Weather and Seeing Conditions

Clear Sky Clock
(If the Clear Sky Clock is on a prior date, clear your history and it will update)

The darkness level in the Clear Sky Clock takes the altitude of both the sun and moon, as well as the phase of the moon, into account.

Normally, for the altitude of the Sun or Moon at SRO, just hover over the darkness cells of the Clear Sky Clock.  However, it  will not work on the directed link above.  For this function, you need to directly connect the Clear Sky Clock, which you can do through the button below:
