Starlink Internet Sats in 350 km Orbits

Hello Everyone,

SpaceX is proposing to orbit 19,440 Starlink internet satellites at the
very low altitude of 350 km. These would be quite bright but most would be
eclipsed by the time that twilight turns to darkness.

The US Federal Communications Commission is considering the company’s
request. One of their concerns is the impact on astronomical observing. In
the article linked below I predict the magnitudes and distribution of these
spacecraft across the sky.

Meanwhile, Richard Cole informed me that the satellites in Starlink launch
10-1 have stopped orbit raising at about 350 km. Their designations
indicate that they are not Direct-to-Cell spacecraft. So these could be the
first very low altitude internet sats, possibly in a testing state.

I welcome observed magnitudes for these objects. The reporting format that
I prefer is given in the article linked below, but I will try to work with
observations in other formats.

Best regards,

Tony Mallama
