Have you seen the Mayak satellite?

On July 14, an amateur group in Russia launched a small satellite called
Mayak. They said it would become the 'brightest shooting star' in the sky.
Why’d they do it? Here’s how to look for it.

A team of young Russians – led by Moscow State Mechanical Engineering
University (MAMI) – managed to raise more than $30,000 on Russian
crowdfunding website Boomstarter, in order to launch their own small
satellite. The satellite is called Mayak, which means beacon in English.

It’s a cubesat, roughly the size of a loaf of bread. And it’s up there.
Mayak went into space on July 14, 2017, as part of a secondary payload,
launched on a Soyuz 2.1v vehicle from Baikonur Cosmodrome in Kazakhstan.

It’ll be orbiting Earth, about 370 miles (600 km) high, for the coming
month. It’s supposed to be very, very bright, so bright that it would,
supposedly, ruin night skies and threaten astronomy.

Satellite tracking websites like Heavens Above are already trying to follow
it, hoping to offer information on Mayak’s passes over various parts of the
world.
Heavens Above commented: "A new small satellite has just been launched
which will deploy a large reflector once in orbit and has the potential to
be very bright. We now have a provisional orbit from Space-Track which you
can use to generate predictions. Please note that the magnitude estimates
are possibly very inaccurate until actual observations are reported."

Heavens-Above.com now has pass predictions up for the new Russian reflector
sat "Mayak," listing it as NORAD ID 2017-042F/42830.

Plus Mayak has its own app, available to those who back the project.

How bright is Mayak? Brightness estimates have varied, but the idea was
that it would be the brightest shooting star in the sky.
Some estimated it would be nearly as bright as Venus, the sky’s brightest
planet. Its brightness is part of its purpose, which is partly, simply, to
inspire people.

>From Mayak’s website: The main objective of the project is to make
cosmonautics and space research poplar in Russia, as well as to make
scientific and technical researches attractive to youth.

Also from Mayak’s website:

Question: Why did you build the satellite?
Answer: Everyone is used to think that flying into space is a privilege of
state and military corporations. We wanted to prove that space is simpler
and closer than it seems, and a team of enthusiasts can launch a satellite
into space!
