According to TFRs the Starlink launch is Wednesday but that kind of doesn’t seem right
NROL-87 likely has taken priority across all ranges for SpaceX.
I guess that but it’s on the same day around 2 hours before NROL 87 unless it takes the backup window

I wonder if someone at the FAA messed up when they were deleting TFRs after today's CSG-2 launch, because what is out there for tomorrow is for CSG-2.  Maybe they meant to delete tomorrow's CSG-2 and deleted tomorrow's Starlink 4-7 instead.

The TFR's are right

Why are there range problems no problem happened with launch of tursat 5b and starlink 4-4

Why do you think there are “range problems”?

And a word of advice: you’re new to NSF. Please post less and read more until you catch up on the usual terminology and are familiar with how SpaceX conducts their operations. You’re causing a lot of needless confusion with your posts in the SpaceX mission threads.

Launch Photography, updated January 31 after the CSG-2 launch, states the Starlink 4-7 launch will be on February 1, at the already noted times, or on February 2, with no times given.

Launch for the 53 and 53.2 degrees inclination Starlink launches is 20 to 22 minutes earlier per day.

My calculated times:
February 1 at 18:56 and 22:13 UTC.
February 2 at 18:34 and 21:51 UTC.

However, the above is inconsistent with the information that this launch will be after the NROL-87 launch from Vandenberg on February 2, 20:18 UTC.

My interpretation is as early as February 3, not within the next hour on the same day.

We now know the Astra Rocket launch from Canaveral is scheduled for February 5 or 7.

Edit: My interpretation was wrong.  Launches:
NROL-87 Feb 2, 20:18 UTC
Starlink Feb 2, 21:51 UTC, 93 minutes later

I could simply see SpaceX wanting to give their teams a break to avoid 6 consecutive days on console and running procedures at the pad. Starlink 4-7 has no schedule pressure, so this one launch can slip for human reasons.

The sooner this one flys the sooner ASOG will be ready for next flight. If JRTI is out of action for a while longer, ASOG availability may be the dominant restriction on upcoming launches?

But yes it is possible that starlink production or something else means this doesn't matter.

Looks like a one day delay:

Very likely a 2 day slip however, highly doubt they can do NROL and this within like 2 hours.

Also a chance NROL slipped a day but guess we will see.

NROL-87 didn't slip and they can do those two launches in under 2 hours.

This is just a taste of what SpaceX wants to do in 2022, the first will be a new record between the shortest time between two missions.

L-1 weather forecast.  80% 'Go' for February 2.  70% 'Go' for February 3.  Booster Recovery Weather risk is Moderate for February 3.  All other Additional Risk Criteria are Low.

Why would they delay Starlink 4-7 if it and NROL-87 are on two different coasts? Is it too much work for the launch teams?

SpaceX has the capability to support both launches, the only thing that makes me curious will be the NROL-87 deployment as we might see the 4-7 launch first than the NROL-87 deployment, but we will know once SpaceX posts the information on their website.

Not a world record, several Soyuz launches have happened even within minutes from each other.

OK found 22 July 1969 with 25 minutes apart so this is alright

No new NGA Rocket Launching notice for the delay to February 2, even though I received these two new cancel-and-replace Space Debris a couple of hours ago.  (I held them, waiting for the Rocket Launching notice to show up.)

Also (not based on these notices), I've calculated for the February 3 backup day:
February 3 at 18:13 and 21:30.
