Looked at information from 87% of the southern hemisphere sky and still nothing that could be Planet 9. More info (but not much) at

https://www.livescience.com/planet-nine-still-no-evidence

Thanks!

Similar report from here:

Still searching for Planet 9

The solar system has eight planets. In 2006, astronomers reclassified Pluto as a dwarf planet, the same class that contains Eris, Sedna, Quaoar, Ceres and perhaps many more solar system small bodies.


Many thanks,
