The last working day before the holiday season was well spent at the Cabauw research site, including a beautiful sunrise. We don’t get those much in The Netherlands these days. Happy holidays!

Low-frequency inaudible sound (#infrasound) observed from Asteroid #2024BX1 (Sar2736) across Europe - up to 1615 km distance at CTBTO infrasound array IS43. Nearest observations (e.g., CTBTO array IS26 at 412 km) clearly shows a moving source.
