Anchorage wobble proof

[Gerard Zwaan]

I had been watching Grumpy Moose and noticed that it was doing a lot of alternating between lightness and darkness this morning. I’ve seen that on other webcams, but it has been more dramatic in Alaska. The sun finally rose at 9:10 am. Well, it’s supposed to rise at 7:16 am in Anchorage, Alaska. Are my calculations accurate? Is the wobble more obvious at higher latitudes? If this is true, it’s fairly stunning. [and from another] http://www.allskycam.com/u.php?u=456

In addition to the Earth wobble allowing northern Alaska to see the Sun rise at midnight, temporarily, it is now causing a late sunrise for southern Alaska at Anchorage. If at midnight in Alaska the globe is tilted, a lean to the right, such that the N Pole is pulled toward Europe which is having a noon Sun at the moment. At sunrise in Alaska the globe is tilted to the left, so that Alaska is leaning away from the Sun. The wobble is indeed becoming more extreme, for the sunrise at Anchorage to have a two hour delay. This is supported by recent documentation from Wisconsin, which shows the sunrise there a full 25 minutes late during the month of August. All this is of course potentially leading into a severe wobble.
