Me too. While covering the launch, I was going to ask “Does it look like the vehicle is tumbling out of control?”, but decided not to because I remembered the dogleg maneuver needed to get to SSO.
Four new objects catalogued as "H-2A DEB". Not clear what they could be.
Debris was from GOSAT-2 H2A's upper stage (F40), which broke up about a year and a half ago after undergoing a partial deorbit, and had an almost head-on trajectory wrt ISS.
The debris object that ISS avoided is now available on SpaceTrack as 2018-084CQ, 46477, from the breakup of Japan's H-2A F40 rocket stage. At 2221:07 UTC it passed within a few km [of the position ISS would have been at if it hadn't maneuvered] at a relative velocity of 14.6 km/s, 422 km over the Pitcairn Is in the S Pacific.
