CLEAR SKY CLOCKS WITHIN 100KM OF MANHATTAN
Attilla Danko, of Canada, compiles forecasts for astronomy sky conditions, called Clear Sky Clocks, for hundreds of sites in North America. The clocks are colored graphs for the 48 hours following the instant moment for cloud cover, seeing, transparency, temperature, and other items. The two clocks below are for NYSkies starviewing sites in Central Park, Manhattan, and Floyd Bennett Field, Brooklyn. Here is the explanation of the colors in each bar in the clock.
The list below for clocks within 100 kilometers of Manhattan is adapted from Danko's website. 'Preview' is the 'cloud cover' and 'transparency' bars from the complete clock, with hours lined up with those on the two NYSkies clocks above. Click on the town to see details about its clock on his website. Please mind that the clocks generally still use oldstyle measures, not metric. Be careful when interpreting their readings.
Clear Sky Clocks within 100Km of New York City
While the sites are only ten or so kilometers apart, their hour-by-hour forecasts are not the same. It is a common experience that an astronomer in one part of NYSkies land receives a quite different weather from his colleague elsewhere in the territory.
