Third stage ignition?

T+12 minutes. Very confusing coverage.

All satellites separated (expected).

They seem to have performed the last satellite separation (or expected to, not sure by the commentary or views):

Sorry about the watermark. I forgot to take it off my bandicam recorder after doing Starbase member clip from Mary 😅

Livestream showing lots of replays. Apparently, the launch is on track.

Success for South Korea's Nuri (KSLV-2) rocket, which has deployed NEXTSat-2 and several CubeSats following launch from the Naro Space Center's Launch Complex 2 (LC-2).

Some other spacecraft seen separating (assuming not live?), in particular looks like the SNIPES? Or perhaps also interspersed with the Lumir-T1, KSAT3U and JLC-101-v1-2 CubeSats, unsure. Also, not all of these appear to be onboard, with the graphics showing just 5 satellites overall.

Although I'm getting the sinking feeling they may actually be showing KSLV II's F2 separations from last year (?), just to show what this flight's would look like in the absence of live views? The first separation attached below looks like PVSAT, and four 4U Cubesats were released afterwards, but the SNIPES are 4x3U! See last images regarding PVSAT and NEXTSat-2.

Scratch that, the payload stack is visible in the last attached image, and NEXTSat-2's horn is visible on the top of the separated spacecraft in today's coverage, confirming it was indeed showing today's separations, as expected. Looks like there were only 5 CubeSats apart from NEXTSat-2 though, judging from the visible canisters around the main payload, which also appears to fit the timeline graphs.

Fairing separation and the first cubesat separating, which I missed previously.

Thanks, Steven for covering a very confusing launch coverage.  You did well despite the numerous conflicting replays and lack of English translation.
