And...launch success confirmed. It was indeed a Long March 4C launching at 07:27 UTC w/ a certain "Yaogan 34", described as an optical remote-sensing satellite built by SAST. http://t.cn/A6cnB5ha

This launch puts the obscure (due to its payload usually classified or plain civil domestic EO sats) Long March 4 series at 6 out of 6 in 2021 so far, just 1 short of Soyuz and firmly in 3rd place for usage frequency. Official reports has it flying "around 14 times" this year.pic.twitter.com/bBuuXGrlzo

This is also the first LM-4 series launch from Jiuquan using the larger 4 m diameter payload fairing. Previously such launches were all from Taiyuan.pic.twitter.com/KJ80aqzJ1t

Regarding the destination of the satellite, there were speculations of it making a dogleg to SSO, however there's an observation of what looks like rocket stage venting in New South Wales Australia ~30 min later which fits w/ this one & in ~60 deg. LEO. http://satobs.org/seesat/Apr-2021/0169.html …

Tracking data from
@18SPCS: 2021-037A/48340: 1083 x 1105 km x 63.38° (S/C) 2021-037B/48341: 983 x 1091 km x 63.45° (rocket) Interesting orbit for an optical EO sat, and even more interestingly YG-34's co-orbital w/ the YG-31-01 triplet "Chinese NOSS" satellites! I wonder...

If it is an imaging sat and it passes slightly after the triplet it could be used for precise identification. But it could also be SIGINT.

Yeah I was thinking about the same thing, cross-identification of targets at the same time. BTW YG-34 is co-orbital with YG-31-02 triplets launched this January, not Group 01 launched in 2018.

I checked and it is behind the triplet, however it could maneuver so we will have to wait a little bit to confirm.

If it's indeed an imaging sat working with those triplets, there should thus be two other Yaogan-34 to launch soon?

That was indeed mentioned as a possibility on Chinese forums. If this theory is correct I expect at least 1 of these in each “Chinese NOSS” orbit plane.

Very likely indeed, at least for the recently-launched triplets. There could be a direct sat-to-sat link between the triplet and YG-34, to avoid relying on geostationary relays.
