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. http://clearskyalarmclock.com/v2/ Bruce Hamilton Vancouver, BC --~--~---------~--~----~------------~-------~--~----~ Navigation List archive: www.fer3.com/arc To post, email NavList@fer3.com To unsubscribe, email NavList-unsubscribe@fer3.com -~----------~----~----~----~------~----~------~--~---
