in the southern side of the sky at 8-9 in the night(here in India) we can see a 
star which is seen displaying a varirty of colours which are constantly 
changing. when i I referred to star charts i assumed that it was Canopus. i 
don't understand why does that particular star changes its colors while others 
display a particular one.
