Binary star?

The yellow feature at the right may be a binary star. Does anyone see it in the SDSS Skyserver image?
Or is it a glitch?Posted

Good one, has me stumped tbh.
Can only see it in VSTKIDS r band, no other surveys, no supernova entries, not in catalogs. But definitely not artifact-squarish shaped, more a bright pill-shaped extended source.
Strange that it's not in any other VSTKIDS band, but not impossible for a supernova (if r band was imaged last). Hmm should check the different obs dates / images from the different VSTKIDS Data Releases. Got no time now + VSTKIDS FITS files are over 1GB a piece....
Or perhaps the minor planet center, OR it's a CCD fault artifact but I couldn't tell because haven't seen one before i think...
Here the VSTKIDS gri image mapped to GRB equal to SDSS images:

Saw it was imaged by UKIDSS (IR) too so checked different bands in Aladin Desktop, but nothing there either.

For me, asteroid. It has a pure amber colour and may be 5 images smeared together.

Ah, like the two examples posted here only brighter and more compressed?;

Yes, that seems a likely explanation. The slower the object in our solar system is moving, the more compact it would be. Amber colour. The biggest stars haven't changed in any of the images. Supernova would be blue in colour and it is just too big?
