Sky watching

Auroras:  When do auroras occur?
Ball lightning:  I was wondering if Ball Lightning exists. What do you know about it? Where does it happen? When and why?
Blue Ice: why is some ice blue?
Blue jet:  One night I was watching a storm and the lightning turned blue. How did that happen?
Blue mountains:  Why do distant mountains look blue?
Blue Skies: why is the sky blue?
Bluer on top: why is the zenith sky bluer than the horizon sky?
Clouds:  When a thunderstorm approaches, the sky turns black. Why? If it’s filling with rain, it should be white, right? What causes the black or gray in clouds?
Clouds:  Why do clouds "stick together"? I realize that clouds are condensation of evaporated moisture from the ground, but why are they "puffy"? Why don't they diffuse uniformly into the atmosphere at the altitude in which the moisture condenses, i.e. more of a uniform fog than a puffy cloud?
Cold temperatures:   Why is it colder in the mountains?
Contrails: Why do jets leave white streaks in the sky?
Green Flash: why does the Sun turn green just before it sets?
Green flash, photo: How do you take a picture of a green flash?
Green flash, at the poles: Do they have green flashes at the South Pole?
Horizon:  If I am on the ground, how many miles away is the horizon?
Lightning: does lightning strike Mount Everest?
Lightning:  If lightning strikes the ocean, do the marine animals get hurt or killed?
Lightning:  Lighting is supposed be three times hotter than the sun. Since the lighting flashes are closer than the sun how come we don’t feel the heat when it flashes?
Lightning:  One night I was watching a storm and the lightning turned blue. How did that happen?
Lightning:  My kids were wondering how wide and long lighting can be.
Lightning:  Where in the world do the most lightning strikes occur?
Lightning:  What causes lightning?
Lightning:  Does lightning strike indoor swimming pools? Has anyone ever been hurt or killed?

St. Elmo's fire:  Why would a lightning-struck tree glow after being hit? It is not on fire and does not give off heat, but gives off a very visible glow.
Meteors: When is the once-in-a-lifetime meteor shower (Leonids) occurring?
Meteor showers: Which day (18 or 19 November) will I be able to see a good meteor shower (Leonids) from Mumbai, India?
Orange sky:  Why does the sky appear orangish in colour when it is cloudy at night or when it is raining at night?
Rainbows: What causes rainbows after it stops raining?
Rainbows: How high do you have to be to see a whole-circle rainbow?
Rainbows:  Why is the second rainbow backwards?
Rainbows:  
I saw a lovely rainbow recently. The sky just inside the bow seemed brighter than the sky outside the bow. Why?
Rainbows:  Can I touch a rainbow?

Red sunsets: why are mountains pink and the sky red when the Sun sets?
Shadows: what causes the slight blurring of shadows on a clear day?
Snowy green flash:  Last night (12/29/03) we got a freak snowstorm of five to six inches in about two hours, which is unusual for this part of Oregon. It was still snowing hard at about 1 o’clock in the morning when I saw the entire western sky flash several times a bright green color and then maybe an orange color, too. What happened?
Sundog: what is a sundog and what makes it happen?
Sun pillar: A solid, vertical column of light ascended from the just rising sun this morning. What is it?
Thunder: I see lightning but often hear no thunder. Why is there no thunder?
Winter solstice: Why is the Sun is lowest in the sky on the winter solstice and why is the Full Moon highest then?
