Covid shots
#3
Boy, do I feel silly... I complained about being 5 miles off when its my brain that was 5 miles off... I was using the 2019 almanac for the reduction.  I downloaded the 2020 one and my lop gets much closer.  however the zn azimuth now runs a bit further away.  ill have to take some more shots tomorrow and be super careful.  I got in a rush this afternoon when after I discovered the almanac wrong year I took a hurried sun shot as it was diving in and out of the clouds.

Ill update all this again.  below you can see this mornings shot and the reduction with the wrong almanac (2019).


ust did a sun shot this morning - 5 nm off again.  Before I took the shot I checked for index error using the sun... spot on... no error.

Dec 22 23:48:23
Clock error +2
Corrected time gmt 23:48:21
Hs 46 24.4
/2 = 23 12.2
Altc +14.0
Ho 23 26.2

Gha 165 20.5
Inc +12 05.3
Tgha 177 25.8
Ap long +124 34.2
Lha 302
Dec -23 26   d=0
Tdec -23 26
Ap lat 10 contrary

Hc 24 22.0     d= -24    Z 121
Diff = 26/60 × -24 = -10.4
Thc 24 11.6 - ho 23 26.2
Intercept 45.4 away
Zn 121

These are my figures.  Ive been over them and over them.  My AH is open so no glass. Time checked with wwv. Checked gps again... n10 17.5  e123 57

The lop is 5 nm past the gps fix.  Always 4 or 5 nm long or short.

Merry Christmas to you as well and thanks.
