The US Space Force’s SLD 45 unit says a 10:20PM Falcon 9 launch and a 11:04PM Falcon Heavy one could be the quickest back-to-back Earth to orbit launches in the Eastern Range (via CNBC). The launches would beat NASA’s Gemini 11 mission in 1966 which launched two rockets one hour and 37 minutes apart.

If you want to watch the launches, check out the livestreams for the Falcon 9 Starlink mission and the Falcon Heavy Hughes Jupiter 3 Mission.
