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,[9] including those who posted videos on social media.[10]
