A <1m object has struck🌍in the skies above Niagara Falls, becoming a safe #fireball. For just the 6th time, global #asteroid warning systems saw it pre impact, alerting #PlanetaryDefence experts where & when. 'Only' 6x, but this capability is rapidly improving #AsteroidImpact☄️
Another #imminent_impactor has been spotted 🤩 Likely less than 1 metre in diameter, this will become a pretty and harmless fireball to observe. #C8FF042 Predicted time of atmospheric entry is 8:26 UTC, over the great lakes.

Yesterday, newly-discovered asteroid 2022 UR4 passed just 10674 km above India and Sri Lanka, much closer than our geostationary satellites. It is 3-10 meters across. https://t.co/3fpUzcnqot

@QHYCCD @RoyalAstroSoc In addition, the height of the two maxima is quite different, indicating that Cacus is not only quite elongated but also irregular in shape. It is also a rather fast rotator, with a rotation period of only 3.76 hours.

Lightcurve of Apollo-type asteroid 161989 Cacus The asteroid shows strong variations in brightness, by almost 1.5 mag, somewhat larger than the values reported by other observers, who have seen light curve amplitudes between 0.8 and 1.1 mag #QHY42Pro #IAWN @QHYCCD @RoyalAstroSoc
