A Construction Cam for TMT
Not a hard job, but someone has to do it… Hanging off the weather tower again. This time all I am doing is taking pictures!
Paul and Fred from the the TMT telescope are walking the perimeter of the TMT site with a large white pole. At a few preset points they call me on the radio and I snap a couple photos. I spend the few minutes between each location just enjoying the view, or adjusting the climbing harness to find a less uncomfortable pose. At least the weather is quite nice.
The camera will most likely be mounted on the Keck weather mast. The location offers power and communications along with a secure mounting point. What we learn is good news, from the mast there is a clear view of the complete TMT building site
What remains to be done is the paperwork. First we must seek and receive approval from the Office of Mauna Kea Management. Any changes to the outside of any of the facilities must be approved before work begins. I have done this in the past whenever I modify one of the weather instruments. Usually not a major hurdle, but one that must be done right.
I have supported the TMT in a number of small ways. It will be exciting to watch the construction, we have a ringside seat at Keck!

Mercury at Inferior Conjunction
Today the planet Mercury passes through inferior conjunction, passing between the Sun and the Earth. In a week or so the planet will again be visible in the dawn sky, climbing higher each day. Maximum elongation will occur July 29th.

Postcard from the Reef – Unidentified Flatworm
It was small, but I was looking for small, scouring a reef wall at Kua Bay. At first glance I hoped I had found a nudibranch, a closer look revealed a flatworm. A pretty little creature moving quickly across a sponge covered surface. I did not recognize the species, not one of the usual flatworms we see by day. Certainly not another fuchsia flatworm, I had lost count of those early in the dive.
I am not alone in not being able to identify the species. It was not in the book, I had to search the websites before I found any reference to a matching species. The reference on Hoover’s website came without an identification, merely a genus name and a description that perfectly matched the flatworm I had found. Active by day on a shaded wall… Check. Found at 15-20ft… Check, more or less, found at 30ft. Reported from Maui by a known expert in the field Cory Pittman.
The worm does resemble a species known in Indonesia, the Philippines and the Mariana Islands, Pseudoceros bimarginatus. There are some differences in the photos as well. No clear answer, best leave this ID to experts. I have forwarded my photograph.
Thus my identification remains… Pseudoceros sp?
