Three more launches have been set for June. Today from the Cape, a SpaceX Falcon 9 rocket will launch the SES 22 communications satellite for SES of Luxembourg. Built by Thales Alenia Space, SES 22 will provide C-band television and data services in the United States. This will include another barge landing, and the launch window is 5:04 - 7:13 pm Eastern. Webcast HERE Late tonight or tomorrow, a Virgin Orbit LauncherOne rocket will launch on its fifth flight after dropping from a modified Boeing 747 carrier jet. The mission will be Virgin Orbit’s third operational launch, carrying seven small satellites for government agencies sponsored by the U.S. military’s Space Test Program. Virgin Orbit calls this mission “Straight Up.” This one will fly from off the West Coast, and they say video will be available but it's a night launch and video would have to come from a chase plane so don't expect much. Window is 10:00 pm - 1:00 am Pacific. (1:00 - 5:00 am Eastern) Later on Thursday and from the Cape again, a United Launch Alliance Atlas 5 rocket will launch the USSF 12 mission with Wide Field Of View, or WFOV, experimental missile warning satellite for the U.S. Space Force. WFOV hosts a new type of infrared staring sensor in geosynchronous orbit to detect the heat from missile launch plumes. The USSF 12 mission will also launch the USSF 12 Ring spacecraft, a rideshare payload hosting several additional classified experiments. The rocket will fly in the 541 vehicle configuration with a five-meter fairing, four solid rocket boosters and a single-engine Centaur upper stage. Launch window is 6:00 - 8:00 pm Eastern. ULA's webcast will be HERE

Who determines launch times and assigned orbits?
Is there a NOTAM on launch and reentry?

That's not an easy question to answer, but VERY simplified: The satellite owner/operator decides on the orbit it wants. The launch provider then calculates the best path and launch time to achieve that orbit. Complicating factors include the rocket's capability, other satellites or objects already in orbit that might conflict, sun angle and position for heating and power generation, sun activity (which changes the upper atmosphere's density and/or increases radiation), availability of tracking stations, weather, shipping schedules near the launch site, and several more I could remember if I had more time.
Yes, there are NOTAMs for aviation, and Coast Guard notices for shipping.

Found a link to the nightime Virgin Orbit launch. It will be active about 15 minutes before the airdrop. LINK

The Virgin Orbit launch got delayed until tonight. The ULA Atlas launch is still on for today and they are preparing to begin fueling it. Liftoff at 6:00 pm Eastern.

Launch is holding at T-4 minutes due to weather. Improvement is expected.
Thunderstorms at the Cape on a June evening. Whoda thunk it, huh? LOL!

Scrub for today's try due to thunderstorms in the area. They'll try for a 24-hour re-cycle. The opening of the launch window for tomorrow is still 6:00 pm Eastern.

One hour until the planned liftoff. The weather guessers give launch a 50/50 chance today due to (what a surprise) thunderstorms in the area. They are currently "no-go" for weather and conditions are expected to worsen.
