It is a female Gonia, it looks a bit weird in colouration. Is the reflection by a flash or simply the sun ?

It is simply the sun, I didn't use a flashlight.

It almost looks like vacua. How eastern are you ? East of Hannover ?

The coordinates are 53.318703, 10.712973.
It is about 50 km east of Hannover, and about 100 km north (about 50 km southeast of Hamburg).

Yeap, it is vacua ! Should be very rare in western Germany, but recorded for Nordrhein Westphalen. I know by own experience it is relatively common in northeastern Poland.
I am not sure if it is mentioned for Niedersachsen in the new checklist by Stuke.

Fine, thank you very much!
Gonia vacua is indeed not in Jens-Hermann Stuke's list for Niedersachsen and Bremen.
