Audio dropped out, but the Go-No Go poll is completed, they are Go for launch.

SECO

Now coasting.  Elliptical parking orbit.

Look at the picture junction between Earth, space, and engine bell.

Good elliptical transfer orbit.  Next burn at apogee to circularize orbit before satellite separation.

Funky? RocketLab music. 🎶

On this mission, the fairings dropped off at about 105 km, which is fairly typical.  Presumably RocketLab would drop them earlier if they could, to increase performance and margins.  But they did not, which makes me think the fairing deploy is set by payload constraints.  But this in turn makes me wonder about how Neutron will fare, since it wlll need to expose the payload to space at a much lower altitude.

Second second stage burn completed.

Successful satellite separation.

Sign-off.

Congratulations to the launch campaign team!
Thanks, jdon759.

Here is a comparison of the two Rocket Lab missions for Synspective, 'The Owl's Night Begins' (Electron F17), and 'The Owl's Night Continues' (Electron F24).

Both missions were to SSO, and below I've mapped the F24 launch hazard areas from the NGA notices upthread.

There are several differences in the webcast telemetry, including:

1. F24 throttled back less for MaxQ.
2. F24 didn't throttle back at all for S1 terminal guidance.
3. F24 had a shorter S1 burn, with more loft, but less velocity and altitude at MECO.
4. The F24 S2 burnt at a lower acceleration generally, but for longer, using the enhanced batteries mentioned in the webcast commentary to provide more overall S2 impulse.

Today's launch also featured the red recovery/reuse rings on the Electron, but on the webcast it was mentioned that there would be no recovery attempt, they were just testing some of the components and still expect to attempt a heli-catch in the coming months.

We might see a few more of these satellites launch on Electron as they had planned to use Soyzu. Targeting an initial constellation of 6 satellites in next year or two, with 30 being long term goal over coming years.
