With the start of March the observatory known as JAC is no more. The Joint Astronomy Center ran two telescopes, the United Kingdom Infrared Telescope (UKIRT) and the James Clerk Maxwell Telescope (JCMT). Both telescopes have been transferred to new management and will continue to pursue science.
You can get more details on Tom Kerr’s blog A Pacific View.
I would also suggest you take a few minutes and enjoy some beautiful time-lapse to celebrate the achievements of the JAC…
In past years the club has toured the various optical observatories on Mauna Kea. Telescopes like Keck, Gemini and CFHT represent some of the largest optical telescopes in the world. There are a set of telescopes on the summit that often get overlooked, the submillimeter observatories. CSO, JCMT, and SMA all operate beyond the infrared in the submillimeter wavelengths of 0.3 to 1.4mm. These instruments enable the study of the cold and dark universe. The vast clouds of gas and dust than make up so much of the cold material between the stars and galaxies. The raw material from which everything we know is created, and to which we will return one day when the Sun has exhausted its hydrogen fuel.
Personally I had never visited these facilities, not during my seven years on the mountain. This is something that had to change. I suspected that this was true of most of the West Hawaii Astronomy club membership. It is even more imperative in that one of the facilities, CSO, is to be decommissioned and dismantled in the next few years. Thus the goal of visiting at least a couple of the submillimeter facilities to see the other side of Mauna Kea astronomy.
When arranging the tour I contacted all three submillimeter facilities on the summit. I would have considered getting two out of three a success, I knew that there was no way I would manage to get all three scheduled for a single day. The submillimeter observatories have much smaller staffs than the large optical telescopes like Keck, thus providing a tour to a visiting group is much more difficult. In the end all three observatories were able to provide a tour on the same afternoon, something I am still surprised about. A great deal of gratitude is due to the folks who drove up the mountain on a Saturday to give our group a wonderful tour.
