Hello all. I live in Singapore, located somewhere at the equator. Just a few nights ago i spotted something rather strange. I looked up into the sky and to my astonishment, there was this region of clouds that was illuminated orange in colour every once in a while. It's like glowing at a regular rate. All over the sky i could only spot that particular region of the sky glowing on and off... Can't be the effect due to atoms in the sky being ionised, like in the case of how auroras are formed, right? I mean, as i have read, auroras can only be formed near the tip of the globe where the magnetic fields are at their strongest. Can somebody please enlightment me, this ignorant individual in the field of astronomy/astrophysics, on what i actually witnessed and if possible give a rather simeply explanation along with it? Your kindness i thank you.
