Two telescopes set up on the side of Mauna Kea. Olivier’s 12″ and my 18″ Deep Violet. A full night of deep sky observing under very nice conditions.
The photo was taken with a red LED light swept over the area during the 20 seconds of exposure. The camera had other ideas, set for automatic white balance it attempted to correct the color, fairly successfully. Surprising given the monochromatic nature of the light source.

I have not done much diving south of Kona, usually diving the shores close to home, the reefs of North and South Kohala. I have done a couple dives at Two Step, at Hōnaunau. The terrain is different further south, there are different species to see. Last weekend I got a chance to do some more diving down south.
This was made possible through a friend and fellow Keck engineer. Dennis owns a boat. Not just any boat… The Aqua Safari… A big boat, a fast boat, a dive boat, equipped for scuba, actually a pretty nice boat. I was invited to join the guys for a dive outing. I didn’t even ask where we were going, it really didn’t matter, I just wanted to dive.
Mark Devenot exploring the reef drop-off at TanksWe headed south of Kona to a dive site I had never explored before, a place called Amphitheater. Just around the corner from the famous Kealakekua Bay, the site features some large sea caves carved into the cliffs by the winter waves. An excellent site, featuring good fish, numerous lava tubes, and good coral cover. Visibility was great, allowing good photographic conditions.
A find of the dive was a Bearded Cusk Eel hiding in a crevice at the base of a rock wall. I managed one half-decent photograph before it disappeared further into the crevice, out of sight. I guess it did not like the strobe, cusk eels are notoriously shy.
Mark, Patti and I shared the meal preparations. They had brought sandwich makings, I brought tuna mac, drinks and chips. Deb even sent a long a batch of home-made chocolate chip cookies. We ate well indeed.
The second dive site was Tanks, a site just north of the old Kona Airport and south of Honokohau. A fair amount of surge made mooring quite a challenge, we actually gave up on one mooring buoy, too close to the rocks where we were getting bounced around. There was quite a bit of surge underneath as well, and visibility was poor. At least poor by Kona standards, fairly good for most anywhere else. The surge and vis did not preclude a decent dive, we descended to the edge of the dropoff, where the slope plunges into the deep blue abyss. A few good photos, including a Undulated Moray. We spent the last part of the dive exploring a number of small caves just under the shoreline, where we found several white tip reef sharks, including one of the largest I had ever seen. This shark was a bit more than six feet, and quite rotund. He lived up to the scientific name for the species Triaenodon obesus.
A great day and a couple good dives. That was the goal, and that was what we achieved. Thanks Dennis!
Yes, it is three in the afternoon and I am just waking up. That was the plan.
A night spent under dark Mauna Kea skies with a telescope. It has been much too long since I had a good night out with the ‘scope, it was time. A few items conspired to make it happen… Good weather, a note from the HR department that I was at maximum on accumulated vacation time, use it or lose it! Additionally, my friend and co-worker, Olivier Martin, was looking for a night of observing as well.
With a couple days of approved vacation I headed for the mountain.
A partly cloudy sky greeted us on arrival, high and heavy cirrus hid much of the blue. The forecast was for this to clear off during the first part of the night, not yet time to panic. Not wanting to deal with the crowd at the Mauna Kea VIS we hid out in a spot I found on one of the nearby back roads, a place where we would not be disturbed by any visitors through the night, a place that is completely dark.
Olivier beside his new telescope, a 12" Orion DobsonianOlivier brought his new 12″ Orion Dobsonian. And I do mean new, it was not yet fully assembled! The usual troubles of life had conspired to rob him of any time in the few days since the telescope arrived. He had assembled the main parts, the base and OTA, but had yet to install the elevation bearings, handles, encoders or the primary mirror. Thus we spent the first two hours finishing the telescope, no problem as final assembly gave the heavy cirrus clouds time to clear out.
A plumeria lei left outside Keck ObservatoryA common sight atop Mauna Kea… An offering to the gods or spirits believed to reside on the summit of this incomparable mountain. A lei of flowers or a package wrapped in ti leaves, often placed on one of the ahu that are to be found in the summit region. We leave these offerings alone out of respect for those who continue to worship on Mauna Kea.
Early this week we were surprised to find a set of plumeria lei on one of the pillars in front of our building. Bright white and yellow, the scent of the flowers hanging heavy around the loading dock door. Quite a contrast in a world of dark red cinder and cold, a bit of the tropics that lie far below the summit.
Why would someone leave the lei at our door? A thank-you for what we do? A gentle protest at our presence on the mountain? I wonder as we drive down, lost in thought.
Public awareness of a unique astronomical event, the Transit of Venus, is appearing. While avid sky-watchers have been anticipating this event for years, the general public is mostly unaware of the event.
This seems to be changing… A number of articles have appeared in the mainstream press this last week, from MSNBC to Fox News, providing information about the transit.
Yes, it is the same article on all of the sites, all apparently picked up from the Space.com site. There is some lesson here on the nature of corporate news today. In any case it is nice to see an astronomical event getting coverage. Any opportunity to get more astronomy onto the public stage is to be taken advantage of.
A transit is a less spectacular event, not exactly a total solar eclipse. It is quite interesting from an astronomical and historical standpoint. There are other articles, the transit is getting more press as the date approaches. In the run up to June 5th it will be interesting to see just what the public response to this event will be.
Poli’ahu is the goddess of snows who calls Mauna Kea her home. Poli’ahu i ke kapu, recently released by Hāwane, is a tribute to Poli’ahu, the divine snow goddess of Mauna Kea.
True, the sales of the song on iTunes go to KAHEA’s Hawaiian-Environmental Alliance Mauna Kea Legal Defense Fund. This is the same group that opposes telescopes on the mountain. The Enemy? Not really. In this case I respect those who stand up for what they believe, even if I disagree. KAHEA does needed work on other fronts across the islands.
