What's the blue bit? (Accidentally posted in help)

by jedkat

I can't find any indication of it on sky server, but it doesn't look like an artifact: http://skyserver.sdss3.org/dr8/en/tools/chart/navi.asp?ra=190.89778572&dec=-0.23507165

any help would be great!

The fact that it is just visible in one filter makes me think artifact ! These UKIDDS images have their artifacts too ! -D

The blue thingy could be a foreground star. This is an infrared image and the artifacts are very special ! 😄

There's not star when you look at the image in SkyServer. In fact, there is absolutely nothing where the blue blob should be.

Then it is an artifact. With these infrared images we get lots of new artifacts!

Could the blue object be another Voorwerp?
