This looks like a NOSS trio - fun to watch. Those are listed at Heavens-Above,

show up in the list of satellites for the night, because are quite faint.


From main heavens-above page klick "Select staellite" and enter "NOSS%" in the
Satellite name box.

Just to pick a nit, you should enter NOSS 2-% The three groups of
triplets are all second-generation NOSS. I don't think any of the
first generation satellites are flying in formation (although it's
been a while since I looked for any of them.)

Thanks for the information. I've seen NOSS 2-2 and also 2-1 (I think)
and was assuming that the rest are also flying in formation (although
I heard these were by pairs, not triplets). Now I know better, :-)
