 Great article Jonathan and thanks for the attribution.  When the weather finally clears here, I will turn my attention to darks at and the others.
 This is exactly the sort of thing we need instead of all the bologna that’s going on in the press. Vis-à-vis my rant of a few days ago. For those lucky few of you on the blind cc list who missed my rant:

The first reported observations of Darksat have been published by
Tregloan-Reed et al in Astronomy and Astrophysics:

- 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
