I think it only happens in areas near the poles. I have not seen one and probably a lot of people have not seen unless they travel to those countries that have it.
you can see it at both poles but its more difficult at the South Pole because there is no easily accessible land to observe from whereas in the North, if you travel up Norway to where Santa Claus; official home is, you will be able to catch it...

Only super intense radiation will cause such aurora to appear at the equator. Because these particles are charged so that they get attracted to the poles, you will need a very intense storm that the Earth's magnetic field cannot cope with, to see such a nice thing here. By which time, i guess we'll probably be dead from the radiation.
Conclusion? I'd rather not see this nice thing in Singapore ^^ However I'd wish to travel up there someday so i can enjoy the nice views of it. Better still, move to Canada so i can enjoy it every night.
