Recovery technicians are experimenting with a fairing half today. I can also confirm that Ms.
Chief will not take part in the upcoming Starlink mission. GO Navigator will recover the fairing half from the water.

Per L2, this launch is sliding right a few days.

Scheduled Launch Date and Time (UTC)
December 31, 2019     04:40
January 4, 2020          03:24

The launch time has regressed 19 minutes/day between the two data points.  (76 minutes / 4 days = 19 min/d)
If the change of launch time is a linear relation, then this can be extrapolated to future dates.

January 5     03:05
January 6     02:46
January 7     02:27
January 8     02:08

EDIT 1/1 close but no match

The next SpaceX Falcon 9 rocket from Cape Canaveral is scheduled to launch the next set of Starlink internet constellation satellites from pad 40 on January 6 at 9:19pm EST. The launch window is instantaneous.

SFN's schedule shows the launch as on January 6, ~9:20 pm Eastern (January 7, ~02:20 UTC).

It may be new year's day but the fleet is hard at work! Here's a look at OCISLY's progress since Monday.

The droneship has deviated away towards calmer seas now that the launch date has slipped to NET Jan 7th at 02:19 UTC. There's no requirement to be at the LZ so early.

Departure! GO Quest and GO Navigator are underway for the Starlink L2 mission.

GO Quest will support the droneship landing whilst GO Navigator will recover a fairing half from the water. Ms Chief will not take part in this mission because of minor damage sustained last time out

The launch time gets 21-22 minutes earlier each day.

which would appear to account for the difference between your "January 7 02:27" and the  "January 6 at 9:19pm EST" so I guess the 04:40 was either approximate for Dec 31 or station keeping adjs between Dec 31 and Jan 4th.

Fair winds and following seas GO Ms. Tree. They have begun the Starlink mission before the morning weather catches up to them. #SpaceXFleet #Starlink

Starlink L2 Fleet Update!

GO Navigator is heading towards the Port of Morehead City, having peeled away from OCISLY.

The droneship and accompanying ship GO Quest are not too far behind and could possibly follow the same.

1/5 Using a pre-launch state vector provided by SpaceX, we used STK's HPOP to propagate the orbit and fit Supplemental TLEs (SupTLEs) for the first 8 hours following deployment. Data can be found at https://celestrak.com/NORAD/elements/supplemental/.

2/5 Data assumes nominal launch on Jan 7 at 02:19:21 UTC and deployment at 03:20:32.598 UTC. TLEs are produced for the full stack and for a single object to provide a range of drag characteristics.

...

5/5 Visualization of the orbit--which can be viewed in real-time mode--is available via the globe icon next to the TLE data. A link to a short YouTube video showing how to use Orbit Viz can be found at https://youtube.com/watch?v=SmI5gx7ifS0.
