The display stretches across Canada; just below it, in the middle of the picture, are the lights of Chicago, next to Lake Michigan. ... The Canadian scientific satellite Isis-2 (1971) carried an auroral imaging camera and discovered the diffuse aurora, a broad ribbon around the auroral oval, too spread-out to be noticed from the ground. ... Auroral Acceleration . ...

6. http://www.mso.anu.edu.au/seminars/abstracts/20150508-1400.html
It is possible to piece together the processes that have shaped the observed characteristics of a galaxy by studying its stars in detail. The Large Magellanic Cloud (LMC) is an excellent candidate for this type of study because of its favourable viewing angle and ongoing star formation. I present the results of high-resolution VLT/FLAMES observations of ~80 red giant stars around star cluster NGC 1846, located in the disc of the LMC. ...

Fitting the observed dependence includes calculations of the polarization cross-sections averaged over particles orientation and size distribution, their normalization and the comparison of obtained dependencies with Serkowski's curve representing observational data for a chosen star. ... Variations of the polarization factors with wavelength are shown in Fig. 16 for homogeneous spheroidal particles with PF orientation. ... The distinction between prolate and oblate spheroids is also clearly seen. ...

8. Period Criteria
... Actual stars are expected to be more complicated than these simulations. ... The spot may be entirely visible most of the time (one would observe a prolonged flux minimum low), and then part of it may disappear over the horizon briefly and then return (slow rise and then fall back to constant level). ... With the set of observations taken here, I have information available from several comparison stars and color information. ... The period found must be consistent with the data from any given night....

12. Getting the observations
Next: Reducing the observations Up: PEPSYS general photometry Previous: Influencing the plan . ... If the telescope and instrumentation are unfamiliar to you, you may have trouble keeping to the schedule for the first night or two, so try to work with a previous observer on the equipment for a night or two of training before your observing run. If you fall behind, try to keep as many low-altitude observations of extinction stars as you can, and drop some circumzenithal ones if necessary. ...

15. What is Redshift? (2dF QSO Redshift Survey - 2QZ)
... Under certain conditions, like those in the nucleus of a QSO, all atoms can be made to emit light at particular wavelengths. ... If that source is approaching the observer, the wave is squashed up onto itself making the wavelength shorter. ... This is redshift. ... You can see how the section of the QSO spectrum which we observe changes with redshift. ... We then see how far we had to slide the observed spectrum along the scale to make it match and that is the objects redshift. ... The 2QZ team . ...

... We also take care to characterise the flat fields, especially their colour dependence, to very high precision which enables high precision photometry even without autoguiding. ... The Blue Diamond Effect The blue diamond effect is caused by surface imperfections on the silicon chip introduced during manufacture, resulting in a repeated large scale pattern in the flat field at blue wavelengths. ... We can remove the blue diamond by using a colour appropriate flat field produced in the lab. ...
