Answer 1

sounds like heat lighting.

Answer 2

A single bolt of lightning can travel as fast as 60,000 miles per second.

Average lightning stroke is 6 miles long.  Average thunderstorm is 6-10 miles wide.  Average thunderstorm travels at a rate of 25 miles per hour. Once the leading edge of a thunderstorm approaches to within 10 miles, you are at immediate risk due to the possibility of lightning strikes coming from the overhanging clouds.  Because of this  lightning can appear to occur with clear skies directly overhead.

Answer 3

You may be seeing lightening but it's too far away to hear the thunder. When you see lightening you count until you hear the thunder and that's how far away it is, so for example if you count to 5 before you hear it, it is 5 miles away. So you can see how it could get so far away you would never hear it.

Answer 4

I would say it is heat lightning.
