Anyone know what this weird brown spot is?

Hey all. So I went to collect my girls’ eggs today and saw this one in the nesting box. Not 100% sure who laid it. The rest of the egg is normal and it’s normal on the inside. The shell is a little bit thin but nothing extraordinary. There’s just this weird brown spot on the very top of the egg. I’m assuming that it’s nothing but I just wanted to hop on here to double check!

It's fine, just a glitch in the bloom coating.
The lighter part is excessive bloom.
