| The Clear Sky Clock is an on-going process. Although it is
already a very good tool, its authors, Attilla Danko and Allan Rahill, are
always working at enhancing its accuracy. You can help them do just that by logging your "Seeing"
observations at Canada/USA Astronomical
Seeing Observation Program.
