Large pulsing circle of energy framed by black square. Mistaken for planet until it changed shape and flashed. 3 smaller black crafts.

Just before 9 pm a large bright light appeared in the sky above the beach. We first thought it was a planet until it started flashing and changing shape. I began taking photos and video with an iPhone 13. On the monitor, I could see an intense spinning circle of energy framed by a pitch black square. It hovered over the beach for over 20 minutes. Reviewing the video clips, two smaller dark triangular can be seen about the large object in the 11 o’clock position. Another object appears below it in the 5 o’clock position. The object then drifted back towards the North Virginia Beach neighborhood until it could no longer be seen. On the video clip, you can see it flashing, changing colors, seemingly growing larger and smaller. It’s quite active.
