Captute of the ACS3 - stands for ADVANCED COMPOSITE SOLAR SAIL SYSTEM trail taken from Setúbal-Portugal while it was crossing the sky in a South/North over Spain.
As Its orbit is over 1000km high, almost twice the orbit of the ISS, and its smaller size makes it difficult to observe and record, which can only be achieved in exceptional visibility conditions as the magnitude is very low , 4.3 in this case.
The nature of its "sails" produces a pattern of reflections in intensity and color different from what is observed in the passages of the ISS and TIANGONG.
This photo is probably the first record of the passage of this new satellite taken from Portugal.
