I had trouble opening this page. But for those who have issues with the page, here is a brief summary. (finally got it open through safari, weird)

The article describes the discovery of a rare atmospheric phenomenon known as "Bouguer's Halo" at Summit Station on the Greenland Ice Cap.

This halo is the simultaneous appearance of a fogbow and a 22° halo, which was captured on camera by veteran optics observer and photographer Ed Stockard after being alerted by Jari Luomanen, who watches the webcam installed at the Station. The article also discusses the debate surrounding the impact of automatic cameras on discovering new halos and the importance of having experienced and dedicated observers to quickly alert local photographers.


Haven't seen any light pillars this winter - but they are quite a beautiful (and slightly spooky) phenomenon
