I just saw ISS pass overhead while still reasonably light - looked away then looked again and there did appear to be something very close behind it
There’s an undocking due of a secondary unmanned vehicle - was planned for yesterday but timings got a bit flexible due to the nuaka problems and haven’t had time yet to catch up with what has gone on with that.
(edit to add just checked and I gather that undocking of the Pir module has been delayed again, until Monday, so you didn’t see that)
FWIW the likes of the Heavens-above prediction site above had Nuaka crossing European skies last night about 25 minutes or so
ahead of the ISS.
That ties in with other apps which yesterday PM had Nauka as the leader of the pair so to speak, by about 10000 km..
(been overcast here last two night..grrrr)
