That's a bright star causing an image artefact just off the end of this image.

Which one is the arc? The two possibilities I see the arc is too far away.

There are no lenses in this image 😃 It is one of the training images that *do not * contain any lenses 😃

Pink & purple galaxy combo to right of top center blue, in upper right. Lower purple zoomed is an arc, orange minor arc, lens between them.

No, it is a diffraction spike coming from a star just off screen to the left.

We put this one into the refinement training set, and it's fooled a lot of people! The red galaxies are all too lightweight to be lenses.

When a red galaxy is as small and faint as these are, any lensed features should lie very close to it indeed - unlike what you see here.
