We Saw the Total Eclipse!!!

When we awoke yesterday morning at 05:30am, we were upset to find about 75% overcast and fairly squally weather. But we got underway at 06:15 as planned, for the viewing site about 5 miles from our anchorage.

We anchored off the small motu (islet along the reef) where we had planted the measurement equipment the day before. We dinghied ashore and hiked south along the eastern shore to where the southernmost photometer had been set up. We arrived on station about 07:30 am. Full totality was not expected until 08:34am.

Dave and Lydie Checking Out the Start of the Eclipse
By 07:30, the eclipse had started, and we played around with the cardboard 'Eclipse Viewing Glasses' that we'd been issued. I took a bunch of photos of the partial eclipse through the glasses, with varying success.

"Look, there's the Eclipse!"
Lydie eventually decided to walk further south along the shore--it was much easier now as the tide was much lower than when we'd been there the day before. She ended up watching nearly a quarter mile south of where we were, and got a much longer 'totality' than we did.

It was a squally day, and we prayed that we would have a clear view of the sun during the eclipse. We did get rained on a few times, but nothing serious. Fortunately, the sun kept coming out, and we ended up with a very good view of the sun during the totality. Since I was assigned stopwatch duty, I didn't get any pics DURING the totality, but Dave ended up getting some GREAT pictures.













He took them using the camera settings that one of the scientists had told him to use, and they came out really clear and nice. Plus the Canon camera time-stamps to the second, so we have accurate times on the pictures as well. We hope that they are of some use to someone--beyond the amusement of our friends and family.

Lydie and Dave Dismantling the Photometers
We only saw about 20 seconds of totality. But we had to wait around for another hour and a half for the equipment to shut itself down. We dismantled the 3 photometers on that island, and then motored east to another motu to pick up the last one. We weren't back in our anchorage until nearly 3pm.

At 03:30pm, San Saens, the charter boat with the other scientists, anchored next to us to pick up Lydie. Then they hauled anchor and headed back to the pass, for an overnight trip to Fakarava. They will all fly back from Fakarava, and then Arnold, the captain, will take the boat back to Raitea.

The Scientific Crew Leaving
Though we'd like to hang out here for another day or two, we see a good weather window to head for Makemo tonight. So we are planning to head out the pass around 4:30pm this afternoon, for a short overnight to Makemo. If we miss this weather window, it may well be another 7-10 days before we get another good window.

Waiting for The Total Eclipse of the Sun

Current Location: SE Corner of Tahanea, Tuamotus, French Polynesia

We have been anchored here for a few days now, enjoying the solitude. We are not completely alone any more. A Canadian boat whose name we can't quite read with the binoculars, came in 2 days ago and anchored about a half a mile away. They, like us, have been mostly hanging out on their boat doing 'boat chores'. We were going to swing by yesterday in the dinghy on our way ashore, just to say hi, but we were running out of daylight before we finally got in the dinghy. Maybe tomorrow.

A third boat came in sometime yesterday. They anchored so far to the north of us that we didn't even know they were there until we saw a dinghy go by. "Where did that come from?" We had to get out the binoculars to see them.

But now we have met them. It is a boat from Dream Charters' charter fleet, with 5 scientists from France, here to study the eclipse. It is a 52-foot Jeanneau-style sailboat. They were running around in their dinghy looking for diesel fuel--they had planned to refuel in Makemo but found they could not obtain any until the supply boat came in a few days. So we sold them 10 gallons from our precious stock, and then were invited to help them out with their scientific observations.

Dr. Lydie Sichoix, Associate Professor from the University of French Polynesia, Shows Us a Photometer
Apparently, a total eclipse is a great way to measure the diameter of the sun. So their task is to place photometry devices around on the atolls to record the time and location of the eclipse. The eclipse is making a swath of totality who's northern border is just going to cut across the SE corner of Tahanea, where we are. That makes Tahanea a prime measurement spot.

So yesterday, we loaded up on their boat and went down to one motu in the extreme SouthEast end, and anchored temporarily to plant 4 Picali Photometre Solaire devices. Then they are going to leave one of the scientists with us today, and sail to another atoll 20 miles away to observe the eclipse from there (Motutunga). We will keep Lydie with us, take her to the proper spot to observe the eclipse, and then retrieve the photometry devices. When they return from Motutunga, they will take Lydie and the photometers and leave immediately for Fakarava.

Setting up the Photometers
Checking the Angle Precisely
The Photometer Set Up
It is still blowing like stink here (20+ knots) from the East. In lighter winds, we would go down and spend the night at the proper spot, but it is really rough down there. So we will spend the night tonight anchored comfortably here in our sheltered spot, and then get up early and go down at first light (about 5 miles away). The eclipse will start at about 0720 am and reach totality about 0824am here on the 11th (actually 1824 UTC).

(These calculations came from eclipse.gsfc.nasa.gov, for location 16.9871S 144.6639W))

We are just on the very edge of the path of totality, so the scientists say that we will only have totality for about 10-20 seconds. Dave is going to take our camera and try to take pictures. And the scientists gave us some plastic viewing glasses. They are similar in form to the cardboard glasses you get at 3D movies, but with much darker plastic--made for viewing solar events.

We have also been issued chronometers supplied by a professor at Yale University, to time the totality. One of the things being studied is how the irregularity of the surface of the moon (which is causing the totality) affects the eclipse, and their efforts to measure the diameter of the sun.

We are excited to actually be involved in a scientific experiment, rather than just hanging out here drinking beer!
