Dzhanibeko effect and axial procession.
Discussion
https://sciencegifs.csullender.com/2017/07/01/The-...
A late night discussion on the relative position of the sunrise locally raised an interesting point, I had noted that the sun used to rise between two buildings outside my kitchen window when I moved in almost 10 years ago but now the sun never rises there,
Its now rises behind the right hand house by either a lot or a little, I don't know when it stopped rising between the houses but it definitely didn't do it at all last year because we had noticed it and were waiting for it to line back up again.
We moved in in April of 2015 and it was commented on by both my wife and I as to how nice it was to get the sun up right into the room first thing.
We have axial procession as the Earth goes about its travels but that should take around 26000 years according to the books.
If my admittedly anecdotal observations are to be trusted am I seeing axial procession to the extent that the sunrise has shifted ?
The other (more doomsday) question our discussion raised was given the wobble could there have been a "flip" or could there be a flip according to the Dzhanibeko effect ? see link above.
If it could happen would it be slow and survivable or an utter catastrophe for everything on the planet ?

Fast and Spurious said:
It's axial precession.
What you're observing can't be due to that though.
Why not? I'm northern hemisphere, far south West cornwall by the way. Clear uninterrupted view from the window for as far as the horizon over ground. What you're observing can't be due to that though.
Whilst googling I found a video from 11 years ago that I found interesting.

They describe a similar observation.
