Gift idea

Here's a chance to give someone a gift and do something to help conserve the night at the same time: give them an IDA t-shirt!

There are 3 different styles to choose from (the one pictured here is my favorite), and the proceeds from all three will go to support IDA's work, such as managing the International Dark Sky Places.

Submitted photos

I have some photos to share taken by friends of the blog. First, a photo of the skyglow caused by poorly shielded lamps at the Great Leighs Racecourse in Essex, United Kingdom:

Liz Perkin (@riverperkin on twitter) snapped this photo of lamps that don't prevent animals from getting inside:

This of course slightly reduces the light that gets to the ground, and also greatly increases the amount of light that gets emitted into the sky. In the worst case, lamps that let arthropods inside can get downright gross.

Lastly, a photo by Roland G. Dechesne of the Royal Astronomical Society of Canada:

Moon phase calendar for 2016

Loss of the Night app user Andrew Cool from Australia has once again produced his very cool calendar of the phases of the moon in 2016:

Northern Hemisphere moon phases, by Andrew Cool

You can download his original images in low, high or poster quality resolution on his SkippySky website. He also has a Southern Hemisphere calendar. Andrew says:

Please feel free to download the calenders. Print them by all means, but I do ask that you play nicely and retain the discrete Copyright information in each image.

If you find that the Calendars are useful, I'd be very happy to receive a small donation via PayPal to help keep the SkippySky website and my single home PC running.

Use the PayPal buttons on the website at www.skippysky.com.au

If this is your first-ever visit to the blog, welcome! The blog is about a citizen science app called "Loss of the Night". We need your help to understand how changes in street lighting technology are changing the night sky. You can read our introduction to the blog here, and instructions on how to use the app here.

There's lots more to see, including:
You can see bring up our entire photo series via this link, and all of our posts about the moon here. Thanks for visiting!
