Sunday July 14th was an excellent evening to measure a Lunar. The sky was perfectly clear and the Moon and Jupiter were clearly visible from my apartment balcony. This is generally not the case as there has been so much local construction in recent years.
The distance measured from the Moon_NearLimb to the centre of Jupiter = 16deg 1min
Sextant Index Error = 2min off
MoonHP = 55.7min
Moon Semi Diameter + Augmentation = 15.3min
Lunar Distance_apparent = 16deg 1min + 2min (IE) + 15.3min (SDs) = 16deg 18.3min
MoonGP: GHA = 52deg 40.7min DEC = 21deg 57.6minS
JupiterGP: GHA = 69deg 55.4min DEC = 22deg 10.5minS
Geo Centric Lunar Distance = 15deg 58.5min
Hc_moon = 19deg 54 min (Seen in Toronto)
Az_moon = 153deg 40.2min
Hc_jupiter = 23deg 32.6min (Seen in Toronto)
Az_jupiter = 170deg 25.5min
Ha_moon = Hc_moon + R – PA
Ha_moon = 19deg 54min + 2.7min – 52.6min = 19deg 4.1min
Ha_jupiter = Hc_jupiter + R = 23deg 32.6min + 2.2min = 23deg 34.8min
Lunar Distance_apparent_calculated = 16deg 14min
Lunar Distance_apparent_measured = 16deg 18.3min
Error = 4.3min
