Station report
Sundance 8 NNW, in 5 sheets
Drawn from its report of Oct 15, 2026, 9:00 PM local time, in the manner of the Field Book, and opened beside the plates that explain each part of it.
28.9 F with a dew point of 21.0 F, 72 per cent relative humidity. Air lifted from the station would cool to its dew point, where cloud forms, about 1,800 ft up.
At 5,792 ft above sea level, 19 per cent of the atmosphere's air lies below the station. The standard atmosphere puts the pressure there at 24.17 inHg and the temperature at 38.3 F; it reports 28.9 F, 9.4 F colder than standard.
On Oct 16 the noon sun stands 36 degrees above the horizon at 44.51 N, and the day is 10 h 48 min long. Level ground there takes 59 per cent of the noon sunlight a surface facing the sun would.
