    Orientation of Orion's Sword
    From: David Pike
    Date: 2022 Feb 5, 01:49 -0800

    Over the next few days, I’ll be mainly observing the Moon’s horns, but last night was so bright I couldn’t help taking another look at Orion’s Sword.  Please will some kind person check out my calculation of the Sword’s orientation to N-S on the Celestial Spere.  As Mintaka is on the Celestial Equator, I’ve used plane trigonometry.

    From Air Almanac 2022
    Hatysa (Iota Orionis)      Dec S 5° 53.9’      SHA 275° 52.3’
    Mintaka (Delta Orionis)  Dec S 0° 17.1’      SHA 276° 43.0’
                                  Delta Dec    5° 36.8’  D SHA     0° 50.7’

    Orientation = Tan-1  50.7/336.8 = 8.56° East of North   
    Thanks.  DaveP
