2 bright yellow orange lights traversing south to north slowly climbing then disappeared

About 11:40 pm 7/4/23 saw first object flying south to north, bright yellow orange flickering light climbing slowly in sky. Another object followed behind along same trajectory and same appearance. Continued climbing and started turning east while climbing. First one then the second disappeared into clouds presumably. Seemed to have bright central light and 2 or 3 smaller lights flickering or blinking close to central light. Was not fireworks. Looked at Flightradar24 app at 11:44 pm, no planes appeared anywhere close to that trajectory or in a pair. I would guess altitude at 5,000 feet but difficult to tell. My impression was they were low. They were seen in the direction of the airport from my vantage but were not following typical flight paths. The lights were larger and brighter than airplanes. No sound of engines could be heard.
