One Star at a Time, in partnership with Astronomers Without Borders and Starlight Initiative, is in its very beginning stages of registering all observing/stargazing locations as StarParks in the Global StarPark Network.  Our primary goal is to unify people across the globe for the reduction of light pollution, and to show governmental leaders a listing of places around the world that people gather to enjoy starlight... so they can see that people care about starlight... and they should too!  This list can also double as a guide for eco-tourism and connecting families to local observing areas and associations. 
One of the goals is to monitor and track the night sky quality above them. We are endorsed and supported  by the United Nation's UNESCO MaB programme.  (see website for other language translations). 

Please register your stargazing sites at www.onestar-awb.org   

We will be launching a major campaign soon with an optimistic goal to register a majority these sites within one year's time -- before July 2012.

It will  be very helpful to know which system is best to use to record the skyquality of these sites... and implement sooner the better. .. so we can collaborate synergistically with your efforts. 

Trying to make good use of the 150th anniversary of amateur astronomy in the western hemisphere.  Chicago Astronomical Society happens to be the first astronomical society founded in the western hemisphere in 12/12/1862.   The Astronomical League Conference (ALCon2012) will be hosted in Chicago July 4 ~ 7th.  We will work very, very hard to raise awareness of light pollution and hopefully secure resolutions for the reduction of light pollution.  

Interested in organizing 5K global runs in multiple cities across the globe called "Run for the Stars ~ RUN like you mean it!" for July 4, 2012.  This is to build public awareness and raise money that would stay locally to make a StarPark and/or retrofit bad lighting into dark-sky friendly lighting and/or create an exhibit in a local museum or planetarium about light pollution.

We will be asking astronomical societies to contribute material in behalf of their local organization for a commemorative book entitled: "Celebrating Starlight, 150 years of amateur astronomy".  

Please contact me during this brainstorming time... so we can create the best plan to succeed. 

Thanks for caring about starlight preservation!  This is the year to unify... We can put to good use all the lessons we learned in how to collaborate and network during IYA... and apply it for the best starlight preservation campaign the planet has ever seen.  What do you say??
