Sidewalk Astronomy this weekend
Will there be sky tonight or not? It's hard to guess! The forecast calls for clear skies with foggy conditions. If the fog isn't too thick, we should have a good view of the not-quite-full Moon and Saturn from Colorado Blvd. in Pasadena. Which leads me to a great new feature linked from our website, <http://www.otastro.org/> the Clear Sky Clocks for our usual observing locations. Mr. Attilla Danko uses forecast data from the Canadian Meteorological Center to produce a graphical spot forecast of interesting weather for astronomers. The Clear Sky Clock predicts cloudiness, transparency (fog and humidity), and seeing (wavery views or scintillation) over the next 48 hour period. Here is the Clear Sky Clock for Old Town Pasadena: <http://cleardarksky.com/c/OTPsdnCAkey.html> He can explain it better than I can. Mr. Danko was gracious enough to add our two favorite sidewalk astronomy locations to the list of Clear Sky Clocks. So tonight (Friday) falls under the category of "look and see." I'll be out on Colorado in the early evening, and if it looks like there will be some sky, then we'll certainly set up the telescopes. Saturday evening conditions look a bit better, so we'll be hopeful at Library Park in Monrovia, at Myrtle and Lime. Hope to see you there!
