Tucson International Airport (805 m):
Temperature = 10 degrees Celsius
Relative Humidity = 28 percent
Noticeable haze
Magnitude limit at 8 degrees altitude with 55 power in C-8 telescope, before onset of twilight = 10.0
Topocentric and local time values from “Accurate Times”:

Relative Altitude = 6.62 degrees

Crescent width = 11 arc seconds
Illumination = .55 percent
In order to practice for more difficult observations, the first attempt at viewing the crescent was made after it had risen to about 8 degrees altitude (above the mountains to the east).
Nothing was seen, despite being focused and on the correct FOV.
