Please share your thoughts on the above observations.

Need confirmation on two aspects: 1. Luminous intensity of a fire should be in the range of 500 candela to be visible from a few miles across in the night 2. Can a man-made fire on a plate of camphor produce 500 candela of luminous intensity

Can someone share their thoughts on this? TIA

Please share any additional thoughts on this... Thanks

Can someone share their thoughts on this?

Based on technical details of beacon lights, 300-500cd light is required to be visible from a couple of miles. Link: http://en.wikipedia.org/wiki/Aircraft_warning_lights !The common medium white strobe flashes 40 times in a minute, !at an intensity of 20,000 candelas for daytime/twilight...

Thanks so much for the time and information. Really appreciate the help on this.

Thanks for the details. Is there any way to prove (theoretically) that the light source should be at least 300-500cd to be visible from a couple of miles?

Please help. Thanks

Been reading a lot on this. From what I have read, it seems the light source should be at least 300-500 cd do to be visible from a few miles. Considering a 100 W incandescent light bulb emits about 120 cd, we need at least 250W - 420W? Is this possible from a fire to match this? If so, using...

Thanks for the excellent details. Here is a pictorial depiction - * is the place of fire, **viewing point and ~ is just a filler to help with white space mgmt. Both are hill location at least a few thousand feet above the ground and separated by at least a couple of miles. /\ / \*...

Thanks for the details. There are no concrete measurements for this phenomenon. The main objective being it (the fire) should be visible to "naked human eyes" at night from a few miles? Can this be achieved? Will a plate of camphor do the trick or will you go for a more conservative 1mx1m fire?

Attributes shown by the fire: 1. It happens quickly and is controlled - does not result in forest fire or visible smokes 2. The fire blinks (appears/disappears) three times or gives the illusion 3. Remember the fire is watched from a distance of a few miles Key questions: 1. Can a...

It should be a controlled fire rather than blowing something up.

Can a fire say in a dish plate with a pile camphor be visible from a couple of miles in the night? What would it take to put a fire visible from a few miles? Will a pile of camphor in 1mx1m do the trick? Been puzzled with this question for a while and thought the experts in this forum can help...
