Green thing on the left

    Hey so I just noticed this green thing on the left when I was about to classify it.
    Any idea what it could be?

    Hi Yenthelufin and welcome to the Zoo

    The green line on the left is an optical artifact. It's a cosmic ray hit that didn't get removed. You see these colored lines quite frequently in these DECaLS images.

    Also it is not necessary to post your questions twice.

    Happy hunting ! 😄
