highdesert50 Posted December 6, 2016 #2 Share Posted December 6, 2016 First impression is that of the Hessdalen lights of Norway. Perhaps Australia also has a naturally occurring battery. Link to comment Share on other sites More sharing options...
kartikg Posted December 6, 2016 #3 Share Posted December 6, 2016 A decent telescope can help to solve the mystery. Someone who is near the location can arrange it by contacting local astronomy club. Link to comment Share on other sites More sharing options...
AcousticAsylum Posted December 6, 2016 #4 Share Posted December 6, 2016 Sounds similar to the Paulding Light, we have up here in Michigan. Cool story nonetheless, hope it remains a mystery. Link to comment Share on other sites More sharing options...
stereologist Posted December 6, 2016 #5 Share Posted December 6, 2016 I like the idea that there could be an atmospheric effect involved. I am surprised that people thought they could tell the distance to the light across a dark expanse. 1 Link to comment Share on other sites More sharing options...

If you have time/chance, try with the moon, that's bright a relatively big, and see which are the results. As stereologist can explain you way better than me, they are not so good.

Habitat Posted December 7, 2016 #12 Share Posted December 7, 2016 I have been in that area, I was on a dirt road late at night and saw what I thought was the lights of a car approaching in the distance, but it never arrived, and there were no roads branching off. I am not claiming it as a Min-Min ! I spoke to an old guy who had spent most of his life in the area, who claimed to have seen it many times, from what I recall of the conversation, he said the light was quite dull, something like a kerosene lantern luminosity, and he tended to the theory it was a bird of some kind.

This was a long time ago, mid 1970's, Boulia area, the fella I spoke to was around 70 I'd say, possibly late 60's. He did not make a big deal of the Min-Min light, very matter of fact, but I do recall him insisting the light was not bright, and resembled that of a hurricane lamp in intensity. and he said he had seen it many times. Could be some kind of bioluminescence. Anyone who has been at sea at night, is likely to have seen wonders of bioluminescence that are hard to believe are not artificial light. 1 Link to comment Share on other sites More sharing options...

That of course is bioluminescent plankton "lighting up" when disturbed by the dolphin's passage through the water, it causes me to wonder whether hydrodynamicists could use this phenomenon to better study water flow around objects like boat's hulls, etc. 1 Link to comment Share on other sites More sharing options...
Calibeliever Posted December 7, 2016 #19 Share Posted December 7, 2016 They tried with dolphins a while back but it proved to be tough to capture the right circumstances: http://www.americanscientist.org/issues/pub/shedding-light-on-dolphins The relevant bit: " By recording the ghostly, blue-green bioluminescent halo around the moving dolphins, Latz and Rohr were able to examine the flow of water over the creatures as they coasted beneath the camera. The study revealed that the hydrodynamic boundary layer is typically quite thin up front and that, contrary to expectations based on simple fluid mechanics, the flow does not separate from the body of the animal along its flank.

If you have time/chance, try with the moon, that's bright a relatively big, and see which are the results. As stereologist can explain you way better than me, they are not so good. It's true that phones in cameras are generally not all that good in dim light - they are getting better, but you need to spend a lot to get a half decent one.. There is no substitute for a large sensor and a large lens, so that it has a chance to gather lots of photons. Moon images are a different problem.. Even though it's quite a bit bigger than a star (or Min Min light), it's still quite small in terms of how much of the scene it occupies, and as the rest of the scene is probably very dark, the camera adjust for that, resulting in the Moon being complete overexposed - it blooms out to a white featureless blob. The correct exposure for the Moon is more like a normal daylight exposure - some cameras allow you to override the exposure so you could do better.. If you are stuck with a camera phone and want to record a dim scene, then you should try: 1. Keep the camera as still as possible - a car roof, a fence post, power pole.. jam the camera hard against it.. 2. Try to include background - while you are probably tempted to zoom in, this may not be the best thing to do...when the camera is zoomed in, it collects even less of those photons. And see 3. 3. Don't use 'digital' zoom - check the manual and turn it off, or if it always does digital zoom (ie it does not have real optical zoom) then don't zoom at all. Digital zoom is effectively worse than useless as it creates false detail - that might be ok on someone's face, but it's NOT ok for analysis. 4. Experiment in advance - try out the different modes and settings your camera may offer - some may work better at night than others (and it won't necessarily be the 'Night' mode that is best! And if your camera has trouble autofocusing at night and keeps racking back and forth making the stars/streetlights big then small, over and over... well, you may as well not use that camera for this purpose unless in one of the modes (eg Landscape) it sets focus to infinity (not many do, sadly).. Read your manual.... If in doubt about a particular camera's capabilities, or what to buy if you want something a bit more serious, just ask.. 1 Link to comment Share on other sites More sharing options...
