SpaceWeather.com: Aurora Mega-Gallery
We are indeed thankful to Dr. Tony Phillips [webmaster of Spaceweather.com] and the several contributors to the website, for their tireless work in contributing their aurora ( luminous atmospheric phenomena appearing as streamers or bands of light sometimes visible in the night sky in northern or southern regions of the earth. It is thought to be caused by charged particles from the sun entering the earth's magnetic field and stimulating molecules in the atmosphere) photos for our viewing.
