Stephen James O'Meara's Secret Sky: Readers report 2009

September 2009: From ice crystals to a cluster's heart, I've read about some interesting observations.

Tunç Tezel captured this arc display in 2005. Ice crystals had to align just right in the atmosphere while the Full Moon sat at 65° altitude.
