Hi Peter,

Predictions of Pluto events depend on the ephemeris and star catalogue used. The Gofin prediction you refer to doesn't specify the ephemeris used.

The prediction below was used using DE432 and UCAC4 and the path covers almost all of Australia and misses New Zealand.

Felipe Braga-Ribas of The RIO group use the older DE430 ephemeris and "special sauce" to apply offsets for Pluto. They also spend a large amount of observing time to obtain good position data for the star. The RIO Group has an excellent record for producing quality predictions and we hope that they publish updates as the date of the event approaches. We will also publish the updates here.

You can also expend lots of energy worrying where the path might lie, or you can observe regardless of any prediction. Observe first, worry second would be my tip.
