I don't really know how to read this page, but it looks like the time of closest approach has already passed - > Closest approach time of impactors: t_min = 2023/08/14 04:48 TDB and t_max = 2023/08/15 12:22 TDB If so then we're all good. Can the poster or anyone else chime in with background on this?

I am not an expert, but my interpretation was the same as yours. TBD seems to be roughly UTC time. In which case, this passed by 8 hours ago.

I saw this tweet: https://twitter.com/ByronDrury/status/1691487518590402560?s=20 https://twitter.com/ByronDrury/status/1691487518590402560?s=... linking to https://cneos.jpl.nasa.gov/scout/#/object/ZTm0038 https://cneos.jpl.nasa.gov/scout/#/object/ZTm0038 It has some cool graphs that seem to show a lot of uncertainty in closest approach time [edited to fix second link]

  Well, that NASA page has the closest approach going into next week and a ~10% of impact, so... hopefully the big disclaimer at the top is relevant.

    Are you sure? I chose another asteroid by random in the selector and it looked even worse.
