Just to bring this thread up to date...
It looks like the Port Pirie end of the event is a non-starter. RIP
We now have an observing team that will observe north of Broken Hill, made up from 2 local observers and 6 blow-in observers, driving and flying in to BH from Sydney and Canberra. Most of the blow-ins will operate two or more stations, simultaneously or at the same time.
Apart from obtaining good contours of the lunar limb, we hope to obtain measurements for the diameter of Antares and possibly observe limb darkening effects. The Antares disk will have a diameter of about 85m at the lunar limb (0.0438") so we hope to observe disappearance and reappearance events lasting perhaps 1 second or more.
Watch this space for the results of our endeavours.
