Earlier this week, I rang in the new year while on the job, helping observers commission the DESI spectrograph on the Mayall 4-meter Telescope at Kitt Peak National Observatory. Looking back, I see I rang in eight years of the last decade at the observatory. So, working on New Year’s Eve is getting to be something of a tradition for me.
Working at the observatory on New Year’s Eve is much like working on any other night of the year. It all starts out with me evaluating the weather. In the photo, I’m standing in front of the Mayall, watching the sunset. Throughout the week I had watched a forecasted storm for the night get downgraded to the point that we expected reasonable observing conditions. The night actually arrived with dark clouds and light snow. Not only was this unwelcome for observing, but New Year’s Eve was the last night of my shift and I didn’t relish the idea of driving on snowy roads.
The poor weather didn’t keep us from our commissioning work. On an instrument where 5000-robotic fibers must be precisely aligned with targets on the sky and then send the light from those targets to ten spectrographs, there’s still plenty of work that may be accomplished with the dome closed. We started with some spectrograph calibration tests, trying to answer whether it matters where the telescope is pointed when we calibrate the instrument. There was some concern about whether or not twisting of fibers at different telescope orientations might make subtle changes to the light going through them and affect the measurements we hope to make. This is important to understand and characterize before we start making measurements.
Another job we had was to test a camera that looks at the fibers on the telescope. That’s how we know the fibers are on the correct objects. We can test this camera because DESI includes some fibers that can be illuminated. This means the fiber view camera can see the position of some fibers even when we’re not looking at the sky. The telescope itself is big and flexes as it points around the sky. Understanding how objects appear on the fiber view camera depending on where we point is also an important job. We can do a lot by pointing the telescope in the closed dome with the test fibers illuminated.
Testing a new, complex system also uncovers software bugs and errors in procedure. The lead software developer on this project is fond of using barnyard sounds like a chicken clucking or a cow mooing when an error occurs. So, these sounds do occasionally intrude into our work, which means the software people need to debug code or help observers refine procedures. This is also productive work for a cloudy, snowy night. I’m also convinced that I need to find a way to work barnyard noises into some future high-tech science fiction space opera!
At 10pm, we tuned into the live feed from Times Square in New York to watch the ball drop while we worked. At midnight, we took enough of a break to toast the new year with mugs of coffee. Kitt Peak National Observatory is on the land of the Tohono O’Odham, so no alcohol is allowed, even if we weren’t working.
When the decade started, I thought of myself as “the temp” on the operations staff at Kitt Peak. I returned to Kitt Peak after nearly fifteen years to help the observatory with a staffing challenge and stabilize my income long enough to achieve some personal goals. Ten years later, I’ve achieved most of my goals, but I still think of myself as “the temp.” It’s an attitude that serves me well.
In the current political climate, I can’t guarantee my job will always be funded so I don’t take for granted I’ll have this job for an indefinite period of time. More importantly having the attitude of being “the temp” assures that I always feel free to speak my mind when needed and avoid self censorship, which is important in a job where I’m responsible for the safety of visitors. Also like any good temporary employee, I want to stay in the good graces of my employers, so it assures that I always try to do my best and constantly hone my craft.
As one decade finishes and another begins, I’m thankful to have a good and interesting job expanding humankind’s knowledge of the universe, but I also stand ready to take on whatever challenges that universe decides to throw at me in the coming decade.
