There are reports that the brightness of some of the Chinese #Qianfan satellites is varying on short timescales. (e.g., https://www.satobs.org/seesat/Mar-2025/0049.html)

This behavior suggests that these satellites (and possibly others) from the second Qianfan launch are currently tumbling in orbit.

"It looks like there's no stopping the march of modern internet satellites, and many more look to be blighting our skies/potentially improving worldwide internet access in the near future."

Brightness of the #Qianfan Satellites: https://arxiv.org/abs/2409.20432 -> "Observed magnitudes of Qianfan spacecraft range from 4 when they are near zenith to 8 when low in the sky. Nearly all of the observations can be modeled with a nadir-facing flat antenna panel and the underside of a zenith-facing solar array, both with Lambertian reflectance properties. These satellites will impact astronomical research unless their brightness is reduced."

Kiina lähetti juuri taivaalle ensimmäiset satelliitit, joista rakentuu ajan kanssa Elon Muskin Starlinkin kanssa kisaava Qianfan -satelliittinetti.
