... Bad Astronomy . ... I think I will break from my usual format of Bad Astronomy/ Good Astronomy by saying that the way we define seasons currently is not strictly bad, but I feel (in my opinion!) that it could be better. The definition of when the seasons begin is at the moment of solstice or equinox; that is, winter (in the north) starts on December 22 nd and summer starts on June 22 nd . ... Now imagine breaking up the Sun's 46 degree up-and-down yearly swing into 1 day intervals. ...

It could be that SETI signals have arrived at the Earth, but are lower then the noise level, and our receivers cannot detect them. ... Fig. ... It follows that two zones form around the star with civilization X: "Zone Yes", where its SETI signal can be detected, and "Zone No", where its signals are hidden by noise (Fig. ... In practice, it is more efficient to use a time factor, since the problem of SETI contact does not limit the duration of the signal element and semantic text. ...

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. ...
