A loud boom rattled windows and prompted calls to police departments in several towns along the shoreline Friday night.

People from Ledyard to East Haven and Milford reported hearing the loud sound and feeling their houses shake around 10 p.m.

"In Madison the whole house shook, the windows rattled," Susanna Maresca Bakula wrote on Facebook.

An expert at Yale’s Peabody Museum today confirmed it was a meteorite that hit a house in Wolcott, on Williams Court. Minerology Collections Manager Stefan Nicolescu says neighbors might want to check their yards.

“It is very likely that there is a dispersal field,” Nicolscu said.  “These things usually don’t come down in one piece, they shatter, so they get dispersed over sometimes quite a significant area.”

The rock is a chondrite meteorite.

Die Region kann nun wirklich als 'Meteoritenfalle' gelten, denn bereits 1971 und 1982 fielen in nur 30 km Entfernung bereits zwei Meteorite im selben Ort: Wethersfield (jeweils ein L6 Chondrit)

Ein brillianter Dialog zwischen einer Reporterin und einer älteren Dame:

"Did you see or hear any of it?"
"No"
"Why not?"
"I was asleep!"

Manche haben aber auch ein Glück im doppelten Sinn des Wortes :-) Robert and Wanda Donahue saßen ja gerade draussen und schauten sich M*A*S*H im Fernsehen an, als sie den dumpfen Knall im vorderen Teil des Hauses vernahmen und meinten, da sei ein LKW durch die Haustür gebrettert.

wow tolle Kruste hat das Stück für so ein schönes Teil würde ich sogar ein größeres Loch in meiner Decke in kauf nehmen wenn ich nicht gerade darunter stehe.

Wenn ich mich nicht irre, müsste der Meteorit übrigens genau hier eingeschlagen sein:

Ein zweiter Meteorit wurde in einem anderen Gebäude in Waterbury gefunden.

There are no known witnesses to this rock landing, so no certainty exactly when it fell. It was found intact, 1 1/2 pounds, about 2 inches by 2 1/2 inches by 4 inches, and appears to have crashed through the gutter of the home on the property.

Wolcott        41°36.452’N, 73°0.742’W

Connecticut, United States

Fell: 19 April 2013

Classification: Ordinary chondrite (L5)

History: Shortly after 10 PM on 19 April 2013, a loud boom was heard east to west across southern Connecticut, from Ledyard to Milford. The police departments in Ledyard, Madison, Guilford, Branford, East Haven and Milford received calls from the public reporting the booms. At that time, Lawrence L. Beck, Jr., was watching TV in his home in Wolcott, Connecticut, when he heard a loud noise coming from the attic and saw holes forming in his dining room ceiling. The next day (Saturday, 20 April 2013) Mr. Beck went to the attic to check out what happened, and found a rock split in two, a damaged copper pipe and a hole in the roof. He reported the damage to the Wolcott Police Department. The same day Mr. Beck also contacted John J. Bagioni, a family friend with a background in science. Upon seeing the rock, Mr. Bagioni suggested it might be a meteorite. He also suggested the nature of the rock be checked with the Yale Peabody Museum of Natural History in New Haven, Connecticut. On Monday, April 22, 2013 a Wolcott police officer brought the smaller of the two pieces to the YPMNH where it was confirmed to be an ordinary chondrite. Both pieces were later sold by Mr. Beck to Darryl Pitt of The Macovich Collection who later resold the main mass to the MMGM.

Physical characteristics: The total mass of the meteorite was 838 g. The rock split upon impact in two large pieces and a few small ones; the largest piece weighs 597 g, the smaller one is 221 g. The two large pieces fit together and establish that the piece was completely covered by black fusion crust. Fresh surface is light gray.

Petrography: (Stefan Nicolescu, YPMNH). Composed of sparse, recrystallized chondrules, up to 2.5 mm across (size range: 0.6 - 2.5 mm; average size: 1.0 mm) in fully crystallized silicate matrix interspersed with kamacite, taenite and troilite. Both barred and porphyritic chondrules are present. Feldspar is mostly microcrystalline (<5 μm) with very few large (up to 0.2 mm) crystals in the matrix.

Geochemistry: Mineral compositions and geochemistry: Mineral chemistry by EMP. Olivine (Fa24.2-25.1; N=10), orthopyroxene (Fs20.5-21.4Wo0.9-1.6; N=10), clinopyroxene (Fs7.3-8.2Wo44.8-45.5; N=4), plagioclase (An9.3-11.5Or4.3-6.4; n=10)

Classification: Ordinary chondrite (L5)

Specimens: 20 g, including two polishe-thin sections and one polished mount at YPMNH; the main mass is held by MMGM.
