Seems like there should be time to do it mid/late Oct and allow time for JPSS [launching on] 1 Nov?So has it been delayed? And if so, do we know why?

NGA Rocket Launching + Space Debris notice in costume for Halloween as a generic Hazardous Operations notice.
Spaceflight Now is showing the launch being one day earlier, October 27 between 00:01 - 01:00 UTC (October 26, 5:01 - 6:00 pm PDT).

I wonder if he got confused when doing the date adjustment and adjusted the date for UTC (instead of EDT+PDT) to the 27th, then adjusted EDT+PDT to the 26th.

Targeting Thursday, October 27 for a Falcon 9 launch of 53 Starlink satellites to low-Earth orbit from SLC-4E in California →
SpaceX is targeting Thursday, October 27 for a Falcon 9 launch of 53 Starlink satellites to low-Earth orbit from Space Launch Complex 4E (SLC-4E) at Vandenberg Space Force Base in California. The instantaneous launch window is at 6:14 p.m. PT (01:14 UTC on Friday, October 28), and a backup opportunity is available on Friday, October 28 at 5:52 p.m. PT (00:52 UTC on Saturday, October 29).The first stage booster supporting this mission previously launched Sentinel-6 Michael Freilich, DART, and five Starlink missions. Following stage separation, the first stage will land on the Of Course I Still Love You droneship, which will be stationed in the Pacific Ocean.A live webcast of this mission will begin about five minutes prior to liftoff.
Will be there

A #SpaceX #Falcon9 launched a minute after sunset yesterday evening from #Vandenberg SFB (B1063.8, #Starlink Group 4-31).At 6500' though, the sun was still up...
The sun is flattened by atmospheric refraction, and looks a bit rattled by shock (sound) waves from the rocket exhaust.I didn't quite get everything lined up like I wanted, but being off center shows more of the wave propagation.
and also, from the consistency of the webcast data, I'm seeing no evidence for any dogleg maneuvers alluded to up-thread in this mission. An optical illusion may be the more likely culprit.

Vandenberg's minimum azimuth for range safety is 158 degrees When exactly could the dogleg have been performed? Immediately after fairing separation?No, the dogleg should be part of the first stage burn. A dogleg is least expensive when done at as low a velocity as possible.Here's a picture that shows the likely location. The more vertical line is a plot of 158o from Vandenburg. The other line is plotting backwards from the droneship position. At the latitude of the droneship, a 56.2o inclination orbit passes overhead at an azimuth of 140o = asin(cos(56.2)/cos(29.62)). Reversing this course yields 320o. Both plots were made with this GPS Visualizer. I then superimposed the two plots.So if done as an impulsive maneuver, it would be done a little south of the channel islands. In practice it's more efficient to do this as a gentle curve.
Lou, if SpaceX had done what you suggest, the launch hazard area for the ASDS would make no sense, because it wouldn't align with the booster ground track. But what they did is odd as well, because they actually flew at closer to 142° from North, much less than 158°. Perhaps 158° is out of date?For an orbital inclination of 53.2° from a latitude of 34.633°, the launch azimuth in the inertial frame is 180 - 46.72 = 133.28°. However, in the orbital frame of reference, it is 180 - 44.73 = 135.27°. So, they were about 7° short of the required azimuth.Perhaps this difference was made up by a second S2 burn at apogee, or even by the satellites themselves? Or a bit of both?
