I just got up at 9 and it had just turned light. By 4 it should be getting dark. Felt the quake as my husband some me up and we are over 400 miles from Anchorage.
You can go to the USGS earthquake site and report that you felt it.

As an aside, when I zoomed in to the Anchorage area, it shows 45 total quakes in and around that area for the last day, and two within the last hour. All within about a 15 mile radius of the big one.
