[48.13] Which Observatories have the Clearest Skies? A Comparative Analysis of 2004 as Seen by the Night Sky Live Global Network of CONCAMs

W. E. Pereira, V. Muzzin, M. Merlo, L. Shamir, R. J. Nemiroff (Michigan Tech.), Night Sky Live Collaboration

Nearly identical fisheye CONCAMs are now deployed at many major observatories as part of the Night Sky Live (NSL) global network and return real-time data to http://NightSkyLive.net . Combined, these images create a unique ability to assess and compare the relative ground-truth clarity of the skies above these observatories every few minutes. To this end, data and images from CONCAMs are used to estimate the fraction of time that stars are detectable in at least half the sky for each month of 2004. This preliminary comparison was done by visual inspection of on-line archived CONCAM images. Sites involved include Mauna Kea (Hawaii), Haleakala (Hawaii), Siding Spring (Australia), Canary Islands (Spain), Kitt Peak (Arizona), Cerro Pachon (Chile), Wise (Israel), and Sutherland (South Africa).
