22D, Parhelion, Parhelic Arc, Subsun, LTA, and SubParhelion
The beautiful display today gave me another treat that I didn't notice until I got home. This subsun was accompanied by a lower tangent arc, partially obscured by the plane's wing, and a faint subparhelion. It's not the most brilliant subparhelion ever observed, but it's the only one ever observed by myself, so I'm tickled pink. Add to that the parhelic arc off the left parhelion, and I'm thinking that the rest of the passengers have no idea what they missed!
