Visual Observations:Another beautiful day without much scenery. A few showers on appear on horizon, but otherwise we see only ubiquitous, small cumuli and occasional whitecaps.

Notable Events and Anecdotes:The Cessna made its last fly-bys today for our "large traingle" configuration. Just after sunset we plan to say good-bye to our friendly buoy and dolphins, and steam to RHB's "small triangle" position 20 km SW of Nauru. There has been a flurry of activity in association with tomorrow's RHIB run to Nauru, to occur just after we reach the small triangle position (ETA 0930 local time, 1 July).

Instrument Status:All is well. It was another good radiometer and photometer day.
