Somewhat odd notice. It starts on the 29th, identifies as for a rocket launch, but the times don't align with a 1-day delay of 10-34. However, the zones in the notice are exactly identical to the previous notice for 10-34, and these are actually the only notices to use these exact zones, as SpaceX is always changing the precise limits of its hazard zones. The only other feasible option could be an attempt at a quick turnaround of 39A after Ax-4, but if that was the case, we should have seen other signals of this hypothetical launch, and Ben Cooper's choice to put "Upcoming launches include more Starlink batches." after MTG-S1 on July 1st implies there aren't any more undiscovered Starlink launches scheduled in June. My guess for now is that this notice is for 10-34, but this is something worth keeping an eye on.

Pad 40 launch plan looks ambitious:

June 23rd  05:58 UTC ASOG Launched
June 25th  19:54 UTC JRTI Launched, 2day 13 hour 56 minutes pad turnaround
June 28th 04:26 UTC ASOG planned, 2 day 8 hour 32 minutes pad turnaround, 4 day 22 hour 28 min ASDS
July 1st 21:03 UTC JRTI planned, 3 days 18 hour 37 min pad turnaround, 6 day 1 hour 9 min ASDS

ASOG has just left Port Canaveral.

Possible record turnaround for pad  [Edit: and East coast droneship on this launch Not for drone ship and only just for pad and launch might be delayed yet so certainly not guaranteed to happen]?

Possible record turnaround for pad and East coast droneship on this launch?

It appears that this list might have two "pad turnaround" records. The first, beat the previous record by nearly two hours, and the second will improve the current record by another 5 hours and 25 minutes.

It won't be a record turnaround for an East coast droneship, ASOG's record turnaround is 3 days, 12 hours, and 13 minutes between Starlink Group 6-60 and 6-64.

It appears that this list might have two "pad turnaround" records. The first, beat the previous record by nearly two hours, and the second will improve the current record by another 5 hours and 25 minutes.

The current SLC-40 turnaround record is 2 days, 8 hours, 59 minutes, and 30 seconds between Starlink Group 12-21 and 12-16 in March. The recent turnaround from 10-23 to 10-16 was about 5 hours slower than this record, and the pad turnaround scheduled from 10-16 to 10-34 is currently planned to pass the record by about 28 minutes and 20 seconds.

My bolds:

SpaceX is targeting Saturday, June 28 for a Falcon 9 launch of 27 Starlink satellites to low-Earth orbit from Space Launch Complex 40 (SLC-40) at Cape Canaveral Space Force Station in Florida. Liftoff is targeted for 12:26 a.m. ET [04:26 UTC], with backup opportunities available until 4:26 a.m. ET [08:26 UTC]. If needed, additional opportunities are also available on Sunday, June 29 starting at 12:04 a.m. ET.

A live webcast of this mission will begin about five minutes prior to liftoff, which you can watch here and on X @SpaceX. You can also watch the webcast on the new X TV app.

This is the 5th flight for the first stage booster supporting this mission, which previously launched CRS-32, NROL-69, GPS III-7, and a Starlink mission [1092-5]. Following stage separation, the first stage will land on the A Shortfall of Gravitas droneship, which will be stationed in the Atlantic Ocean.
