HCG-51 Update

I got into contact with the British Astronomical Society about the mysterious "star" on HCG-51b ... had I just discovered a supernova or something exciting like that? Well, no. But that isn't too surprising really!

It turns out that the Aladin search plates that I (and others) were using did not go deep enough for finding stars this faint. To go this faint you need to use the SDSS SkyServer - something I was not aware of until now, but will certainly use again. A search on this returns a positive identification of a <20 magnitude star superimposed on the galaxy.

Better luck next time eh :)
