Meteorite strike in the Channel
Asteroid Sar2667 aka meteorite 2023 CX1 impact was projected to hit 3 km off Cap Fagnet on the Normandy coast where sea bed is 18m deep, actually hit 4 km offshore at 2:59 London time today.
Was only the 7th such object in history to be detected prior to impact.
Energy before atmo entry: 100 tons TNT estimated.
Size before entry: About 1 meter diameter.
Noise from impact predicted to be 59db on the beach, 9 secs after strike.
'Splash crater' 24m wide.
Average interval between impacts of this size somewhere on Earth is 1/10 year.
First projection was for a North American impact later in the day, but more data refined the splashdown point & time.
Ten years and four days ago, the much larger Cheylabinsk meteor was estimated at around 400-500 kilotons, over three orders of magnitude larger.
