Can you tell me where is exactly Harry Pottter's Scar?

The famous scar of Harry Potter is very popular now. it is taking the shape of lightning bolt at his forehead.
He got it as the result of failed attempt of murder by Lord Voldemort.
Potter was only 15 months old at that time.
He and his family was attacked by the killing curse by Voldemort, the Prince of darkness.

Harry Potter was the only one who could survive from the attack as his mother protected him with her loving sacrifice.
It left Potter with the scar on the forehead and made him famous as "magic boy" in witchraft world.

But do you know where it is? on the center of forehead? on left side or right side? As you can see that in the trailer of "Harry Potter and the Sorcerer's Stone", the scar is located at the right
side and end up above Harry's eye.
well, mostly we assume that the scar is located at the centre of the forehead, as the cover book showed. But Rowling (www.ew.com) revealed that she never point out in her writing where is the exact location is. As for the books, the illustrator said the placement of the scar was left up to her. So, everybody should has their own interpretation on this (www.ew.com).
