Hi !
I dont know where it was at mid-day but at 16h30 he was flying over the Normandy beatches!
Here extracted from one of his photos that you can find in the book: Normandie 44 - Les photos de l'avion espion - Philippe Bauduin & Eric Charon - ISBN: 2-91-2047-02-1
From others photos Erich Sommer also flew on 4th August 19h30 and Oblt Götz on 12th August 15h45, but Mr Bauduin explained that they found only around 20 from the 380+ photos, and that around 12 missions had been flow between 2nd and 12th of August by the Ar 234.
It is also said that 12 technicians were at Juvincourt instead of the usual 2 so we can imagine that interpretation was far quicker than usual.
