Cloud Coverage Overview Legend Various colors codes depict different aspects of cloud coverage and other criteria for scheduling continuum projects.  In short, the times when conditions are best for continuum observing are those where blue extends from the top to the bottom of the figure.  Any shade of white, cyan, or magenta indicate less than perfect continuum conditions.

Cyan Unsuitable for all others systems (LWd > 300 W/m2)

The display is divided into various horizontal bands whose purposes and color schemes are as follows:
