Mystery Lunar ray in Mare Serenitatis?

I was experimenting with the curves in Photoshop on this photo (taken last night) to see what I could make out of the Earthshine when I noticed what looks like a ray in Mare Serenitatis that I had not seen before. The ray from Menelaus(?) can just be seen in the square from centre bottom to the top but there is what looks like a ray which is even clearer than this crossing it from the right. Is there a crater in this area which has a ray that can only be seen under certain conditions? (It looks to be coming from Dawes or Vitruvius). I checked all the photos I could find on the web of this area but none of them show a ray.

It’s a mystery to me but perhaps someone out there can explain it. I dont know if Earthshine shows certain features more prominently or whether its the severe curves adjustment in Photoshop, the uncurved original shows virtually no Earthshine. Unfortunately it was the only photo I took at this exposure (Nikon 4500: 1sec, 100iso) so I have nothing to compare it to. Any Ideas?

Stefan,

Very interesting. Maybe when Serenitatis comes into the light we will see a new crater named after you!

Looks like an internal reflection of the crescent to me...at those extreme brightness levels, there are bound to be reflections like this.
