aurora borealis?

Highly unusual but not impossible - it depends upon the strength of the magnetic storm that produces the aurora.

Having said that, the only recent one that I can find recorded is that on December 16th 2006 when the aurora was seen as far south as Arizona, but this is still way further north than you are.

I would be almost certain that what you saw was not an aurora but would have to be some other form of atmospheric phenomenon caused by (perhaps) volcanic activity, excess dust in the air. Difficult to pin down without a date.

well im not sure what did u see at philipines because u cant see aurora borealis from near the equatorial, while u only can see aurora borealis on nothern hemisphere...........

also called the Nothern lights, it is seen as green ghostly clouds never have they been red.

Its not one of your volcanos waking up is it?
