The Brightness of Starlink Mini Satellites During Orbit-Raising

Anthony Mallama, Richard E. Cole, Jay Respler +3

Observations of Starlink V2 Mini satellites during orbit-raising suggest that SpaceX applies brightness mitigation when they reach a height of 357 km. The mean apparent magnitudes…

Starlink Mini Satellite Brightness Distributions Across the Sky

Anthony Mallama, Richard E. Cole, Jay Respler +3

The illumination phase functions for Starlink Mini satellites are determined for times of twilight and darkness. Those functions are then evaluated to give apparent magnitudes over…

Assessment of Brightness Mitigation Practices for Starlink Satellites

Anthony Mallama, Andreas Hornig, Richard E. Cole +4

Photometric characteristics for all models of Starlink satellites launched to date are reviewed. The Original design that lacked brightness mitigation is the most luminous. SpaceX…

Starlink Generation 2 Mini Satellites: Photometric Characterization

Anthony Mallama, Richard E. Cole, Scott Harrington +4

Starlink Generation 2 Mini satellites are fainter than Gen 1 spacecraft despite their larger size. The mean of apparent magnitudes for satellites in brightness mitigation mode is 7…

BlueWalker 3 Satellite Brightness Characterized and Modeled

Anthony Mallama, Richard E. Cole, Scott Tilley +2

The BlueWalker 3 (BW3) satellite was folded into a compact object when launched on 2022 September 11. The spacecraft's apparent visual magnitude initially ranged from about 4 to 8.…

Roll Angle Adjustment Dims Starlink Satellites

Anthony Mallama, Jay Respler

The brightness of Starlink satellites during orbit parking and orbit raising decreased significantly in 2020 when the operator modified their orientation. The mean apparent magnitu…
