While wave is generally best in the mornings, great flights may also be made in the afternoon. However, official sunset time must be kept in mind.  Landing after official sunset is not safe and disqualifies the flight for consideration as a leg of a badge.  From high above Mt. Mitchell, the sun may appear well above the horizon, but if you look down, you may see the ground in deep shadow.  Plan your descent with sunset in mind. On February 26th, sunrise is at 7:03 AM, and sunset is at 6:19 PM; by March 7th, sunrise is 12 minutes earlier, and sunset 9 minutes later.
