Commentary:
The Cessna made its last flyby today for our "large triangle" configuration.
Just after sunset we plan to say good-bye to our friendly buoy and dolphins,
and steam to the Ron Brown's "small triangle" position 20 km southwest
of Nauru.
There has been a flurry of activity in association with tomorrow's RHIB
(small boat) run to Nauru, which will occur just after we reach the small
triangle position (ETA 0930 local time, July 1).
