  Foreground star or #supernova?

  looks distinctly like a supernova to me, in terms of colour, brightness and location within the disk of the galaxy.

  Yes, possible #transient. There is no sign of the object in Pan-STARRS, but the dot may be too faint to show up there.

  Visible in multiple bands in SDSS DR7 and PanSTARRS1, also has a spectrum in SDSS so likely starburst area in the galaxy https://tinyurl.com/y7pzxyj9

  I chose image size:1000 pixels and JPEG display size:1024 pixels in Pan-STARRS1, but with those settings the dot can't be seen. Strange!

  One would have thought the more pixels the better 😉

  Visible in PanSTARRS using 240 pixels and 256 size. Too blue to be a supernova, should be green, and as GS said, a starforming spectrum.

  as always; less = more 😉 But the trick is that PanSTARRS doesn't visualize the data the same way as SDSS (which equals jpg's) does, but uses an algorithm to adjust the brightness depending on brightness of all visible sources. That's why a bright foreground star 'dims' all the other objects in the image. You can either zoom in until those aren't in the frame anymore, or adjust the 'autoscale' value in the URL 😃

  made me appreciate PanSTARRS images more, just zoom in far enough on the nucleus of a '''too bright' galaxy and you'll slowly start to see more details then possoble with other surveys

  In the future I'd better not use too many pixels when looking for transients in P. I have to abbreviate. I only have 140 characters 😄

  Ah yes I remember those restrictions. That was before I could see the Matrix. 😉
