2013 BO76 for the Southern hemisphere

[PMSchu]

I forgot to mention that the peak brightness is estimated to be 15.6 magnitude on Mar 22. It'll be reflecting sunlight, but I don't know what color it is. Perhaps a green filter would improve the contrast. Just guessing though. If you have a contrast enhancing filter, try it out on a bright MP to see if it helps or not. Perhaps one in Libra or Scorpius. 

The bright moon will interfere.
