For folks in the Southern Hemisphere (Australia, New Zealand, etc.), I know the graph looks wonky -- I'll have to adjust the JPGraph directives to make it look like the Northern Hemisphere graphs.
I did check the calculated data v.s. the USNO and it looks good
check-sunmoon-data.php V1.00 - 26-Aug-2024
..using sunposa.php/USNO data for local times at
lat='-41.428945' lon='148.272474' tz='Australia/Hobart'.
Note: only USNO times coresponding to sunposa.php generated times
are displayed in the following tables
----- Sun data compare -----
Data values are azimuth,elevation

it's just that the azimuth map to a X scale that is not 40 to 320 but centered instead on zero. I'll keep trying to make it adapt, meanwhile, I suggest holding off on the update (at least the wxastronomy.php) until I can get sunposa.php fixed.
