If it flies on the 31st it will be about 10 minutes before sunrise.

There is an instantaneous launch opportunity at 7:02 a.m. EST (1202 GMT), about 10 minutes before sunrise Sunday.

Possible static fire as well.

SpaceX has raised a Falcon 9 rocket vertical on pad 39A at the Kennedy Space Center in preparation for a possible test-firing Friday, followed by a launch set for Sunday with the next 60 Starlink internet satellites.

SpaceX appears to have aborted a Falcon 9 static fire test on pad 39A this morning after loading propellants into the rocket.

The launcher is packed with around 60 more Starlink internet satellites for liftoff in a couple of days.

How many days can this be delayed before the staging at altitude is in the pre-dawn dark and "the show" is diminished?
An exact answer lies at the intersection of orbital mechanics and spherical trigonometry, a pretty rough neighborhood.

Ms. Tree and Ms. Chief will head direct to the Port of Morehead City, NC, to wait for a date for Starlink, which seems to be delayed.

Fairing Catcher departure suggests the delay won't be too long.

That should be ~30 minutes before sunrise at the Cape and perhaps a few minutes before "first light" (astronomical twilight?).
The rocket could enter sunlight during the first stage burn at something like 50-60 km altitude.
(A precise answer is at the intersection of orbital mechanics and spherical trigonometry, a tough neighborhood.

)
Could make for a nice display at staging.

If the booster recovery weather doesn’t improve, it could get bumped for a couple more days.

It's pretty much guaranteed, unless SpaceX decided to expend the booster. Neither ASDS is currently on its way to the landing zone, so Feb 1 isn't feasible anymore.
