2024 RW1, previously known under its provisional designation CAQTDL2,[5] was a 1-meter-sized asteroid or meteoroid that struck the Earth's atmosphere and burned up harmlessly on September 5, 2024, at around 12:40 a.m. PHT (September 4, 16:40 UTC) above the western Pacific Ocean near Cagayan, Philippines.[5][6] 2024 RW1 is the ninth impact event that was successfully predicted,[7] which was discovered by Jacqueline Fazekas at NASA-funded Catalina Sky Survey.[8]

Ground observation

[edit]

Despite the presence of Typhoon Yagi over the Philippines that the European Space Agency (ESA) initially said "might obscure the view of the asteroid", several observers reported seeing the fireball, including those who posted videos on social media.[9]
