Simone, I'm afraid that I'm not going to be able to give you a very good answer without more information. The explanations for this could vary depending on where in the sky your mother saw this light, how far away it was when it started, how far away it was when it disappeared, the shape of the light, the size of the light, etc. But, I'm not going to let a lack of information stop me from making some wild guesses. You asked for a rational hypothesis, so here are a few. 1). Your mother actually saw something, but it was only a trick of light. It could have been several things. It's possible that it was a reflection from something in the sky, like a helicopter, or the reflection from someone nearby opening a window, or a reflection from any number of things. 2). Your mother actually saw something, and it really existed. So, I suppose it could have been a UFO, but without more evidence, I kind of doubt that. I did find some information on the internet about strange, floating balls of light that can move rapidly around the sky. I can't verify how true the phenomena of "Earth Light" is, but if you want to look at the web page (and even see 'real pictures' of "Earth Light," check out this link: Triangle Study Web Site 3). Your mother thought she saw something that wasn't really there. There are any number of ways this could happen. The brain, after all, is a pretty complex thing. The human eye is a pretty complicated bit of biology, too. One thing that comes to mind is the possibility that your mother has migraine headaches. Certain people who suffer from migraines experience an 'aura' about 20 minutes before the headache in which they can actually see bright lights, among other things. If your mother didn't get a headache right after seeing this light, then it is possible that she is a person who gets the migraine aura but never actually gets the headaches. That condition, although not common, can occur. To learn more about migraines and auras, look at: Journal of the American Medical Association Migraine Information Center Well, I doubt we'll ever explain exactly what your mother saw. Hopefully that was the first and the last of that light she'll ever see...
