Time: October 25, 2024, 19:06 Location: Surabaya, Indonesia (Approximately 10km from Juanda International Airport) I captured this video on my mobile phone. The object I estimated to be about 3km away. I watched it for approximately 25 minutes in total, the object remained pulsing and slowly descending. I saw this with my own eyes, and it did not appear to behave like the surrounding aircraft.
