The GLOBE project, recently written up in the April 2007 Sky & Telescope 
(pg. 42), suggests people look at Orion and note how many stars can be 
seen visually (unaided eyes) at various locations during the period 
March 8 through 21.  Details at this web site:  http://www.globe.gov/GaN/
It would be interesting to try this at locations we use around the 
state, both urban/suburban and "dark sky", and possibly compare against 
SQM readings taken with an LP meter....
(We might have to add some stars, to get down far enough ??) :>))
(Actually, charts are supplied down to 7th magnitude.....)
Below is attached the memo as forwarded from the Meade 4M group.

Equipped with only your eyes, you can join other stargazers in a 
worldwide effort to assess light pollution.
A team of astronomers and environmental scientists wants you to count 
some stars this month as part of the GLOBE at Night project, an effort 
to gauge the extent of light pollution worldwide. The task is simple: 
determine how many of Orion's stars can be seen on clear, moonless 
evenings from your home or observing site, then report your findings to 
project's website <http://www.globe.gov/GaN>.

Conceived by staffers at the National Optical Astronomy Observatories in 
Tucson, Arizona, this ambitious endeavor is managed by the University 
Corporation for Atmospheric Research and Colorado State University. 
GLOBE stands for Global Learning and Observations to Benefit the 
Environment, a program to involve primary-and secondary-school students 
in scientific activities worldwide.
