On EarthSky’s Facebook page yesterday afternoon (May 14, 2013), we received many, many photos from U.S. East coast residents (New Jersey, New York, Pennsylvania) showing a beautiful halo around the sun. Did you see it? The photo above is from Jay Herbst. The next two below are from John Zenkus. The final photo on this page is from Steve Scanlon. But there were lots more on our Facebook page; if they haven’t moved too far down the page yet, you might still see some there by clicking Recent Posts by Others.
