While me and my friends are watching the moon at the beach late at night. I saw something lighting up in the night sky that came out of nowhere, they look like 3 fireballs just floating in the sky from the north heading south then disappears after 30 seconds. I took a video and was wondering if it’s just lanterns but it’s so random and weird. I don’t think lanterns are as bright as that and they are floating at the same parallel speed.
