Is this a nub?

[Emsabub]

Hi everyone!

Could anyone tell me if this is the nub?
There’s a white line in the same place pointing straight out to the left side on two other images but this one the legs got in the way!

Thank you!

Too low for the nub I'm afraid, and a little early for a guess. Would it be possible to get a private scan on the 13 week mark to get some lovely clear nub shots!
