Sunrise Wobble Pattern

type="html">

I'm in WI of USA.

In our area, on Jan 20, sunrise at 7:28 am by forecast, but real sunrise at 7:34 am.
On Jan 21, sunrise at 7:27 am by forecast, but real sunrise at 7:37 am.
On Feb 1, real sunrise at 7:25 am (I didn't check the forecast). For about 10 min after sunrise, the Sun's moved sliding on the horizon.
On Feb 2, sunrise at 7:15 am by forecast, but real sunrise at 7:28 am.
On Feb 6, sunrise at 7:10 am by forecast, but real sunrise at 7:20~25 am.
On Feb 8, sunrise at 7:07 am by forecast, but real sunrise at 7:20 am.

I don't check everyday, but I think above dates have relation to earth wobble. Especially, the sunrise on Feb 2 is later than Feb 1. I'm also finding the Sun a bit too far South.

Nancy's Comments: This is the wobble, as you are getting a consistent LATE sunrise, later than expected. Note that the "Italy Face" has the globe tilted so that the Sun is too far South, at sunrise, and we in Wisconsin are a bit too far North at that time too. Then we get into the "Americas Face" but only at noon over the US. You should be finding the Sun a bit too far South, also. On February 2, you literally were observing the Earth move during the wobble.
