On 07apr08 at 21:30 tiedown 8 stopped moving. ... The plots show the tiedown motions during td8 failure (.ps) ( .pdf ). ... Velocity feedback. This is a read back of the DtoA voltage that is sent to the motor amplifier. ... Page 1: 07apr08 20 to 22 hours shows when td 8 stopped moving. ... The td8 commanded velocity is 0 implying that the td8 was not asked to move. ... td8 remained stationary, td4,12 where moving. td8 commaned velocity was 0 so it was never being requested to move. ...

... HST . Identification of Erroneous Doppler Compensation for Moving Targets . ... Data . ... HST Overview . ... The problem concerns only GHRS observations of moving targets; fixed target observations are not affected. The problem concerns how the onboard doppler compensation is applied to observations of moving targets. ... These onboard corrections cannot be removed after the fact except as an overall shift of the spectrum, but the net doppler compensation applied is stored in the data header. ...

... For moving objects such as asteroids, comets, or planets, it is useful to include ephemeris information, both to provide predicted coordinates for planning observations, and to allow accurate airmass calculations in the reductions. ... These times can be given either as Modified Julian Dates ( ), or as ordinary date strings like 1995 Jan 23.0 . To allow good interpolation, include two ephemeris entries before and two after the interval of observations. ... UT date --- column label: DATE . ...

... Girls from Scoil Rince Emain Macha and choreographer Lorraine Scallon provided a moving astronomy-inspired dance at the opening of the John Hewitt Summer School at the Market Place Theatre, Armagh, on Monday 26 July. The highly acclaimed performance was part ofб "OASES", a cross-border and cross-community initiative that uses science and the arts to bring people from different backgrounds and different communities together. ... Nowadays Science and Arts are completely separate worlds. ...

Astronomy suffers from the `Static Illusion' - because astronomical changes usually occur over intervals much longer than a human lifetime they appear static. This illusion affects our understanding of how astronomical objects work. ... Observations at the 1/10th arcsecond level with HST and near-infrared adaptive optics on ground based telescopes are beginning to create movies of `astronomy in motion'. ... Proto-star HH-30 expanding jet HST.. Young binary, XZ Tau, expanding `bubbles' HST.. ...

... Up: Data Analysis and Processing Techniques . ... Also, a method for quality control of CCD observations is suggested. ... Everyone who observes a celestial object using a CCD detects moving celestial objects as a ``by product''. ... We hope that our investigations may be useful for near-Earth space control and also for searches of the moving celestial objects through analysis of old and new CCD frames obtained at any amateur or professional astronomical observatory. ...

It was delivered to a concrete slab and a layer of 2x6s set on top. We then winched the top onto the bed, raised to the level of the 2x6s, and slid it off onto the base with the 2x6s in between. ... www.astronomy.net . ...

... To derive the motion of a penny dropped inside an airliner moving at 600 miles/hr (about 1000 km/hr)--should we calculate it with respect to the interior of the airliner, or with respect to the ground? ... And if a similar penny is let go inside an orbiting spaceship--should its motion be calculated relative to the interior of the spaceship, or relative to the Earth outside? ... Each such choice is known as a frame of reference . Some possible frames are -- the interior of the airliner, . ...

... When the cursor is moved across the image (using the left-mouse button) a profile, from the cursor-position upwards to the height of the spectrum extraction-region height, is drawn at the bottom of the image. A new spectrum is selected by centering the cursor (either by moving the mouse or by using the arrow keys on the right of the key-board) over the approximate centre of the corresponding zeroth-order feature and either clicking the left-mouse button or hitting the return key. ...

Turning the Camera Skyward . A reconfigured camera can take wide-field exposures of astronomical objects (constellations, the Milky Way, zodiacal light, moving artificial satellites, meteor showers, variable stars, etc.) to reveal much fainter objects and structures than seen by naked eye. ... This picture reveals objects more than 2.5 times fainter than can be seen by the naked eye, including not only stars but also the Orion nebula (M42), where new stars are being born. ...
