Latest analysis shows 288 debris objects confirmed from #Cosmos1408 breakup. This Gabbard diagram shows the apogee / perigee for 253 of these objects with orbits fit by LeoLabs (real data, not simulated).

Of note, some objects have perigees <420km that cross into #ISS orbit. pic.twitter.com/q4LPMRwBui
