... Jitter is usually very small in magnitude and random in effect, and is not expected to lead to systematic throughput changes. ... However, such a change should lead to an obvious decline in the strength of the comparison lines at one end of the spectrum relative to the other and not an overall decline in counts. No such effect is seen (the counts decline evenly from one end of the spectrum to the other). ... The value changes steadily, but not by enough to account for the changes in counts seen. ...

This is a copy of a Press Release from E.S.O. The most recent ESO observations of bright Comet Hyakutake have shown rapid changes in the innermost coma, within a few hundred kilometres from the cometary nucleus. This result has only become possible because of the unusual combination of a bright comet being near the Earth, together with the excellent imaging quality of the ESO 3.5-metre New Technology Telescope (NTT). ...

... Ceresт?? bright spots show unexpected changes . ... CERES | ... Observations made using the HARPS spectrograph at the European Southern Observatory s (ESO) La Silla Observatory in Chile have revealed unexpected changes in the bright spots on the dwarf planet Ceres. Although Ceres appears as little more than a point of light from Earth, careful study of its light shows not only the changes expected as Ceres rotates, but also that the spots brighten during the day and also show other variations. ...

Perhaps the greatest theoretical achievement of physics in the 19th century was the discovery of electromagnetic waves. ... It is possible to use this to define a unit of electric charge, as the charge which repels a similar charge at a distance of, say, 1 meter, with a force of unit strength (actual formulas make this precise). ... But "field" originally only meant the force a magnet or an electric charge could expect at a point in space, if it were placed there. ...

Figure 6. The squares show the telescope defocus data from August 15 (Figure 5) plotted as a function of time. For the defocus data the y-axis is in units of ?m. The circles show the telescope altitude in degrees as a function of time. As expected from the good linear correlation seen in Figure 5, the data very much look like they are driven by altitude changes. ... Second, notice that the defocus data consists of pairs of points which were taken at nearly the same telescope altitude. ...

... The system temperature versus turret position has shown a bump (increase) for some receivers at the turret focal position. The receivers that had this increase also had platform focus curves where the platform focus position was lower than expected (or the horn was too high). ... After the focus change a 20 deg amplitude sine wave was done using the turret about the turret focus position. ... The plot shows the difference in Tsys versus turret position before and after the focus change. ...
