It might be interesting for those who are not able to attend and have a SQM
to take some readings in the direction of downtown before, during & after
the event. See if anything noticeable from outside the affected area.

Hi Shantel & all participating in the Arizona Science Center Star Party,
Thanks that you are! (And also thanks to those participating with photos =
& SQMs from other sites around the valley.)
If you're bringing a scope: Enter Heritage Square from the Monroe & 7th =
Street Gate. This link should be a map of the area =
http://www.google.com/search?hl=3Den&q=3Darizona+science+center or =
google Arizona Science Center. The official address is 600 E. =
Washington. Heritage Square is on the West side of 7th Street in =
between Washington and VanBuren. Monroe is just South of Van Buren.
You can leave your vehicle on the plaza if you bring a scope or park it =
in the science center's garage. The Science Center will validate the =
parking.
You can start showing up at 6:30 but don't be later than ~7:05ish to =
avoid the hazards of pedestrians mixing with cars!
The Science Center is supplying water.
Keep in mind some deep sky objects for before during and after the Hour =
of Darkness--Orion Neb M36,37,38, Whirlpool Gal., Andromeda as well as =
naked eye--Milky Way! Mizar/Alcor, Pleiades.
Keep this in mind as well to mention to folks:=20
We'd like to also get the message out that you can save energy, reduce =
CO2 emissions, AND help bring back the MilkyWay _everyday_ while you're =
at it by simply shielding and pointing your lights down instead of into =
the sky, this will enable you to use less wattage and less lights.
Bring a SQM and or a camera if you have one and want to bring =
them--Refer to my email of March 27th, which I've attached parts of =
below*** regarding photos & measurements. Please print the SQM document =
in the attachments if you're bringing an SQM.
After the star party, there will be a gathering at Lynn and Dorelyn's =
house near 12th Street and McDowell. We'll give directions there for =
those wanting to join us. It will be good to exchange and converse while =
everything is fresh. Thanks Lynn & Dorelyn! =20
Kind regards, and thanks! Let's make this the start of re-claiming our =
night sky.

If you have a Sky Quality Meter:
We need folks with Sky Quality Meters to bring them out to whereever =
they are and take measurements before, during, and after this event. =
You can utilize the chart (see attachments) to record your measurements =
to email to Chris Luginbuhl cbl@xxxxxxxxxxxxx and/or Katie Garmany =
kgarmany@xxxxxxxx One way to do this is to affix the SQM to a tripod =
pointed at the Zenith and take a measurement ~every 10 minutes or so =
between 7:45 and 9:15. The other option is to take measurements at the =
following three times each time measuring at the zenith (90degrees), =
45degrees, and the horizon (zero degrees), first measurements should be =
facing toward the city, then rotate yourself 45degrees to the Right and =
take the 45degree and horizon measurements, then 45degrees Left of your =
starting point and do the same. So for each of the three time periods =
you would have a total of 7 measurements to record.***=20
Between 7:30 and 7:45 pm (to avoid sunset)
Between 8:15 and 8:45 pm (Earth Hour is 8 to 9 pm)
Between 9:15 and 9:45 pm
***If you have the newest SQM, the SQM-L model add measurements at =
22.5degrees for each of the 3 positions.
Or if you can bring a camera:
Photos of Phoenix will also be useful and appreciated. So bring your =
cameras. Chris suggests taking the photos from a mountaintop, hill, or =
rise, use a tripod and shoot the same exact photo toward downtown =
Phoenix for each exposure, turn off the flash(!), point in a nice =
direction and shoot once every 10 minutes. He's thinking f2.8 with =
2"exposures. 7:30ish--9:30or so. This should make a nice series of =
photos to string together to show the before during and after effects. =
Send the photos to Chris cbl@xxxxxxxxxxxxx If you can't/don't want to =
do a photo every 10 minutes, try to take at least one for each before =
during and after time period with your camera at as near the same spot =
as possible. Be sure to indicate the location you have taken the photos =
from, GPS coordinates if possible.
Also, for those folks that will be in the same location on Friday the =
28th or Sunday the 30th, please take the same SQM measurements and =
photos as well.
