This fireball is especially important because the mother or father meteoroid was once noticed telescopically sooner than it hit the ambience. This makes it an extraordinary alternative to hyperlink telescopic knowledge of an asteroid with its breakup habits within the environment to glean perception into its inner construction.

Researchers requested locals between Port Weller and Virgil, Ontario, to be in search of fragments of the gap rock. Brown stated:

We all know from digital camera information and climate radar which tracked falling particles from the fireball that meteorites virtually unquestionably made it to the bottom close to or east of Grimsby. What we want now to finish this tale is to get better a few of these rocks and in finding out what sort of subject material made up asteroid 2022 WJ1. That is very similar to a pattern go back area undertaking, however on this case the pattern fell on us.

First file of the upcoming affect

Ye Quanzhi, a College of Maryland astronomer who research asteroids, comets and meteors, reported on Twitter at 1:13 a.m. EST on November 19:

Seems like an area rock goes to fall into Lake Erie space in ~2 hours (about 3:30 am EST)

He shared the hyperlink for NASA’s Middle for Close to Earth Object Research Danger Overview web page. The article, C8FF042, is now got rid of from the web page as it has struck Earth and is subsequently now not a danger.

To be had now! 2023 EarthSky lunar calendar. A novel and wonderful poster-sized calendar appearing stages of the moon each night time of the 12 months! Makes an excellent gift.

Exact prediction

This might were fascinating to peer, however a minimum of I were given to listen to it. I had for some explanation why woken up and a couple of seconds later the home cracked because it does when hit by way of a gust of wind after which there was once a muffled rumble for 2 or 3 seconds.

Some observers reported the fireball at magnitude -10 to -20.

The ones few hours of lead time had been sufficient that some had been ready to seize C8FF042 with telescopes.

Did you notice it? You’ll file the fireball with the American Meteor Society right here.

Asteroid now named 2022 WJ1

David Rankin came across asteroid C8FF042, which the Minor Planet Middle has since named WJ1. The details about the newly came across asteroid circulated at the Minor Planet Mailing Record (MPML). It stated:

Invoice Grey has the affect level at 19 Nov 2022 8:26:54.47 UTC, lat +43.12309, lon W80.26416, which is without delay over Brantford, Ontario, Canada.

Sam Deen at the MPML stated:

The article could have an excessively grazing affect of simply 10-12 levels or so, and must be travelling WSW To ENE between Detroit and Buffalo. We must almost definitely be expecting a lovely impressive gentle display, bearing in mind the low perspective and top inhabitants of the world.
