Can someone tell me what this is... I know it's nothing 'special', I just want to know what's going on.

  Why is it squashed in the WISE1 frame?

  Hi Akim

  Sometimes the star is blended with other objects.

  That would be my guess too.

  This is what is going on:

  There is an issue in the AllWISE data concerning saturation and dropouts at WISE 1 -2, i've seen a lot of dropout flagging since this post, but when you spot one you should check for the AllSky data for the IR excess, here:

  #dropout #AllSky excess 0.034

  sometimes you have a dropout AND a genuine IR excess.

  sometimes you have a W2 dropout too:
