Shoveling Snow in a Tropical Paradise

I shoveled snow in Hawaiʻi today.

Not the first time I have shoveled snow here. Somehow the novelty of snow in a tropical paradise never grows old. Not that shoveling snow at nearly 14,000ft gets any easier. The weekend storm left a foot of fresh snow on the mountain. As the Monday crew never made it to the summit, it fell to those of us working Tuesday to clear out the snow for access.

It was only a foot of snow? Not too bad? The snow came with 120mph winds, stripping the slopes bare and piling a three foot deep, fifteen foot wide drift in front of our loading dock and main doors. That was going to be a chore.

We needed power. The grader was working to clear the IRTF access road just above us. As the crew moved the vehicles I made a trip up to intercept the grader. At my request the driver joking asked how much cash I had. No. Beer? No. I offered cookies and the deal was made. A few minutes later the grader was clearing much of the snowdrift in our way.

A Night of Shooting in the Dark

The plan was to do some astrophotography Saturday night. The weather forecast forced a re-schedule, a winter storm arriving Saturday afternoon, Friday it was to be.

The timing proved to be excellent, Mauna Kea providing glorious skies Friday night. Clouds hovered over the side of the mountain on arrival, but there was no worry. These were the sort of clouds that would vanish with the daylight. Anxious tourists wanting to see through the telescopes repeated the same question, will the clouds go away? I answered the questions with the relaxed assurance of experience of years on Mauna Kea, and continued to set up the gear. The clouds didn’t even last as long as I expected, dissipating as the sun settled into the horizon.

Setting up at the Mauna Kea VIS means a crowd of people. Hundreds of tourists that have come to enjoy a dark Mauna Kea Sky. I was joined by Raymond, a Hilo amateur also looking to take some photos. We setup side by side in a parking space just off the patio where the VIS was setting up their telescopes for the night. We would be in the center of the crowd for a while.

Staying Late at Work

The plan was simple. Stay on the summit after work to do some nighttime scenic photography.

I was hesitant in going up after suffering my recent ear infection. The ear is vastly better, no problems with clearing the ear for several days. After two weeks absence the list of things I needed to get done on the summit was getting lengthy and urgent. Yet I worried a bit about going up. An idea… Take my own vehicle. If I have trouble I can go at my own pace without holding up the rest of the guys. If the trouble is serious I can abort and head back down.

If I did bring my own vehicle I could get in a little photography along the way. I had not really had a chance to try out the Rokinon 14mm f/2.8 lens I had bought specifically for starry sky work. Why not stay late, watch sunset and take a few photos after dark? There is snow on the summit, the weather looked promising, the Moon would not rise until after 10pm, all good things.

The plan worked as envisioned. A good day getting stuff done. Actually a rather hectic day. The filter wheel problem of TRICK found and eliminated, the heater circuit at least looked at, I think the problem is still there. Warping data recorded for a segment in Keck 2 for the refurbishment project. Some wiring on TBAD completed, still more to do. An issue with the Keck 2 interlocks that popped up during the day was dealt with. Yes, a very good day.

A minimal dinner of instant ramen, and some paperwork accomplished while waiting for sunset.

Into the cold dark I go… The combination of the Canon 6D and the fast 14mm lens is impressive. This gear will really allow me to step up my game. I was able to shoot great material under very dark conditions. Photos that had been just out of reach for me until now. It will take me a couple days to go through and process the material, but a first look is very pleasing.

Only one problem… What is this red stuff showing up in my photos? Normal airglow is green, but this is crimson red and has very distinct structure? The idea of aurora crosses my mind, almost immediately dismissed as I am standing at 20°N latitude. I step away from the camera and the light for a bit. With some effort I can convince myself that I am seeing red in the sky, at least in the darker areas away from the Milky Way. But it is fleeting, and perhaps just an overactive desire to see something.

I get home and just out of curiosity I check the planetary Kp index… What?!? We have a Kp=6 geomagnetic storm in progress! Beautiful aurora photos are being posted from the upper midwest. Reports of aurora from across much of the United States. There is certainly a dramatic storm in progress. Perhaps this is a low latitude auroral glow!

There are some references to auroral glows detected at all latitudes during strong geomagnetic storms. Is this what my camera is detecting?

It is a nice photo. You can see the glow from the lava lake at Halemaʻumaʻu, the winter Milky Way, and a research laser shining straight up from the atmospheric lab atop Mauna Loa.

Airglow or auroral glow?
