I'm surprised at the Chinese Lantern theory still going around -
After some research, the only lanterns I could find were about 42 inches in diameter - that's rough 3.5 feet. Pretty small object to see at 3+ miles.
Anyway -
After some seriously complicated math (fyi I am not amazing at) of which I will not go into detail of unless requested it appears that it is unlikely
to see an incandescent light bulb (which is approximately how much energy a Chinese lantern would give off) in a 1 mile spherical radius (my math
points to about .56 w/m2 @ 1 mile, which converted to lumens/per square foot is about .0088 which would pretty low light).
If we look at where the viewers were (Highlands in Hollywood) and where the park is where they would probably let Chinese Lanterns go the distance is
roughly about 3 miles. My math shows that a typical lantern at 3 miles would be giving off .0009 lumens per/sqft - to be able to see an object
illuminating just .0009 lumens per square foot in 3 mile radius is pretty damn amazing. From what I understand, using the Inverse Square Law, as the
distance of a spherical radius increases, the intensity of light decreases as the distance is doubled. As it were, we know our viewers were 3 miles
away from a possible point of Lantern deployment - so at that distance, a Lantern would be giving off very very little light. This is not taking into
account atmospheric conditions.
What they witnessed was giving off pretty bright light. You have to keep in mind that a lot of Lanterns today come with light bulbs for safety reasons
- but even if it were flame based it would still be showing in the same wavelength as incandescent bulbs and as such same spectrum - so the numbers
should be pretty much the same.
Now, like I said, my math could be off - this is complicated stuff and I'm not a math guru by any means. I just wanted to get some numbers to see if
we could really spot a typical Chinese lantern in the given 3 mile radius.
If my math is correct, I don't think we're looking at Chinese Lanterns here.
