Globe at Night Light Pollution Survey for February 12-21

Northern sky at 10 pm local daylight saving time in Australia showing Orion.

Globe at Night, the international light pollution survey, is running its second survey this year from February 12-21. There are two more to come March 13-22 and April 11-20. Visit their websit e for easy to follow instructions and charts to estimate how dark your sky is.

Basically, an hour or so after sunset (8-10 pm) head out, look to the north to find Leo, (if you are in the northern hemisphere) or south to find Crux (for us southern hemisphere types) or Orion (for everybody) then check how many stars are visible, and report your observations. It's a great excuse to get outdoors and look at the sky. You might even see the International Space Station or an Iridium flare.

This year you can submit your results a smart phone or tablet. To do this, you can use the web application at www.globeatnight.org/webapp/. Globe at Night is also on Facebook and Twitter.

Thank-you for promoting the GLOBE at Night campaign. Please note that you can also report your observation(s) from your computer later after your observation at www.globeatnight.org/webapp/. And if you have a smart mobile device like a smart cell phone or smart tablet, you can report as you are observing (by using the same URL address). There will be 2 more 10-day campaigns in March and April. Clear and dark skies, Connie
