3 Juno is a large asteroid with a mean diameter of about 235 km, but the remaining bodies are all small. (32326) 2000 QO62, the brightest of those clearly in the visible clump would have a diameter of about 6 km, given the same albedo as 3 Juno. This indicates that it is probably a so-called cratering family composed of ejecta from impacts on 3 Juno.
The HCM analysis by (Zappalà 1995) determined several likely core members, whose proper elements lie in the approximate ranges
