> In addition to not seeing a lot of starlight this Autumn/Winter, it seemed
like we're also not seeing a lot of sunlight.  Here is a table of the last
few months of data for percent of possible sunshine from the Phoenix NWS
office, with a comparison to the averages and lows since 1896.  The daytime
cloudiness has been bad, but not extremely so.

to win 70 games when they were midway through the season.
