Sky Watcher's Field Cheat Sheet: Clouds, Light & Sky

A printable field reference for curious teens and adults who look up and wonder what they are seeing. Inside: the ten basic cloud types with height levels and looks, a short card on why the sky is blue and sunsets are red, a table of rainbows, halos, sun dogs, coronas and crepuscular rays, notes on contrails and fog, and a reusable sky-spotting log. It runs about 8 pages and prints on A4 and US Letter. Every fact is tied to a listed source such as NOAA, NASA or the UK Met Office, and settled science is separated from open questions.
