Forum:Basic doubt about book of moon...

Well, I have a very basic doubt....My doubt appeared on a situcion like this:

It's player A turn.

Player A has a face up monster ...

Player B activates Book of Moon targeting this monster during player A Main Phase 1....then the monster is flipped face down in defence posicion....

My question is: Can player A flip his monster to face up attack posicion at this same turn???
