Here's an excerpt to help determine height of a flare sighting:
* Closed Fist Method (determining distance from reporting source): A closed fist held at arm’s length with the thumb side up represents approximately 8 degrees of arc. When the bottom of the fist is aligned on the horizon relatively accurate estimates of small vertical angles can be made. If you hold your fist at arm’s length, with your thumb on top and the bottom of your fist on the horizon, was the top of the trajectory above or below the top of your fist? If the flare was sighted below the top of the fist, have the reporting source attempt to more accurately estimate the angle with the horizon.
Caution: I have two brain cells. Sometimes they both work at the same time.
