Redoing Greg Rudzinski’s eclipse observations with actual temperature and pressure data extracted from the lunar form:
Pressure: 29.98 inches Hg = 761.492 Torr = 1015 mb
Temperature: 75 °F
Height of eye: 0
Index error: 0
increases Sun’s Ho by 0.1’ and improves the celestial fix to:
Lat: 34° 34.7’ N
Lon: 119° 03.7’ W
Distance of celestial fix from GPS position: 26 NM (better by 5 NM)
