Significant #fireball over Germany this evening: youtube.com/watch?v=qQFVOHSBGDw. Many visual reports, too: fireball.amsmeteors.org/member

Only four days after the Ohio event another daylight #fireball yesterday, this time over Texas and again with at least one meteorite fall: ares.jsc.nasa.gov/meteorite-fa (with early strewnfield map) and fireball.amsmeteors.org/member. Videos of the fireball: facebook.com/groups/meteoritec and facebook.com/groups/meteoritec and facebook.com/groups/meteoritec. And the meteorites: fox26houston.com/news/houston- and facebook.com/Fox4DFW/posts/pfb

Multi-Sensor Trajectory Reconstruction of the 24 April 2025 Alaska #Fireball and Implications for Planetary Defense: arxiv.org/abs/2603.22630 -> "On 24 April 2025 at 18:30:57 UTC, a bright daytime fireball over Southcentral Alaska was detected by 37 seismic stations, 16 single infrasound sensors, and four infrasound arrays, yielding 30 ballistic and multiple fragmentation arrivals. The unprecedented density of seismoacoustic coverage enabled detailed reconstruction of the event using acoustic signals, with fragmentation source locations further guiding the identification of Doppler weather radar signatures of a meteorite fall. Incorporation of a radar-derived terminal point yielded a final trajectory solution, which agreed closely with an independent optical trajectory solution from video analysis. [...] This uniquely well-recorded event demonstrates the capability of dense seismoacoustic networks to constrain bolide trajectories, energetics, and fragmentation, with radar and optical data providing critical confirmation and complementary perspectives."

A rare daylight #fireball coming with a loud bang was seen and heard Tuesday morning over the U.S. and Ohio in particular: youtube.com/watch?v=dHBjApk3d6w - see skyweek.wordpress.com/2026/03/ for links to many more reports. And ares.jsc.nasa.gov/meteorite-fa says: "Signatures of falling meteorites are seen in data from three weather radars [...] NASA Meteoroid Environment Office finds that this was a 2m diameter object weighing around 6 metric tons - more of a small asteroid than a large meteoroid. [...] There are meteorites on the ground around Windfall, OH towards River Styx, OH."

It seems likely that a bright #fireball on the morning of the 12th dropped #meteorites in #Bavaria, says the Czech analysis meteor.asu.cas.cz/cz/post/boli based on data from special cameras: the body came in slowly and at a very shallow angle, so the potential strewnfield is huge and thus a systematic search not viable, and one can only hope for discoveries by chance.
