IAU CPS Statement on BlueWalker 3
The International Astronomical Union Center for the Protection of the Dark and Quiet Sky from Satellite Constellation Interference expresses concern about the recently launched prototype BlueWalker 3 satellite’s impact on astronomy. New measurements reveal that this low Earth orbiting satellite is now one of the brightest objects in the night sky, outshining all but the brightest stars. In addition, the satellite’s use of terrestrial radio frequencies poses a new challenge to radio astronomy.
