The instruments were warming up. Liquid nitrogen exhausted, cooling interrupted by loss of power, the cryogenic dewars had begun to warm. Recovering instruments takes many days of vacuum pumps and re-cooling to restore function if cooling has been loss. Other problems caused by the storm and power outages plagued the summit, some systems not responding to remote queries.
Keck Observatory covered in heavy iceOn Friday, the crew had abandoned early in the day in the face of deteriorating weather conditions. With the storm raging, no one had made it to the summit on Saturday. We all watched as remote weather instruments reported sustained winds of over 100mph and gusts as high as 134mph. With the wind came freezing fog, a thick coating of ice forming on every surface. The snowplow crews did not even try Saturday, it was just too dangerous.
Sunday offered at least a hope of making it to the summit. The storm had abated and beautiful sunny skies appeared over the summit. We readied for an attempt at the summit of Mauna Kea. As the engineer on call I would join the support techs at the summit. Maybe we could salvage something from the chaos.
Not a great deal of snow, maybe an inch or two rearranged by the winds. More snow is expected over the coming few days before this storm is over. Where to find the heaviest snow on the mountain? Puʻu Poliʻahu of course, just look at the images below.
This is the first winter storm that our new weather mast camera is operating, since I bolted it in place a couple months ago. It is great fun to have a full pan-tilt-zoom camera available during weather events like this.

It is currently snowing on the summit. Not just a dusting this time, but a real blanket of white on the mountain. Poliʻahu has returned to the summit. The forecast is calling for up to three inches of white before tomorrow morning.
We just got word that the Keck summit crew is abandoning the summit. They are leaving before the conditions get worse.
A photo from a UKIRT webcam is below. I would post one from our Keck cameras, but the camera windows are covered with blown snow and ice. I have a new all-weather webcam, a full pan-tilt-zoom unit to install, but it is still sitting in a box at the summit. Personally I am not planning being up until Wednesday, I wonder if the snow will still be there, fresh snow on the mountain is always pretty.

The Mauna Kea summit at night, panorama of seven frames with a Canon 6D, 20s @ ISO6200 and Rokinon 14mm f/2.8 lens
It may look small, but this image is anything but small, click on it to find out. The panorama is assembled from seven frames, with final dimensions of over 12,000 x 2,000 pixels. The version posted here is a bit smaller, only 4,000 pixels wide. While it is a big image it does not really come close to the effect of actually standing there beside the camera. Also missing from the photo? The biting cold wind.
The image includes ten telescopes, two planets, two galaxies, two meteors, four volcanoes, and innumerable stars.
Following the approval of a sublease on July 25 by the Hawaii Board of Land and Natural Resources, the Thirty Meter Telescope (TMT) announces the beginning of the construction phase on Hawaii Island and around the world throughout the TMT international partnership. Contingent on that decision, the TMT International Observatory (TIO) Board of Directors, the project’s new governing body, recently approved the initial phase of construction, with activities near the summit of Mauna Kea scheduled to start later this year.

The final approval from the Board of Land and Natural Resources—the last step in the sublease process—allows TMT to begin on-site construction on Mauna Kea, home to many of the world’s premier observatories.
“It has been an amazing journey for TMT, from idea to shovel-ready project,” said Henry Yang, TIO Board Chair and Chancellor of the University of California Santa Barbara. “We are grateful to the Gordon and Betty Moore Foundation, the Hawaiian government, its citizens, and our project partners in bringing this important astronomical science effort to fruition. It is also my rewarding experience to work with so many community friends, University of Hawaii colleagues, and officials on both the Big Island and Oahu in this journey.”
