For the record, these satellites are inserted in groups of 60 at half their orbital height. They have onboard thrusters to boost up to the final operational orbit. There is high atmospheric drag at lower altitudes, so they deploy their solar panels horizontally during this boost period, which usually lasts less than a month. These horizontal panels reflect the sun just after sunset and just before dawn. Once they are at their final height they rotate the panels so they are much less reflective. Basically, the constellation's effect on the night sky is proportional to the number of launches in the last month, not the total number in orbit.
