The first reported observations of Darksat have been published by
Tregloan-Reed et al in Astronomy and Astrophysics:
https://arxiv.org/pdf/2003.07251.pdf
- SeeSat magnitude estimates would still be very much of interest!
Also, my own Starlink paper, which acknowledges the work of SeeSat
observers, is in press in Astrophysical Journal Letters
and you can see the preprint  at
