I could not find them at JPL, MPC, Lowell nor Space Weather. Only Horizons. I fetched the elements from the MPC discovery pages - https://minorplanetcenter.net/db_search/...id=2022+KH. 96 obs over 2 days by the big guys. Used those figures to come up with brightest on ~May 21 22:00:00CDT altitude 31° 111"/min mag 16.28. Closest shows as May 22, 10:52:34CDT altitude -72° 130"/min, mag 16.78ish. Distance 1,475,127Km. Those Aussies may have a chance ;+) Tracking south thru Libra towards Crux but with an uncertainty of 7, suspect the error window might be large but CNEOS says 1 minute.
