Ajisai reflectivity study published
A new study on Japanese Geodetic Satellite Ajisai, led by Dr D Kucharski, has just been published online. Using a photometry observation system in Graz, Austria, the reflectivity of Ajisai surface could be very precisely monitored.
Otsubo is one of the coauthors.
Title: Hypertemporal photometric measurement of spaceborne mirrors specular reflectivity for Laser Time Transfer link model
