Hubble Space Telescope image of Jupiter showing the impact site of comet Shoemaker-Levy 9 fragment G. The image was taken on 18 July 1994 about an hour and 45 minutes after the impact. The impact site is the dark round area below and right of the center of the frame, at about 45 S latitude. ... The fragments of Shoemaker-Levy 9 impacted Jupiter at about 60 km/s and left traces in the atmosphere which could be observed for many weeks. ... Central Latitude/Longitude (deg): N/A . ...

... Let us first find out which way -- rise in spectral resolution with some loss in the S/N ratio or increase in the S/N ratio with a fixed spectral resolution -- is better for the purpose of reduction of equivalent width determination errors. ... N -- number of counts for 1 ? ... line equivalent width, . ... Thus if the spectral resolution is managed to be increased (i.e. to decrease )without loss in the number of counts falling at 1 ?, the equivalent width measurement error is then proportional to . ...

Static Fourier spectrometers are often used for spectral measurements of the ionosphere emissions. There are two main advantages of Fourier spectrometers (FS) - large geometric factor and high spectral resolution; these parameters are two orders better than for grating spectral instruments. ... In scanning Fourier spectrometer optical and electric modulation of signal is used to avoid this problem, for static Fourier spectrometer there are no such ways. ...
