A Bidirectional Reflectance Distribution Function for VisorSat Calibrated with 10,628 Magnitudes from the MMT-9 Database

  title={A Bidirectional Reflectance Distribution Function for VisorSat Calibrated with 10,628 Magnitudes from the MMT-9 Database},
  author={Anthony D. Mallama},
A BRDF for the VisorSat model of Starlink satellites is described. The parameter coefficients were determined by least squares fitting to more than 10,000 magnitudes recorded by the MMT-9 robotic observatory. The BRDF is defined in a satellite-centered coordinate system (SCCS) which corresponds to the physical shape of the spacecraft and to the direction of the Sun. The three parameters of the model in the SCCS are the elevations of the Sun and of MMT-9 along with the azimuth of MMT-9 relative… Expand

Starlink Satellite Brightness Before VisorSat
The mean of 830 visual magnitudes adjusted to a distance of 550 km (the operational altitude) is 4.63 +/-0.02. The data on DarkSat, the low-albedo satellite, indicate that it is fainter than theExpand
A Flat-Panel Brightness Model for the Starlink Satellites and Measurement of their Absolute Visual Magnitude
The Starlink satellites are shaped like flat panels. The flat sides face zenith and nadir during normal operations. Their brightness is determined by the product of the solar illumination on theExpand
The Brightness of VisorSat-Design Starlink Satellites
The mean of 430 visual magnitudes of VisorSats adjusted to a distance of 550-km (the operational altitude) is 5.92 +/-0.04. This is the characteristic brightness of these satellites when observed atExpand
Impact of satellite constellations on astronomical observations with ESO telescopes in the visible and infrared domains
The effect of satellite mega-constellations on astronomical observations in the visible, near-infrared, and thermal infrared domains is estimated using a simple methodology, which is applied to ESOExpand
The Low Earth Orbit Satellite Population and Impacts of the SpaceX Starlink Constellation
I discuss the current low Earth orbit artificial satellite population and show that the proposed `megaconstellation' of circa 12,000 Starlink internet satellites would dominate the lower part ofExpand
Concerns about ground based astronomical observations: a step to safeguard the astronomical sky
Understanding the risk for astronomical community, a set of actions are proposed in this paper to mitigate and contain the most dangerous effects arising from such changes in the population of small satellites. Expand
Analysing the impact of satellite constellations and ESO's role in supporting the astronomy community
In the coming decade, up to 100 000 satellites in large constellations could be launched into low Earth orbit. The satellites will introduce a variety of negative impacts on astronomy observatoriesExpand
Impact of Satellite Constellations on Optical Astronomy and Recommendations Toward Mitigations
The SATCON1 report concludes that the effects on astronomical research and on the human experience of the night sky range from “negligible” to “extreme” and led to recommendations for observatories and constellation operators. Expand
Massive photometry of low-altitude artificial satellites on Mini-Mega-TORTORA
The nine-channel Mini-Mega-TORTORA (MMT-9) optical wide-field monitoring system with high temporal resolution system is in operation since June 2014. The system has 0.1 s temporal resolution andExpand
