Seeking San Francisco IDA members for Dark Sky action
I have been asked if I can find a
IDA representative to participate in a stakeholder committee associated
with the San Francisco Commission on the Environment.
The committee apparently is promoted/requested by Lights Out San Francisco and American Bird Conservancy.
As I am told "The goal of the program is to reduce unnecessary night
lighting in the city of San Francisco to reduce the threat of nighttime
collisions with buildings for migratory birds, conserve resources, save
money, reduce greenhouse gas emissions, and ultimately increase
visibility of the night sky."
This is VERY early in the process of forming the stakeholder committee.
If you are interested please contact me.
If you would like to get more involved in Norther California activities please join the Cal-IDA yahoo group go to:

Cal-IDA Yahoo Group has been updated and opened to members posting in
the hope that it will increase communication and Dark Sky activities in
California. To join the group the Cal-IDA yahoo group go to: http://groups.yahoo.com/group/Cal-IDA/join (Yahoo! ID required)

millions of Americans glance into the sky in the hopes to wish upon a
star, or gaze at the wonders of the universe, only to discover their
view has been replaced by a yellow haze. And while the loss of
starlight may seem inconsequential, or just a sad reality of our
continuing development, did you know there are other critical issues
linked to light pollution?
· Light pollution has consequences for human health.
to the journal Chronobiology International, the breast cancer incidence
is approximately 73% higher in communities with higher levels of
artificial illumination at night.
David Blask, Senior Research Scientist and Head of the Laboratory of
Chrono-Neuroendocrine Oncology at Bassett Healthcare Institute (NY)
· Light pollution wastes energy.
IDA estimates over $10 billion is wasted annually on unnecessary lighting.
Discussion by: Lee Cooper, Manager of Emerging Technologies at Pacific Gas & Electric (CA)
· Light pollution harms the environment.
pollution affects all species from zooplankton to birds to sea
turtles. Hatchling sea turtles, including Loggerhead and Leatherback
turtles, find their way to the sea by differentiating between dark,
elevated areas, and the bright, flat sea surface; misdirected light
confuses this process.

co-editor of "Ecological Consequences of Artificial Night Lighting."

Of special note to this IDA Member and I am sure many others are the
astrophotographs of Wally
Pacholka. During the many years of attending the starry Night
Festival (SNF) in Yucca Valley, CA, Wally has been a
fixture. The reason for this is his long relationship with
Joshua Tree National Park and of course Joshua Tree NP has been a
integral part of SNF from the beginning. The connection to IDA is
that from the beginning SNF has included a IDA Regional
Meeting. From all reports this year was one of the
best. No doubt because of Bob Gent being back at the helm and
Teri Jackson, Riverside County Section Leader so close and supporting
the IDA activities. The activities and displays by the California
Members can be seen spread thought out the Sections Activities
page from 1989 to 2002.

unable to see the Milky Way in the sky above the place where they live.
The stars have not, of course, become dimmer; rather, the earth has
become vastly brighter, so that celestial
objects are harder to detect. Air pollution has made the atmosphere
less transparent and more reflective, and high levels of terrestrial
illumination have washed out the stars overhead—a phenomenon called
