When you want to see the stars, find someplace dark
Folks sometimes get a little perturbed when MKSS closes the Mauna Kea summit road. Everyone wants to go up and see the snow. Yes, the road is closed right now, for good reason, there really is no accessible road on the summit at the moment. Not taking my word for it? See for yourself…
The storm is raging at the summit. The wind is howling and freezing fog is coating everything with ice. The webcam images are mostly blocked as ice covers the camera windows, but I can still see out of one side of MastCam towards the Keck 2 dome.
Just received word that our day crew will not attempt the summit, they are leaving HP and headed home. The rangers report snow drifts on the road at fairly low elevations and the snow plow crews will not attempt to clear the roads until the storm abates. Looks like we will lose cooling on some of the instruments as the liquid nitrogen runs out.
It snowed much of yesterday and well into the night. The result? Probably about a foot total at the summit, the Mauna Kea rangers report drifts of up to two feet in places. I am scheduled up top tomorrow, maybe some more photos?
It is snowing pretty hard on the summit of Mauna Kea right now. There were a few inches from the previous days, looks like quite a bit more by tomorrow…
The storm that deposited a heavy layer of ice on Mauna Kea has kept Keck Observatory shuttered for a week now. The last night we observed was New Year’s Day. Despite clear skies, there was just too much ice on the domes that could come crashing in on the telescope if we attempted to open. For a few days the Keck II dome was frozen in place by a pile of solid ice against the lower skirt.
We just got word that day crew, with a little solar help, has cleared the worst of the ice from the domes and we will be observing tonight.
This photo is getting a little comment, no surprise, it is hilarious. When I stopped at park two to look around I had no idea and when I saw it I broke out laughing. Alone on the side of an ice covered mountain, laughing loudly with no one to hear but the wind…
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.
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.
