There are a number of telescopes on Mauna Loa which have not been removed, just this sensor.

I don't want to touch that flame hazard with a thirty-meter pole, but, just to clarify context:

- The entirety of the Mauna Loa observatory, which is operated by NOAA (weather guys), is being shut down;

- The vastly larger Mauna Kea observatories, hosting dozens of federal and international clients, is unrelated

Ah, thank you. I might have gotten the two mixed up.

Seconded. The facility on Mauna Loa is the Mauna Loa Observatory which is atmospheric sensors and a solar telescope. The famous telescopes are on Mauna Kea (source: I grew up in Hawaii and worked for one of the telescopes, CFHT)
