[AZ-Observing] Re: SQM Readings

     The relatively bright readings at 2000 MST result from there
still being a bit of twilight at that time.  The gradual decline
through the later evening hours comes mainly from the increasing
galactic latitude at this time of year.  If typical, it looks as
though the Flatiron site is medium-dark, whereas the other two
(Hovatter, KOFA) are as dark as you'll find anywhere, especially
KOFA obviously.  Nice to know that spot is as dark as it is
despite the proximity of Yuma.  Still only a 7/10 site?   B-)
