   Heading: 047 deg
Surface Wind: 10 m/s @ 127 deg. (14 m height)
Air Temp: 27.3C (13 m height)
Sea Temp: 27.7C (5 m depth)
Rel. Humidity: 69.8% (13 m height)
Precipitation last 24 hr: 0 mm

Radiosonde Inversion Height: (no sonde)
Visual Observations:
Broken overcast with patches of blue sky. Winds are still strong enough to generate whitecaps.

Notable Events and Anecdotes: Today RHB moved from the Coral Sea to the Solomon Sea via the Jomard Passage. With sheltered waters and a trailing wind, the ride became noticeably smoother. Tropical lagoons, long beaches and palm trees tempted a few scientists to consider jumping ship! Yesterday better HF radio communications were established with Mirai and Nauru: RHB heard Mirai, Nauru heard RHB and passed messages to Mirai. We saw several ships today, including a huge tanker, a sport fishing vessel, and a wreck (on a reef).

Instrument Status: C-band radar locked up in vertical direction and was turned off. We await diagnostics and advice from U.S. before attempting to reconfigurae and restart. We discovered that our helium supply (for radiosonde balloons) is lower than thought because only 18 cylinders were filled in Darwin, not 24 as expected. This may cause rationing of radiosonde flights.
