Bluue ARC

If you look on Simbad and then look at the Aladin Lite view at full screen there is a longish blue arc at 9 - 10 o'clock. Wo0uld somebody be kind enough to explain it for me as I have never seen anything like this before.

Hi Chinabob
The fact that it is visible only in the blue filter and that it is very straight makes me think it is an artifact.
Looks cool though ! 😄
