What this is
People are riding this Falcon Heavy. SpaceX is launching them from Kennedy Space Center, FL, USA. Everyone who loves them will be watching the clock.
SpaceX is flying a Falcon Heavy from Launch Complex 39A, Kennedy Space Center, FL, USA. Mission: Gateway PPE & HALO. The Power and Propulsion Element (PPE) and Habitation and Logistics Outpost (HALO) are the foundational elements of NASA's lunar-orbiting space station "Gateway". The PPE is a 60-kilowatt class solar electric propulsion spacecraft that also will provide power, high-speed communications, attitude control and the capability to move the Gateway to different lunar orbits. The HALO is the pressurized living quarters where astronauts who visit the Gateway, often on their way to the Moon, will work. It will provide command and control and serve as the docking hub for the outpost. HALO will support science investigations, distribute power, provide communications for visiting vehicles and lunar surface expeditions, and supplement the life support systems aboard Orion, NASA’s spacecraft that will deliver Artemis astronauts to the Gateway. Planned orbit: Lunar Orbit. Status: To Be Determined. Current date is a placeholder or rough estimation based on unreliable or interpreted sources.

Too far to see
You will not see this rocket from Centennial, Colorado. It is about 1,575 miles east. The broadcast is the view.
That is too far for the flame and, for almost every launch, too far for the high-altitude plume. Dim the lights and watch together anyway.
