Presentations at #ACM2023 about #2022WJ1 flashing in the sky over Niagara last year by @teddykareta, Paul Wiegert, & @meteordoc.

Highlighting the disappointment of the meteorites being underwater right off the coast of the lake.

One rock might have landed on the ground, but nothing yet found between snow & grape vines.

An interesting thing I've just noticed:

In the past year, atmospheric monitoring has reported 7 or 8 impacts onto Earth with energy ~1 kiloton TNT-equivalent or more - https://cneos.jpl.nasa.gov/fireballs/ .

Three of those have been found in advance: #2022EB5, #2022WJ1, and now #2023CX1.

For those not familiar with these things:

The brightness and estimated distance to the newly-discovered asteroid #Sar2667 give a very approximate size of ~1 m.

It will flash harmlessly in the sky, as we saw when asteroid #2022WJ1 did the same thing over Niagara last November.

For fun, I tried spinning view around the earth, to better show the trajectory of impact asteroid 2022WJ1 on Nov 19, 2022 at 8:27 UTC. Line are drawn down to the surface for every 1 minute of motion. #Astronomy #2022WJ1

Here's a view simulated view of 1-meter "asteroid" 2022 WJ1's motion on 11/19/22 before impact (from JPL Horizons).
It went into earth's shadow at 7:59 UT, 28 minutes before impact, although even sunlit it would have been below naked eye brightness before hitting the atmosphere. Tick marks are 1 min. #astronomy #2022WJ1

An incredible achievement by the planetary defense community! #2022WJ1 was a tiny asteroid on a collision course with Earth. But astronomers saw it coming, and NASA’s Scout impact hazard assessment system calculated where it would hit: https://www.jpl.nasa.gov/news/nasa-program-predicted-impact-of-small-asteroid-over-ontario-canada #CNEOS #PDCO #NASA #Scout #PlanetaryDefense

A small asteroid burned up over Southern Ontario Saturday morning, and was followed by another bright fireball Saturday night.
- the first is now one of only six asteroids that were discovered prior to impact, and it may be the only one that impacted over a heavily populated area!
