gigantic LSB galaxy

• by planetaryscience

  Sorry if this is a bit rushed, I have some work to get to at the moment, but looking for a target star for an upcoming asteroid occultation, I was looking around the surrounding field in PANSTARRS, and found this:
  
  

  The galaxy appears to just be a tiny nebulous cloud in every other survey, and in the G-band (pictured above) is where it is visible most (which is barely at all). It is not an artifact, as it is also just barely visible in the R band as well. Assuming it's at a similar distance to the other galaxies in the region, it could be over 150,000 light years across! Is it a very inactive star forming galaxy, or possibly a LSB galaxy?

  coordinates for reference:
  
  RA: 12 26 41.31

  SDSS dr12 - out of footprint
  DECaLS - out of footprint? can't get it

  Examples of PanSTARRS artifacts - doesn't look quite the same

  It seems that somehow PANSTARRS G and R are the only bands to have ever seen this object. GALEX doesn't cover deep enough, and no other survey is in the right band to see it.
