Tonight the Moon and Jupiter will be quite close. The pair will rise at nearly the same time, about 17:08HST. The Moon will be very near full, 98% illuminated and about 5° from the bright planet.
A Flooded Camera
When diving with a camera you understand the situation… It is not a question of if you flood the camera, it is a question of when you flood the camera.
Just 15-20ft down on a dive off the old Kona airport, I went to turn the camera on and saw something that made my heart miss a beat. The camera case was half full of water. Nooooo!
As we were just starting the dive I popped to the surface and drained the case. I knew that the damage was already done, salt water and electro-optics simply do not mix. Re-seating the rear hatch I dive again, the leak has stopped.
Continuing the dive without a camera was painful. I dive to shoot, not being able to take photos takes the color out of the dive. At least nothing special wandered by, no 14ft tiger shark or underwater humpback sighting, that would have been excruciating.
The leak appeared to be on the rear hatch, I could see a trickle originating on the top right corner. Some small debris in the seal? A slight kink in seating the seal. Later examination shows nothing wrong, I will probably never know.
The memory card appears to be just fine, I read out the few shots that were on it. This includes the photo of the folks drying coffee on the old runway. I simply marked the card so I know which one it was in case there are questions about the reliability later. The camera battery also appears to have survived the immersion, need to use it a through a couple cycles to be sure.
Otherwise the camera is an expensive desk ornament.
As Pete said after the dive… “Insert $400 to play again.”
Fortunately there is EBay… Inserting a mere $200 has a used G12 on it’s way for me to play again. It appears the the G12 is old enough that used cameras are very available and the prices are falling. I may want to pick up another one. This is why I use a few hundred dollar camera underwater, not a few thousand dollar camera, it will happen again. In the meantime Pete is currently assembling a Canon 5D MkII underwater rig. Not me.

Postcard from Hawai’i – Drying Coffee
Rigging scuba gear at the old airport park, a nice place for a Saturday morning dive with the guys. Just in front of my vehicle a couple is spreading large tarps on the pavement. Setting up a party pavilion? Then the bags of beans get unloaded… They are drying coffee! The old runway with hot asphalt in the sunlight is a good place, those beans will dry fast!
Only in Hawai’i…
Hubble and Keck Unveil a Deep Sea of Small and Faint Early Galaxies
W. M. Keck Observatory press release…
A team of scientists led by astronomers at the University of California, Riverside has used NASA’s Hubble Space Telescope and the W. M. Keck Observatory to uncover the long-suspected underlying population of galaxies that produced the bulk of new stars during the universe’s early years.
Study results appear in the Jan. 10 issue of The Astrophysical Journal, and will be presented today (Jan. 7) at the 223rd meeting of the American Astronomical Society in Washington DC.
The 58 young, diminutive galaxies spied by Hubble were photographed as they appeared more than 10 billion years ago, during the heyday of star birth.

Venus at Inferior Conjunction
Today, at 02:25HST, the planet Venus will pass through inferior conjunction, passing between the Earth and the Sun. Venus will remain hidden from view for another week, emerging in the dawn sky around the 18th. Maximum elongation will be on March 22nd at 46.6°W.
Unlike 2012 there will be no transit, from our point of view the planet will pass over 5° north of the Sun. The next transit will not occur until 2117.
First Detailed Look at a Normal Galaxy in the Very Early Universe
W. M. Keck Observatory press release…
University of Hawaii at Manoa astronomer Regina Jorgenson has obtained the first image that shows the structure of a normal galaxy in the early universe as captured by the W. M. Keck Observatory. The results were presented at the winter American Astronomical Society meeting being held this week near Washington, DC.
These galaxies are known to contain most of the neutral gas that is the fuel for star formation, so they are an important tool for understanding star and galaxy formation and evolution. Discovered and classified over 30 years ago, they have been notoriously difficult to see directly.
Dr. Jorgenson, an NSF Astronomy and Astrophysics Postdoctoral Fellow at the University of Hawaii’s Institute for Astronomy, worked with Dr. Arthur Wolfe of the University of California, San Diego. They used the advanced technologies of the W. M. Keck Observatory on Mauna Kea to obtain the first-ever spatially resolved images of a galaxy of this type.
The galaxy was detected with the 10-meter, Keck I telescope fitted with OSIRIS and the Laser Guide Star Adaptive Optics system.

Kepler Team Validates 41 New Exoplanets with Keck
W. M. Keck Observatory press release…
The Kepler team today reports on four years of observations from the W. M. Keck Observatory targeting Kepler’s exoplanet systems, announcing results this week at the American Astronomical Society meeting in Washington. These observations, from Keck Observatory on the summit of Mauna Kea, confirm that numerous Kepler discoveries are indeed planets and yield mass measurements of these enigmatic worlds that vary between Earth and Neptune in size.
Using one of the two world’s largest telescopes at Keck Observatory in Hawaii, scientists confirmed 41 of the exoplanets discovered by Kepler and determined the masses of 16. With the mass and diameter in-hand, scientists could immediately determine the density of the planets, characterizing them as rocky or gaseous, or mixtures of the two.
