there was one, because this was long, long before mankind appeared on our planet, and even before any major animals had appeared) saw another face of the Moon. ... Figure 1 (not to scale) shows how we can imagine the system Earth-Moon...

This page is devoted to information on Supernova 1999an in IC 755 . Basic information on this SN, including the last reported brightness, on this Supernova can be found on the main supernova page. Information on the original web pages for many of these images can be found on the Supernova links web page. 1999an got lost in the glow of IC 755. It originally shows up on an image at BAO on Jan 22nd, and also showed up on an image taken by Mike Schwartz on Feb 8th. ... 3/14.2/1999 . ...

... The Palomar Testbed Interferometer (PTI) is a 110-meter baseline K-Band infrared interferometer located at Palomar Mountain, California. In 1999 an effort was started to provide more observer-friendly observation planning and monitoring tools, such as might be used in NASA interferometer missions. This session illustrates how these prototype tools aid in the observation of spectroscopic binary stars. ... In 1999 an effort was undertaken to prototype mission operations support tools at PTI. ...

... The main task of this Working Group has been to review the state-of-theart knowledge of the Milky Way galaxy, to identify the future challenges, and to propose which tools (in terms of facilities, infrastructures, instruments, science policies) would be needed to successfully tackle and solve the remaining open questions. ... This Working Group has made recommendations that would allow dissecting our backyard laboratory, the Galaxy, even further. ...

SLIDE 1 Coherent beam­beam e#ects study. ... He has shown that a finite length (in other words equal to # # ) of colliding bunches can lead to the coupling of synchro­betatron modes in the beam­beam system, and thus a head­tail type instability of colliding bunches may arise. ... These modes have been observed in di#erent machines. ... SLIDE 5 Figure shows the dependence of the measured and calculated synchro­betatron mode tunes on the beam current for equal electron and positron bunch intensities. ...

... Under certain conditions, like those in the nucleus of a QSO, all atoms can be made to emit light at particular wavelengths. ... If that source is approaching the observer, the wave is squashed up onto itself making the wavelength shorter. ... This is redshift. ... You can see how the section of the QSO spectrum which we observe changes with redshift. ... We then see how far we had to slide the observed spectrum along the scale to make it match and that is the objects redshift. ... The 2QZ team . ...
