There is the following video taken in Vytegra, Russia on 22 of June. (warning: strong language in Russian)

According to
this site, there were no launches on this date. One was on 21st of June from Baikonur, Kazakhstan, and the other from Plesetsk on 27th of June.
Kazakhstan is too far away to think it would be visible, but just in case this particular launch from Plesetsk wasn't mentioned, used google maps to see the distance between both cities.

Seems too far away too, but maybe not? In any case, it wasn't mentioned on the site. So this one is unannounced.
Wonder if it fits the following:

Q: (Perceval) The thing that we thought was a comet over Kazakhstan, was it a rocket from the Russians as reported?
A: No.
Q: (Perceval) Was it a comet?
A: Yes.
Q: (Perceval) It looked like a comet from what we know about comets.
A: Fragment. Expect a lot of the "rocket launch" excuses. If it was really a "rocket launch" they would have been able to announce it in advance.
