Aura... Moon...?

Question

1) was aura seen in singapore?

2) is aura considered a source of light?

3) is moon considered a source of light? even if it gives out the light reflected by the sun and stars?

Answer 1

1,Also known as the northern lights; the luminous, radiant emission from the upper atmosphere over middle and high latitudes, and centred around the earth's magnetic poles. These silent fireworks are often seen on clear winter nights in a variety of shapes and colors.And with Singapore being nowhere near the souh or north pole (it is near the equator) i think it is a lie what you have heard if there had been some sighting im sure there would be a logical explanation or it!

2,The aurora boreialis is considered a source of light as  

The origin of the aurora begins on the surface of the sun when solar activity ejects a cloud of gas. Scientists call this a coronal mass ejection (CME). If one of these reaches earth, taking about 2 to 3 days, it collides with the Earth’s magnetic field. This field is invisible, and if you could see its shape, it would make Earth look like a comet with a long magnetic ‘tail’ stretching a million miles behind Earth in the opposite direction of the sun.

When a coronal mass ejection collides with the magnetic field, it causes complex changes to happen to the magnetic tail region. These changes generate currents of charged particles, which then flow along lines of magnetic force into the Polar Regions. These particles are boosted in energy in Earth’s upper atmosphere, and when they collide with oxygen and nitrogen atoms, they produce dazzling auroral light.

3,The moon is considered a source of light in a way as it isilluminated from light from the sun refracted of the moon surface lighting up our earth with its beautiful looks!

i hope this has helped you

Answer 2

the aura is caused by sun flares, other then that i don't really get your question, i don't think the moon is a direct source of light.

Answer 3

That all depends on the context.

From a universal persoective, no.

But is you are looking at an optics problem/experiment where the moon/aura is the only light acting on the subject, then it can be considered the "source".

Light source can be defined as "something that generates light" in general, or "where the light is comming from" for optics problems/experiments.

As for whether or not aura was seen in Singapore...well I can almost certaily say it has been seen there, at night. The upper atmosphere can get quite cold anywhere. The problem is at night there is not really enough light to notice it, but it surely must have been seen...just not noticed.

I doubt it would ever have happened there during the day, not in the tropics.

But hey, if folks wanna say it has happened, let em go, it doesn't hurt me. And if they ask if I believe in alien space ships, resurrection, alpine events in the tropics or bigfoot I tell em "They could well exist, but I don't believe they do, and I'm fine with you believing them, but don't try force me to."

And if they put a gun to my head I say "well I do believe in them".

And as soon as they go away I call the metal hospital/cops and get the crazy buggers locked up.
