"I'll try again now realizing it is UT not local time and remember to read the details very closely.
I realized the issue when I was trying to picture where the sun would be in my mind relative to the azimuth and had the Aha! moment then because a Z of 99 at 14:00 local time does not make sense. The sun would be in front of me not behind me at 14:00 local time. "
But wait, didn't you in fact do it right? You recall in the setup that I mentioned the direction you were facing when you did that first sight of the Sun was towards the east. And you got an azimuth in the east. Maybe you did the work properly, and the only problem here is that you were imagining a different time in your head.
PS: Never use zone time (local time) in celestial navigation! Apart from stupid exam questions, you can always work with UT (and UT only) in the real world. Decades ago, wearing a spare watch set to UT might have seemed a luxury. No more. Get one. Set it. Check its error every now and then.
