Do we have any reports of Mayak actually being observed yet? Heavens Above shows it as 42830/OBJECT F, but if this is correct, the deployment has not yet occurred, since there is no differential motion relative to other objects in relative proximity.  - TS

From this article,
https://spaceflightnow.com/2017/07/14/soyuz-rideshare-launch/, it looks
like Mayak was probably dispensed into a 584 km x 604 km orbit at 97.61
degrees inclination. I do not know if it successfully deployed, or if the
reflector is stuck in the cubesat, or if it exploded into a million mylar
pieces which might still be visible.

On Friday Jul 14th 2017 at 6;36 Ut a Soyuz 2-1A will launch with 73
payloads.
The main payload is Kanopus V-IK, several micro satellites and a lot of
Cubesats
with 8 Lemur-2 and 48 Flock 2k satellites in a 98 degree orbit.

But the one to watch for is MAYAK (russian for Lighthouse or Beacon), a 3U
Cubesat
that will deploy a tetrahedral reflector with sides of 4 sq m.
The sat wil rotate in all 3 directions and by reflecting the sunlight it
could reach
mag -10, much brighetr than ISS (mag -4) or the Iridium-1's (mag -8).

See the article on Spaceflight101.com<http://Spaceflight101.com> with 2 video's and photo's.

Should be a nice object to watch and image.
