Commentary:
We saw our last land for 8 days about noon today en route to the tropical
atmospheric ocean buoy nominally at 2 S, 165 E, but actually at 1 - 55.8
S, 164 - 23.4 E. Many flying fish were seen today, prompting the ship
to cast out trolling lines. Last night's attempts at high-frequency radio
communications were marginally successful with Mirai, unsuccessful with
Nauru. We may try different times and/or frequencies tonight. Everyone's
spirits seem to be soaring as we approach the first mission milestone
with sensors in good shape, stomachs settled, and glorious weather.

Visual Observations:
Glassy seas, no wind. Beautiful weather with small marine boundary layer
cumuli and higher patchy cirrus.
Instrument Status:
The C-band radar is operating again after repairing the coupling between
pedastal drive motors and az-el gear boxes. We set up a VHF aircraft radio,
high wattage base unit, on the bridge in preparation for Cessna flights
tomorrow when we arrive at the buoy, ETA 0500 Z (1700 local time).
