(54402) Jonathanbradshaw Main-belt Asteroid
Discovered on 4 June 2000 by J. Broughton at Reedy Creek.
Jonathan Bradshaw (b. 1965) is an English-Australian occultation observer who in 2021 noticed the single blink of a star 7.4 radii from dwarf planet Quaoar where no event was expected. Independent observations by R. Langersek and J. Broughton led to it being reported to Paris Observatory as a Neptune-like ring, with nothing detected on the outbound side.Naming citation (WGSBN Bull. 5, #17, 20), IAU / Minor Planet Center, via NASA/JPL
