Thanks for all your answers :) I can't believe that it's only a visual effect, it seemed so near.
I haven't seen it again from that time, but i'll have a look around the 14th day of lunar calendar (thanks Ertw) . It's the 26th of Dhul Hijja, i'll have to wait around 15days to see it again.

Yes that enlarged moon you can usually see around the 14th day of the lunar month every month. I've always enjoyed seeing that. Yes it is an optical illusion!

It was probably a full moon seen at a low point out in the horizon. Maybe the atmosphere had some clear clouds that reflected the blueness into your eyes.

Hello Layla

yes I have seen moons like that, in blue, red and brown, huge like a planet in a sci-fi painting, like a dream ...
but it is not really a bigger moon, it is just a visual trick that our eyes and minds play on us. that phenomenon was discussed and studied a lot. The truth is, the distance of the moon from earth is static and there are no wather effects that causes us to see it that way, it is just our eyes that play a trick on us when the moon is low near the horizons and we see it much larger in comparison to objects near by like trees and buildings. so never mind the why and just enjoy one of the gods most beautiful shows.
