... Following the full moon on Monday, March 24, I was able to make use of a few brief periods totalling about an hour and a half before the Easter weekend to make some 160 galaxy observations at home in Coonabarabran using the 0.41m telescope. ... Because of being on holidays my resources for comparison purpouses were rather limited, and so I had to rely upon amateur contacts in Queensland to verify my memory of this galaxy, and also to obtain visual confirmation of the supernova. ...

... We have measured this "redshift" for the pink black holes, and allowed for it in our calculations. ... We see this effect in the emission from gas around these pink black holes, but it is far too small an effect to account for the pinkness. Thus the swirling motions of gas around or into the black holes cannot produc the colour. ... At first we thought that these things were normal blue black holes hidden behind clouds of interstellar dust, that absorbed the blue light and made them appear pink. ...
