>> Since June is almost here, would it be possible for you to post similar >> data for June? Bernie Sanden did this in quite some detail several years ago in re planning the "best" date for the Grand Canyon Star Party. I have a printed copy of this, but perhaps Bernie has it stashed away in machine-readable form somewhere. If I recall correctly, the bottom line was that the third week of June has a quite high probability of being clear. \Brian --- This message is from the AZ-Observing mailing list.
