View at EarthSky Community Photos. | Todd Hull in Seoul, South Korea captured this silhouette of an owl in front of the moon on Friday night and wrote, “Happy Halloween. With cloudy skies in the forecast for Halloween in Seoul, I headed out the night before to try to catch the almost full Halloween moon. Little did I know, but I was in for much more than that: an owl (Northern Boobook) haloed by the nearly full moon—in the same frame with Mars. A once in a lifetime sight, and one you will never forget.” Glorious shot, Todd. Thank you!
