BlueWalker 3 Redux
Anthony Mallama, Richard E. Cole, Scott Harrington +4
The BlueWalker 3 satellite is now fainter than during the first months after deployment. The greatest improvement is that the average maximum luminosity near zenith has been reduce…
Brightness Characterization for Starlink Direct-to-Cell Satellites
Anthony Mallama, Richard E. Cole, Scott Harrington +1
The mean apparent magnitude of Starlink Mini Direct-To-Cell (DTC) satellites is 4.62 while the mean of magnitudes adjusted to a uniform distance of 1000 km is 5.50. DTCs average 4.…
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…
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…
