A day with some clouds and rain, but also sun. Towards dusk
the sky cleared more and more. Still thin clouds and some thicker
clouds, but with nice clearings in between.

Could image 43145 18005A FIA Radar 5 on 2 passes, both low in
north. In the 2nd pass the predicted mag was 8.4 and the satellite
was seen using Sattools compressing the track to 1 point.
