Don’t forget to adjust times to your time zone, the event is more or less simultaneous across the country. Midnight to 0130 in Pacific time zone (for the totality phase) equals 0100 to 0230 in Mountain time zone, 0200 to 0330 in Central time zone and 0300 to 0430 in Eastern time zone (which looks largely out of luck anyway due to widespread cloud). Some penumbral darkening will be visible about an hour either side of my time ranges above, mid-eclipse is about 0042h PDT, 0142 MDT, 0242 CDT or 0342 EDT. At mid-eclipse you should easily be able to spot Mars off to the right of the darkened Moon and the bright star Spica just below the darkened sphere.
If you happen to be in Alaska or Hawaii, better take a look right after sunset.
