Star-count Challenge!

[glenc]

...This worldwide star-counting exercise, now in its third year, is a satisfying and worthwhile activity that you can do alone or with your family and friends. In the process, you'll be helping scientists gauge the extent of light pollution. Here's how it works:
First, determine your latitude and longitude. You can get these easily using our online almanac (http://www.skyandtelescope.com/observing/objects/javascript/3305541.html) or from various online map sites like ACME Mapper (http://mapper.acme.com/).
Next, go outside on some clear evening during the next two weeks, look [north], and determine the faintest stars you can see in Orion. (Important: make sure no nearby lights are hindering your view, and give your eyes at least 15 minutes to adjust to the darkness.)
If you're handy with star charts, just use one you already have to determine the faintest stars you can spot in Orion. Or you can download and print out the four-page GLOBE at Night activity packet (http://www.globe.gov/GaN/GaN2008ActivityPacket_Family.pdf), which has simplified star maps that you can used to match what you see in the sky...

These three SkyMapPro maps show Orion at about 9pm with stars to mag 5, 6 and 7.
Notice the stars near the middle of Orion's belt in each image. (epsilon Ori)

At 11pm DST last night my mag limit was 6.

I downloaded the raw data a couple days ago and had a look through. After noting that they discarded my data from last year, I won't be bothering this time around. Angelica Lopez did manage to get all 21 of her reports in, though :lol: (search the raw data if you have to know)
