... Mercury well placed in evening sky: Mercury, the elusive€аinnermost planet, will reveal itself in the evening twilight in late April and early May. It can be fairly bright, but is always difficult to see as it never moves far from the Sun in the sky, and so can only be seen low down in the evening or morning twilight. €а€а You could look for it with good binoculars€аas early as 25 April, when it will be bright, but very low down in the WNW sky€аby the time the sky is dark enough to see it. ...

... Bad Astronomy . ... Bad Astronomy : The Moon appears larger on the horizon than overhead because you are comparing it to foreground objects. Good astronomy : The Moon does appear larger on the horizon, but it is because of the way we perceive the sky. ... The most common misconception is that it is because you are unconsciously comparing the Moon to foreground objects like trees and houses, or even the horizon itself, and that makes the Moon look bigger than when it is all alone in the sky. ...

... This document and the attached postscript figure document an analysis that I did to determine the optimum midpoint and required ranges for both the rotator and azimuth for the 2.5 M telescope. ... I simulate a series of drift scans on the sky for tracks that cover the northern survey area. These tracks cover the range in survey latitude of -60 to +60 degrees, spaced by 10 degrees. ... Along each track the azimuth, elevation, and position angle of the CCD is computed at 1 minute intervals. ...

Radio Interferometry Principles . Radio Interferometry Signal Processing . ... A radio interferometer consists of a pair of directional antennas that are tuned to receive radio emissions from a source in a desired RF band. ... The antennas are pointed at the radio source of interest and are set up to receive the signal and process it into a form suitable for transmission to the correlator. ... In connected element interferometry, the digital signal goes directly to the correlator. ...
