Astronomers Find the Calmest Place On Earth

The Narrative Fallacy writes "Live Science reports that astronomers in search of the perfect site to take pictures of the heavens have combined data from satellites, ground stations and climate models in a study to assess the many factors that affect image quality — cloud cover, temperature, sky-brightness, water vapor, wind speeds and atmospheric turbulence. They have pinpointed the coldest, driest, calmest place on earth, known simply as Ridge A, 13,297 feet high on the Antarctic Plateau. 'It's so calm that there's almost no wind or weather there at all,' says study leader Will Saunders, of the Anglo-Australian Observatory. 'The astronomical images taken at Ridge A should be at least three times sharper than at the best sites currently used by astronomers.' Located within the Australian Antarctic Territory, the site is 89 miles from the PLATO (PLATeau Observatory) international robotic observatory. The new site would be superior to the best existing observatories on high mountain tops in Hawaii and Chile, Saunders says. 'Because the sky there is so much darker and drier, it means that a modestly-sized telescope would be as powerful as the largest telescopes anywhere else on earth.'"

      The problem is getting the data back to Earth. I would assume that it would be an un-staffed observatory, in which case, you'd need to do one of the following:
      • send up a courier to swap out SD cards every few weeks.
      • set up a network connecting the station with a transmitter which has line-of-site to the Earth.
      • put a couple of satellites in orbit which are in line-of-sight to the far side of the moon, so that the data could be relayed back to Earth.

      Presumably you put the generator a sufficient distance away to minimize any disturbance to the optics, or to seeing quality. The area gets almost no precipitation and probably no animal life, so anything you lay on the ground will remain undisturbed. In this sense it seems like an ideal place to run an automated telescope, if you can get past the somewhat difficult access issue.

      Regarding the "condensing on the optics" problem, astronomers have hundreds of years of experience dealing with this issue. The simplest approach is to slightly warm the optics using resistive heaters. As long as the optics are slightly warmer than the surroundings, any water in the air will condense somewhere else. You don't want too much heating, since then you form convective air currents above the mirror that harm the seeing conditions. However with some reasonably accurate temperature sensors and a feedback controller, the condensation problem is straightforward to solve.

Granted, both Russia and the US "reserve the right" to make territorial claims in the future, but to do so they'd have to withdraw from the Antarctic Treaty (which explicitly forbids new territorial claims, and explicitly fails to either recognize or dispute pre-existing claims). I can't find any evidence that China has made similar statements (they are also a signatory on the treaty, and therefore can't make claims), but I'm sure if the treaty were broken they would try and get in on the action.

    http://en.wikipedia.org/wiki/Aurora_(astronomy)#Frequency_of_occurrence

    The aurora is a common occurrence in the Poles. It is occasionally seen in temperate latitudes, when a strong magnetic storm temporarily expands the auroral oval. Large magnetic storms are most common during the peak of the eleven-year sunspot cycle or during the three years after that peak.[citation needed] However, within the auroral zone the likelihood of an aurora occurring depends mostly on the slant of IMF lines (the slant is known as Bz), being greater with southward slants.
    Geomagnetic storms that ignite auroras actually happen more often during the months around the equinoxes. It is not well understood why geomagnetic storms are tied to Earth's seasons while polar activity is not. But it is known that during spring and autumn, the interplanetary magnetic field and that of Earth link up. At the magnetopause, Earth's magnetic field points north. When Bz becomes large and negative (i.e., the IMF tilts south), it can partially cancel Earth's magnetic field at the point of contact. South-pointing Bz's open a door through which energy from the solar wind can reach Earth's inner magnetosphere.
