Earth's atmosphere, interacting with light, provides a wonderful

outdoor laboratory where we can see the rainbow, sun-dogs, sun

pillars, the glory, mirages and the green flash. These optical

delights, and others, including why the sky is blue, will be

described, using illustrations and some demonstrations. Our goal in

this talk will be to enthuse and to encourage you to take the time to

look up and observe these phenomena with added understanding.
