    Sky Information Reports

    For those of you who who are now watching the winter skies roll in, you
    might want to subscribe to the clear sky clock. It e-mails me when ever
    there are favorable viewing conditions. For those of you who don't live
    in the pacific northwest, you have to understand that once November
    comes here, getting a look at the sky can be rare. We once had 29 days
    straight with no visible sunlight. The page sends you am e-mail when the
    viewing conditions are favorable, and you can set the parameters.They
    seem more accurate than the general weather weather.
     I like it as I can make sure I have some time to set aside in the
    evening if I know I have some clear skies coming up. Sometimes I set up
    my telescope too. This summer I had many fine nights observing the moons
    of Jupiter, and trying to figure out how the navigators of old used them
    to tell exact time.  I know the theory and have the tables, but still
    have not worked out the practicle bits. Is that Io or Ganymede. I've got
    it...no wait the image is inverted in this telescope.
    Oh, on the plus side of the Pacific Northwest is we have no real freeze
    up out here. Most people only take their boats out for maintenance.
    Many people cruise the gulf Islands and San Juans all winter with a nice
    diesel heater. It's not exactly the Gulf of Mexico in the winter but is
    is nice.
