Does anyone know if it’s launching on the 26th or not it’s very conflicting

SpaceX has updated their Launches webpage for this launch.

Quote from: SpaceX
SpaceX is targeting Wednesday, May 26 for the next Falcon 9 launch of 60 Starlink satellites from Space Launch Complex 40 (SLC-40) at Cape Canaveral Space Force Station in Florida. The instantaneous window is at 2:59 p.m. EDT, or 18:59 UTC, and a backup opportunity is available on Thursday, May 27 at 2:38 p.m. EDT, or 18:38 UTC.

Falcon 9’s first stage booster previously supported the Sentinel-6A mission. Following stage separation, SpaceX will land Falcon 9’s first stage on the “Just Read the Instructions” droneship, which will be located in the Atlantic Ocean. One half of Falcon 9’s fairing previously supported four Starlink missions, and the other previously supported a Starlink mission and the Transporter-1 mission.

I'm estimating the launch time to be 18:59:35 UTC (2:59:35 PM EDT).

It's the payload separation time of 20:03:23 UTC (4:03:23 PM EDT) subtracted by the mission duration (1 hour, 3 minutes, 48 seconds).

Sometime this morning yesterday's L-1 weather forecast was posted to the PSFB website.  (As of 01:20 EDT this morning the website still had Monday's L-2 weather forecast.)

There was no change to the forecast anyway.  Still 90% 'Go' for today and 80% 'Go' for tomorrow with all additional risks Low.

In an otherwise nondescript launch attempt, SpaceX goes for 100 successful flights in a row. Quite a milestone.

https://arstechnica.com/science/2021/05/is-spacex-reliable-company-goes-for-100th-successful-flight-in-a-row-today/

Edit to clarify: Eric explains that he’s not counting Amos-6 as it wasn’t a flight. So the 100 flights goes back to December 2015.

Good afternoon from the Cape, where I promise a Falcon 9 rocket is standing at the other end of this heat haze. Liftoff of 60 Starlink satellites (29th) set for 1459 ET. Weather looks good.

This says that coverage starts at 3:00 EDT / 19:00 UTC.
That's a minute after the launch time in the tread title.
Is launch slightly later than previously anticipated?

What kind of wastrels would dump a perfectly good booster in the ocean after just one use?

SpaceX launch coverage starts 15 mins before launch.

Unfortunately SpaceX schedules the webcast videos for launch time (but on a 5-minute mark) rather than when coverage is actually going to start.

The 18:59 UTC launch time is correct.  As Jansen noted, SpaceX will start coverage around 15 minutes before that.

Fun tidbit from the NSF stream: this flight marks a reuse milestone for the fairings, as one of the halves will be making its 5th flight. The other half is making its 3rd flight. Both fairing halves have flown more flights than the booster itself!

T-20 mins vent. Falcon 9 B1063-2 (a youngster by SpaceX standards) set to launch the Starlink L28 mission from SLC-40.
